The pipe fittings produced by the company mainly include the following categories:

1. Various kinds of pipe fittings and flanges used in the petrochemical industry. 180° elbow (LR, SR) with thick wall and manifold are the competitive products of our company. In particular, we can produce non-standard fittings, and change the bend angles which could reduce customers' welding work.

2. High temperature, high pressure, thick wall, large diameter fittings used in boiler, power generation; high temperature and high pressure alloy steel, stainless steel pipe fittings used in chemical industry. We have been supplying pipe fittings to Ha Er Bin Boiler, Shanghai Boiler, Wuxi Bolier and Datang Xinyang, now we are their long-term cooperative strategic partner.

3. The pipe fittings and flanges made of special materials are widely used in the industry with high requirements for corrosion resistance, such as Hastelloy, nickel-based alloys, zirconium, titanium, copper nickel, duplex stainless steel; after several years' practice, the company has owned a set of mature manufacturing techniques for manufacturing these pipe fittings, and obtained the patent of Manufacturing Method of Ni-Cr-Mo Alloy Steel Pipe Fittings, which have gained us a good reputation.

4. Pipe spooling, which is usually applied by the large EPC project companies.
Since 2004, we have been producing flanges and other extension products according to the relevant standards GB, HGJ, SHJ, SY, DL, ISO, ANSI/ASME, MSS, JIS, EN, AS, also we have been able to manufacture based on drawings provided by our customers. The annual production capacity is 15000 tons. Products are widely used in petroleum, chemical, shipbuilding, metallurgy, electricity, food, pharmacy and mechanical industries.
