What is pipeline steel plate (steel coil)

As we know line pipe or casing and tubing have two different manufacturing types, seamless and welded. So pipeline steel plate is used to make welded line pipe, including ERW, LSAW, SSAW welding processes. Further more, casing and tubing in API 5CT standard could also be made in welded ERW type, so pipeline steel plate and coils also covers these pipes. (But in most cases, casing and tubing are required in seamless types.)

Deep Drawing method of end caps

One of the most common manufacturing methods for caps, where plate is cut out in a circle and formed by deep drawing.

Deep drawing is the manufacturing process of forming sheet metal stock, called blanks, into geometrical or irregular shapes that are more than half their diameters in depth. Deep drawing involves stretching the metal blank around a plug and then moving it into a moulding cutter called a die.

A drawing press can be used for forming sheet metal into different shapes and the finished shape depends on the final position that the blanks are pushed down in. The metal used in deep drawing must be malleable as well as resistant to stress and tension damage.

How to get high quality pipe cap?

Pipe cap acts as protective device and are designed to protect pipe ends of various shapes. The main purpose of using pipe caps is to waterproof the connections. They are also used to close the the ends of hydraulic or pneumatic pipes and tubes. They are used in the plumbing apparatus of domestic, commercial and industrial water supply lines, machinery and processing equipment etc. They are also fitted on water pump lines with the sole purpose of removing air blocks. Pipe caps are highly demanded as an important category of pipe fittings. If a solvent-weld cap is used to provide for a future connection point, several inches of pipe must be left before the cap; when the cap is cut off for the future connection, enough pipe must remain to allow a new fitting to be glued onto it.

How to connect pipeline with pipe cap?

Pipe Cap is directly welded to die at the end of the pipeline; at the end of the pipeline can also welding flange, then with a blind flange to death, when necessary can open the blind flange, pipeline check inside. The conventional cap holder with pressure pressing made by thick wall; forging; by spinning large diameter. The need for maintenance or even after the connecting line, with blind, not later, with a pipe cap. With the blind plate has the possibility of leakage, there is a long time, and screw rust died, as useless, the heat pipe is not very easy to heat insulation.

End caps FAQs

Pipe Cap are used for connecting pipes of different diameters and find wide applications in various chemicals, construction industries, paper, cement & ship builders.

Bevelled Ends

The ends of all buttweld fittings are bevelled, exceeding wall thickness 4 mm for austenitic stainless steel, or 5 mm for ferritic stainless steel. The shape of the bevel depending upon the actual wall thickness. This bevelled ends are needed to be able to make a "Butt weld".

Welding Bevel acc.to ASME / ANSI B16.9 and ASME / ANSI B16.28

ASME B16.25 covers the preparation of buttwelding ends of piping components to be joined into a piping system by welding. It includes requirements for welding bevels, for external and internal shaping of heavy-wall components, and for preparation of internal ends (including dimensions and dimensional tolerances).

Our in-hourse R&D team developed bevel ends equipment are good using in thickness 2mm to 20mm pipe fittings, guarantee high efficiency and high quality.

Send us your technical drawings

These weld edge preparation requirements are also incorporated into the ASME standards (e.g., B16.9, B16.5, B16.34).

ASME B16.25 (BUTT WELD ENDS)

ASME B16.25 sets standards for the preparation of the ends of components that need to be welded together.

Cut square or slight chamfer, at manufacturer’s option for :

  • t ≤ 0.19” carbon steel or ferritic alloy steels
  • t ≤ 0.12” austenitic alloy steels

Buttweld Fittings general

A pipe fitting is defined as a part used in a piping system, for changing direction, branching or for change of pipe diameter, and which is mechanically joined to the system.

There are many different types of fittings and they are the same in all sizes and schedules as the pipe.

Barred Tee

Image
A barred tee is a tee or any fitting with a branch used in pipelines that is pigged and has a restriction bar welded internally preventing the pig from traveling down a branch connection. Barred tee is a pipe fitting that is used in a pig launcher or receiver system in a piping system to ensure the pig could pass the branch safely. Design considerations for barred tee The barred tee will be used when there is a requirement for pigging. Thus, many of its applications can be found in the pipeline or in the subsea field. The bar plates that welded internally at the branch are to avoid the pig from changing direction or getting stuck at the branch outlet. The design of the bar plates must be in sufficient quantity, thickness and adequately spaced to ensure the smoothness for the pig to run through the main pipe, and at the same time not affecting the flow that was meant to flow through the branch. Normal practice is to ensure that the opening in the branch pipeline after gui...

How to Calculate a Pipe Bend?

Image
Pipe fittings are necessary to join together pipes, or to change the direction of an existing pipe. Pipes and pipe fittings are made of a variety of materials, depending on the fluid or gas being transported. Most pipe fittings tend to be either threaded or able to slip over the pipes they connect. Whether you are using steel pipes of PVC pipes, a chemical solvent is required to create a seal between the pipe and the fittings. Measure the required length of the pipe to be installed, keeping in mind the extra length required where the pipe will be inserted into the fitting. Mark this length on the pipe. How to Calculate a Pipe Bend Whether you are bending pipe for running electrical conduit or a metal project, calculating the bend for the start and end point can be an important factor. While there are different types of pipe benders on the market, they all share a common identification for the operation. Identified on all pipe benders is the size of pipe the unit will bend alon...

ANSI Flange Standards

Image
The American National Standard Institute, ANSI, has been overseeing guidelines and standards for products manufactured through several sectors. WHAT IS ANSI? ANSI-approved flanges are used for the industrial market which handles gas, air and steam process systems. Originally formed in 1918, the American National Standards Institute is headquartered in Washington, DC, and is widely recognized as the American organization responsible for overseeing the national standards and conformity assessment system for products, services, processes, systems, and personnel. ANSI works domestically with American government agencies and organizations, as well as with international entities, to make ANSI standards useful around the world. Prior to the creation of ANSI, standards for engineering and equipment such as flanges were developed by the American Institute of Electrical Engineers (AIEE or IEEE), the American Society of Mechanical Engineers (ASME), the American Institute of Mi...
