For onshore oil and gas pipelines, we recommend the use of titanium, nickel aluminum bronze, duplex stainless steel, and other materials to make the required valves. These materials guarantee longer service life and a replacement cycle.
Pipelines and valves used in offshore oil and gas are subject to salt mist corrosion due to marine atmospheric environment, seawater, seabed sediments and transported fluids. Special alloys valves can bear better corrosion resistance and longer service life.
Weidouli has a wide range off-ball, gate, globe, and check valves which are supplied to the Petrochemical market with materials variety of Hastelloy, alloy 20, monel, etc. Also, bellow sealed gate and globe valves or pressure seal bonnet construction structures.
In view of the needs in the fine chemical industry, Weidouli specially designed titanium and nickel alloy valves to ensure the stability of the valves, to withstand corrosion under different working conditions, to extend the service life, and to increase the productivity benefits of users.
In view of the harsh working conditions of high temperature, high pressure in the metallurgy industry and strong corrosion, easy crystallization and the impurities particles in the conveying medium, our company independently develops special valves for smelting.
To solve the problem of seawater corrosion, we usually choose titanium, (Super) duplex steel, nickel aluminum bronze or austenitic stainless steel to manufacture valves, which ensure service life and longer replacement cycle.
Water treatment requires valves of good corrosion resistance and reliably sealing. Ball valves or butterfly valves are usually used in water treatment to control the flow, opening and closing of water, thus achieving zero leakage and long service life.
Titanium alloy valves act as a very suitable solution for the harsh working conditions of paper industry. Over the years, we have produced various titanium Segment ball valves, titanium knife gate valves and other products for different customers in the paper industry.
Ball valves, gate valves, check valves, globe valves and butterfly valves, made of titanium, nickel aluminum bronze and duplex stainless steel, are recommended for pipeline transportation of liquefied natural gas. Our valves are with bear corrosion-resistance, long service life, and a long replacement cycle.
Valves are mainly used on the pipelines of various systems in power plants to cut or connect the pipeline media. Such as power plant desulfurization system, ash removal system, suitable for the transportation of water, steam, ash slurry, dry powder, and other media.
We can customize valves of different materials and structures. The valve material must be resistant to chloride ion corrosion. Titanium is recommended as a priority since it is hardly corroded by chloride ions.
