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.

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.

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.

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.
