Pressure Vessel Equipment Butt Joint Butt HDPE End Caps


The HDPE pipe cap belongs to one of the boiler parts in the pressure vessel. It is usually used at both ends of the pressure vessel.In addition, it is also used as a welding pipe fitting product at the end of the pipeline for sealing. There are many forms.The HDPE pipe cap is a part of the container, which is connected to the pipe by welding.

The HDPE pipe cap is an indispensable and important part of pressure vessel equipment in petrochemical, atomic energy, food and pharmaceutical industries.This kind of pipe is the end cover on the pressure vessel, and is a main pressure bearing part of the pressure vessel. The function is to seal.

One case is the upper and lower bottom surfaces of the can shaped pressure vessels.In the second case, when the pipe is at the end and is no longer ready to extend forward, the pipe shall be sealed with a head by welding.


Standard: GB / ANSI /JIS / DIN

Drift diameter:DN15-DN1200

Wall thickness:SCH5-SCH160


High toughness: the elongation at break of HDPE pipe cap is required to be more than 350%, generally more than 500%.Corrosion resistance: HDPE raw material has stable performance, is inert material, can resist the erosion of various chemical media.The molecular structure of HDPE cap is very stable and will not produce electrochemical corrosion.

Light aging resistance: contains 2-2.5% evenly distributed carbon black, which can effectively resist the UV damage in the sun.Green environmental protection: HDPE pipe cap processing does not add any heavy metal stabilizer, the material is completely non-toxic, no scaling layer, no bacteria.

This is a kind of safe, sanitary and green pipeline material. PE material can be recycled and will not pollute the environment.

Good wear resistance: in many pipeline materials, the wear index of PE pipe cap is quite small.Long service life: PE tube has high molecular weight and good stability and anti-aging properties.Under normal working temperature and pressure, the service life of PE pipe can be guaranteed to be more than 50 years.


HDPE pipe cap is mainly used for municipal engineering water supply system, indoor water supply system of buildings, outdoor buried water supply system and residential quarters.

It can also be used for underground water supply system, old pipeline repair, water treatment engineering pipeline system, garden, irrigation and other industrial water pipes.

However, it should be noted that PE pipe cap cannot be used for hot water pipeline.For outdoor use, where there is sunshine, shelter measures shall be taken.
