产品说明

PETROL STEEL CO., LTD is a professional supplier of ultra-high pressure and ultra-high purity pipe fittings, flanges, and valves. Our company has introduced advanced technology and equipment from the USA and Germany and has a group of professional and excellent technical teams.

Our company focuses on the R&D and production of ultra-high pressure and ultra-high pure pipe fittings and valves and has successively overcome the technical problems of ultra-high pure raw materials for ultra-High Pressure Pipe Fittings, flanges, and valves, the technical problems of the ultra-precision polishing products and alloy steel gasket sealing of UCV Ultra Clean Valves. We reak the monopoly of foreign technology, and become the world's leader in the industry of ultra-high pressure and ultra-high purity pipe fittings and valves.

The ultra-high purity stainless steel and EP polishing process independently developed and manufactured by our company have been successfully used in Surface Mount Ultra Clean Valves such as Uα pressure reducing valves, Xα pressure reducing valves, Pα pressure reducing valves, diaphragm valves, EP pipes, UCR joints, and successfully manufactured to meet semiconductor Pipe fittings, flanges, and valves required for ultra-high purity gas transmission.
