GOST 17379-01 Elliptical Cap Manufacturer – High-Quality Pipe End Caps
we are a professional manufacturer and supplier of GOST 17379-01 elliptical caps, also known as elliptical pipe end caps, used to close off the ends of pressure vessels, pipelines, or process systems. These caps are manufactured according to the Russian GOST 17379-01 standard.
What is GOST 17379?
This standard applies to seamless and welded elliptical caps made of carbon and low – alloy steel..
An elliptical pipe cap (also called an elliptical head or 2:1 elliptical head) is a curved end closure for pressure vessels or pipelines. Its 2:1 crown-to-depth ratio provides uniform stress distribution, making it stronger and more material-efficient than hemispherical or flat heads.
steels – 09G2S and Art. 20, production is regulated in accordance with GOST 17379 – 01.
Due to its shape, the elliptical caps withstands a higher pressure of the medium than the flat welded plug. Our caps can be manufactured in accordance with GOST 17379 – 01, widely used for industrial tanks, boilers, cylindrical pressure vessels.
