Introduction to Head Equipment
Sichuan Jinglei Science and Technology Co., Ltd. is a subsidiary of Sichuan Jinglei Science and Technology Co., Ltd. The company holds production licenses for large high-pressure vessels (A1), design permits for stationary pressure vessels, and the American ASME U stamp certification for pressure vessel construction.
The company’s facility covers an area of 50,000 square meters, with 5,000 square meters dedicated to the head manufacturing workshop. It boasts advanced production equipment and strong technical capabilities, including the largest DN10000×60 cold spinning head machine in China (one 1000-ton pressing machine and one 60×10000 flanging machine), one DN4200×26 cold spinning head machine (one 600-ton pressing machine and one 26×4200 flanging machine), and a 1250-ton hydraulic head press. The facility is also equipped with a φ13000mm×4500mm dedicated head heat treatment furnace, a 6000mm×6000mm×22000mm heat treatment furnace, and a 4500mm×4000mm×14000mm heat treatment furnace. Additionally, there are two radiographic testing rooms for cobalt-60 and accelerators, measuring 9000mm×21000mm and 13000mm×22000mm, respectively.
The company focuses on the manufacture of large pressure vessels. The head manufacturing workshop primarily produces heads for various specifications of atmospheric and pressure vessels ranging from Φ500mm to Φ10000mm (including elliptical, hemispherical, dished, and flanged conical heads), which are widely used in the petroleum and chemical industries. With a commitment to continuous innovation, advanced technology, high-quality products, timely delivery, reasonable prices, and excellent after-sales service, the company has earned high praise from users in pressure vessel manufacturing and installation companies.
