There are more than 200 employees, of whom 90% are professional technical staff, testing personnel and special operation workers.

Our company has nearly 20 years history in manufacturing welded pressure steel pipe, with one set of advanced JCOE production line for SAWL steel pipe, one set of special JCOE production line for ultra-thick wall SAWL steel pipe (which fills the blank in manufacturing small diameter and ultra-thick wall welded steel pipe in China), one set of production line for six-meter-long rolling forming submerged arc welded steel pipe, three sets of unconventional production lines for jointer welded steel pipe and one set of production line for traditional SAWH steel pipe. Our annual overall production capacity is 220, 000 ton.

We are dedicated to the development and manufacture of alloy welded pipe at high temperature, alloy welded pipe at low temperature and high strength structure welded pipe. We can formulate effective and eligible welding process, and prepare special temperature control instrument and large heat treatment furnace during the welding process. The products developed by ourselves are eligible in type-examination which proved by Chinese authority test organization. The Cr-Mo alloy steel pipes and alloy steel pipes at low temperature ( ASTM A691 1 1/4Cr, 2 1/4Cr, 5Cr and GB/T9711 15CrMoR\1Cr5Mo\12Cr2Mo\10MnWVNb\16MnDR\09MnNiDR etc. ) are widely used in chemical industry and nuclear power appliance.

We have advanced equipments, complete control ability for process and heat treatment, and the quality testing means for products. We have API monogram. The products are used in petroleum, chemical industry, natural gas, power, city gas, bridge and many other projects, also used in industrial equipments such as large transportation machinery, windlass device of crane, hydraulic cylinder sleeve, and so on.

We obedience to the mission of dedicated to being the best in the development and manufacture of welded pressure steel pipe in China, to enable Chinese welded pipe to rank in the world, and the operation philosophy of integrity, profession and win-win. On purpose of being a comprehensive company which composed of steel pipe manufacture, logistics and import and export trade, we insist to service customers with scientific method, to the best quality, and to technical progress, continuous innovation.
