#torispherical head

Real photos of our giant horizontal pressure vessel semi-finished products in the workshop! From steel plate rolling and head welding to pipe prefabrication, every welding process is strictly controlled to ensure pressure safety.

A large-diameter elliptical head is undergoing quality inspection preparation, with the matching pressure vessel section in the background. This assembly is the "heart component" of large storage tanks and reactors.

Whether it's stainless steel or carbon steel, the workmanship is neat, the surface is flat, and welding and installation are particularly convenient.

Precise cutting, smooth bevels, and uniform curvature—every detail strictly adheres to industrial production standards.

Whether your end caps are made of carbon steel, stainless steel, or special alloys, and regardless of wall thickness or the number of holes, we can respond quickly and deliver accurately.

The 10,000T hydraulic press enables mass production of ultra-large spherical tank flaps, providing a comprehensive solution of "one-time molding + precise shape control" for spherical tanks of DN9m–18m and plates of 20–100mm thickness.

It combines high strength with excellent low-temperature toughness: tensile strength 485–620MPa, yield strength ≥260MPa, Charpy impact energy ≥34J at -30℃, effectively avoiding the risk of low-temperature brittle fracture.

With the support of professional heat treatment process, stress is effectively eliminated and structural stability is enhanced, making the end caps have better pressure bearing performance and stronger durability, and adaptable to various high-pressure working conditions.
