End caps

End caps are usually used for protecting the end of pipe and other fittings, so the shape are designed according to the shape of pipe line.

Features

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

lifting and handling of a pressure vessel

Pipe caps are widely well-known for the utmost output and outstanding results that it gives.

CAPS: Deep Drawing method

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

cap hotforming

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.

SURFACE TREATMENT:

  • Transparent oil, rust-proof black oil or hot galvanized.
  • Special design available All the production process are made according to ISO9001:2000 strictly.
  • Based on different materials, pipe caps include carbon steel cap, stainless steel cap, and alloy steel cap etc.
  • Depending on their construction, pipe caps contain threaded cap, tapered cap and anti-roll cap etc.
