Scope

 

ANSI / API 5L specifies the manufacture of two product levels (PSL1 and PSL2) of seamless and welded steel pipe for the use of a pipeline in the transportation of petroleum and natural gas. For material use in a sour service application, refer to Annex H; for offshore service application, refer to Annex J of API 5L 45th Edition.

 

API 5L pipes may be classified according to the following criteria:

execution: seamless or welded (seamless pipes may be used up to 24 inches, LSAW above 24 inches, ERW up to 20 inches)
specification level (API PSL1, PSL2): PSL1 is a standard quality used for pipelines, whereas PSL2 sets more stringent chemical, mechanical properties, and testing requirements
surface finish: black, varnish painted, anti-rust oil, galvanized, coated externally (3PL) and/or lined internally
ends types: plain, beveled, threaded ends
The main advantages of API 5L pipe are:

Resistance to cracking forces that may propagate in long pipelines
Sour service suitability
Rather inexpensive and long service life (at least grades B, X42)
Size Range

API 5L pipes are available in dimensions between from 2 to 28″ (seamless execution) and up to 80″ in welded execution (generally, LSAW i.e. longitudinal submerged arc welding).

The API 5L and ASME B36.10 pipe dimensions and weights are, in fact, identical.

Process

 

Ingots, blooms, billets, coils or plates used for the manufacture of pipe shall be made via basic oxygen, electric furnace or open hearth in combination with a ladle refining process. For PSL2, the steel shall be killed and melted according to a fine grain practice. Coil or plate used for PSL2 pipe shall not contain any repair welds.

Application:Tube for conveying gas, water, and oil in both and natural gas industries etc.

Casing:Casing is a large diameter pipe that serves as the structural retainer for the walls of oil and gas

wells, or well bore.It is inserted into a well bore and cemented in place to protect both subsurface

formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take

place. Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi.

Tubing: Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to

the surface after drilling is complete. It is made to withstand the pressure generated from the extraction

process. Tubing is manufactured in the same way as casing, except that an additional process known as

"upsetting" is applied to thicken the pipes.

Pipe elbows

 Elbows, also known as “ells,” are used to change the direction of a pipe system. An elbow typically features a 45, 90 or 180 degree bend, although other angles are also available. Elbows come in a variety of diameters and are generally threaded for connectivity. A common example of an elbow fitting in the home is the piece that extends from the wall of your shower to which the shower head connects.

pipe-elbows
Wall thickness: SCH5 to SCH160When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.
Elbows are categorized based on various design features as below:
Long Radius (LR) Elbows – radius is 1.5 times the pipe diameter
Short Radius (SR) Elbows – radius is 1.0 times the pipe diameter
90 Degree Elbow – where change in direction required is 90°
45 Degree Elbow – where change in direction required is 45°

Size range: 1/2 to 56 inches (DN 15 to DN 1,400mm)

Cold Drawn Seamless tube, Cold Drawn Seamless tubing

 Cold Drawn Seamless tubing (also known as CDS). Cold Drawn Seamless tubes offer tight tolerances compared to Hot Finished Seamless tube, and offers stronger physical properties compared to other mechanical tubing.cold-drawn-seamless-tube

CDS is popular in the hydraulics, being used to make hollowed chrome plated telescopic cylinders and hydraulic rods. It is also popular for large bore, heavy walled, high pressure hydraulic cylinders. Cold Drawn Seamless tubes also find uses in heavy equipment manufacturing such as cranes and garbage trucks.

BARREL TYPE CROSS ROLL PIERCING PROCESS

tube_plug_drawing_process
This cold drawing process continues until the tube is at its specified final dimensions.

In this process, rounds are heated in the rotary hearth furnace/ slope type fixed bed heating furnace to a forming temperature of approximately 1280 degree C. This is followed by a high pressure water jet descaling, prior to which the bloom is pierced in the cross roll piercing mill to produce a thin-walled hollow shell which is elongated to between 3 and 4.5 times its original length. The elongation corresponds to a deformation level between 65 % and 75%. Owing to the relatively large angle of roll inclination, and higher rolling speeds, stock exit speed in the case of barrel-type piercer is considerably faster than in Mannesmann piercing mills.

A considerable proportion of the seamless tubes and pipes manufactured through the cold roll piercing technology undergo subsequent cold forming. The principal reasons behind cold drawing are:

Achievement of closer wall thickness and diameter tolerance
Improvement in surface finish
To enhance serviceability
No premature failure
Suitable for critical forming Such as 180˚ Bends
Enhancement of mechanical properties of the tube
Expansion of product mix towards the lower end of the OD and wall thickness scales.
THERE ARE THREE BASIC PROCESSES EMPLOYED FOR THE COLD DRAWING OF TUBE:
Hollow drawing
Stationery drawing or floating plug drawing and
Drawing over a mandrel (also known as drawing on-the-bar)
ANNEALING
After the goods are cold drawn to sizes, the tubes are put on annealing furnace for heat treatment and normalising.

STRAIGHTENING
Post annealing, the goods are passed through a seven roller straightening machine to achieve proper straightening of the tubes.

EDDY CURRENT
Post straightening, each tube is passed through eddy current machine to detect for surface cracks and other defects . Only the tubes that pass eddy current are fit for delivery to customers.

FINISHING
Each tube is either oiled with corrosion resistant oil or varnished for surface protection and corrosion resistant as per customers requirement, each tube end is covered by plastic end caps to avoid damage in transit, the marking and specs are put and the goods are ready for dispatch.

Pipe tee

 Pipe Tee is a type of pipe fitting which is T-shaped having two outlets, at 90° to the connection to the main line. It is a short piece of pipe with a lateral outlet. Pipe Tee is used to connect pipelines with a pipe at a right angle with the line. Pipe Tees are widely used as pipe fittings. They are made of various materials and available in various sizes and finishes. Pipe tees are extensively used in pipeline networks to transport two-phase fluid mixtures.

Straight tee and Reducing tee

 The primary purpose of a Tee is to make a 90° branch from the main run of pipe. Standard there are 2 possibilities, on behalf of the equal tee and reducing tee. The equal tee (or straight tee) is used as the branch has the same diameter as the run-pipe.

Straight-tee-and-Reducing-tee

The reducing tee is used as the branch has a smaller diameter as the run-pipe.

Dimensions and Standards of pipe tees
When we talk about a tee NPS 3, a equal or straight tee is intended. With a tee NPS 3 x 2 a reducing tee is intended. Although, officially a reducing tee will be indicated by 3 diameters, namely 3 x 3 x 2 (A x B x C). The A & B measure stands for the Nominal Pipe Size of Run-Pipe, C measure stands for Nominal Pipe Size of Outlet.
This designation actually is superfluous, but comes from the time that tees were available in 3 different ends of diameters, such as 4 x 3 x 2 (A x B x C). In this implementation of course it is necessary, to specify 3 different sizes.
That kind of tees is probably no longer available. Applying a equal tee with a concentric or eccentric reducer is now the usual practice.
A straight or equal buttwelding Tee is available for all common diameters.
A Reducing Tee not, because many diameters are not produced, or can not be produced.

As an example: a reducing tee NPS 6 x 4 is a standard item for most suppliers, but a reducing tee NPS 16 x 2 is probably not available by any supplier.
It would also not economical to use a NPS 16 tee with a NPS 2 outlet; in such situations a Branch Fitting will be used or a Branch Connection will be made.
In addition to the defined tees, there are straight and reducing crosses.
Straight crosses are generally stock items, reducing crosses are often difficult to obtain.
I have never used that tees and I have they never seen in practice, at least not in petro and chemical industry. They will be used where space is limited, by revision work, in shipping industry et cetera.

Wall thickness Tee
By the shape of a tee, the wall thickness can be a critical item. ASME B16.9 only standardizes the end-to-end dimensions, center-to-end dimensions and some “squareness” dimensional tolerances. The wall thickness at the weld line location even is standardized, but not through the rest of the fitting. The standard states that the minimum tolerance will be within 12.5% of the minimum ordered wall thickness of the pipe. A maximum tolerance is specified only at the ends of the fitting.

tee-design
Pipe tee & crosses size

Many providers of welding tees (and elbows) provide one schedule greater thickness so that sufficient wall thickness, after forming, remains. In Tee’s, the crotch radius (T) varies from one manufacturer to another, but some establish itself as a requirement, 1.3 times the wall thickness to maintain the crotch.

ASME B16.9-2003 SECTION 2.2 DESIGN OF FITTINGS SAYS:
…it is expected that some portion of formed fittings may have to be thicker than the pipe wall with which the fitting is intended to be used
Because there is no maximum tolerance for some parts of the fitting, the customer itself must indicate his requirements. Depending on a customer specification, the manufacturer must certify that the manufactured tee, is made the requested requirements.
He can do that with additional drawings, with additional wall thickness measurements etc. verified by an independent party or a customers inspector.
All these additional tests cost money, so it can happen, that the additional costs, many times higher, as the tee itself.

Pipe reducers

 Pipe reducers be applied, to change from pipe diameter in one direction. Standard there are 2 possibilities, the concentric reducer, is usually used in vertical pipe lines, and the eccentric reducer that is used in horizontal pipe lines.

pipe-reducers
Reducer is a kind of fitting that be used for reducing piping size. Concentric reducer is most commonly used and often eccentric reducer used in piping in about pump and pipe rack area.

Length of reducers
The length of a Reducer is very short in relation to the diameter, so in some dimensions the transition from one to another diameter is very abruptly. For example, a reducer 6″ x 2½” has a length of 140 mm. On this short distance a pipeline will be reduced from 168.3 mm O.D. to 73 mm O.D. During the design phase of a new pipe system, a piping designer certainly must think about it.

 

Length of reducers
For wall thickness less than 3 mm, the reducers are supplied with plain weld ends. Larger thicknesses are supplied with the weld bevel of 37 ½°±2 ½°.Weld Preparation

Stub Ends

 Stub Ends are fittings used in place of welded flanges where rotating back up flanges are desired. They are also called Lap Joints and Vanstone Flared Laps. A rotating back upflange seats itself against the back surface of the Stub End. When bolts are added, the clamping action of the bolts presses the rotating back up flange against the back of the Stub End.stub-ends

When bolts are added, the clamping action of the bolts presses the rotating back up flange against the back of the Stub End. The gasket surface of the Stub End then presses against a gasket and another gasket surface providing joints like standard flange joints. The seal is made by the gasket surface of the stub end alone, the flange only provides the clamping pressure on the joint.

Coupling Fittings, Pipe couplings

 Coupling fittings are used for fluid conduits in which each end portion of two tubes to be connected is provided with a swaged-on adapter carrying the necessary means to connect or disconnect the tubes without disturbing the swaged-on adapter. Our range of coupling fittings are available in aluminium, steel and bronze.

coupling-fittings
Pipe couplings are highly demanded in the pipe fitting market. Pipe couplings are fittings that help to extend or terminate pipe runs. These fittings are also used to change pipe size. Couplings extend a run by joining two lengths of pipe. They are known as reduced coupling if they are used to connect pipes of different sizes. Couplings are also known as repair couplings. These couplings are without stops or ridges and they can be fixed anywhere along the pipe length for preventing leak of any kind.

NORSOK standards

 The NORSOK standards are developed by the Norwegian petroleum industry to ensure adequate safety, value adding and cost effectiveness for petroleum industry developments and operations. Furthermore, NORSOK standards are as far as possible intended to replace oil company specifications and serve as references in the authorities regulations.

The standard dictates specific parameters for certifying the necessary facilities and equipment, confirming it functions according to the requirements to manufacture the specified grades. The manufacturer must also have significant experience in producing the qualifying material.  Testing in accordance to requirements set forth in the standard must be made available for review along with the established Manufacturing Summary which details each step of the manufacturing process from begin to end. Qualifications must be certified through a 3rd party witness (EN10204:3.2).

They reference internationally recognized standards while adding requirements found to be effective in battling the stringent environment and stress of the North Sea. .

NORSOK M-630	NORSOK M-630 is an assembly of Material Data Sheets for use in piping systems and includes the material requirements by material grade and form.
NORSOK M-650	NORSOK M-650 was established to ensure manufacturers are knowledgeable and competent to produce specialty alloys such as Duplex, Super Duplex, Nickel Alloys and Titanium.
