The company has a complete range of welding materials for pressure equipment in the pressure vessel industry. The products cover various levels of 50Kg-100Kg, including welding rods, gas shielded solid welding wires and submerged arc welding wires.

A series of electrodes for pressure equipment: low-alloy steel and high-strength steel CJ807RH, E12018-G, CJ907RH, CJ107 can meet the matching requirements of 80Kg-100Kg high-strength steel, and the impact at -40°C can reach more than 100J. Cr-Mo series heat-resistant steel CJR207~CJR507 electrodes are used for the welding of pearlitic heat-resistant steel, of which CJR507 still has excellent mechanical properties after heat treatment at 750℃/4h, which can meet the high temperature hydrogen corrosion resistance pipeline welding below 400℃. The low-temperature steel electrodes TWE507N3 and TWE507N7 meet the corresponding low-temperature steel welding requirements, and the Charpy impact energy exceeds 130J at -60℃ and -100℃.

The series of solid welding wires cover 50-62Kg heat-resistant steel supporting products WH55-B2, WH55-B2V, WH55-B2Mn, WH-62B3, etc., which can meet the welding of series Cr-Mo heat-resistant steel.

The submerged arc welding material MCJ62CF/TM.SJ105G has ultra-low S and P control (S≤0.005, P≤0.01), and the impact at -40℃ is greater than 120J. It is used for the welding of 600-700MPa crack arrest steel.

Ultra-low temperature austenitic high manganese steel series welding materials, including electrode TME25Mn, flux cored wire TMF25Mn, submerged arc MCJGMn/TM.SJGMn and TIG welding wire TMW25Mn, manganese content 22.5%-25.5%, yield not less than 400MPa, -196 ℃ with Excellent impact performance, similar metallurgical properties to 9Ni steel, good crack resistance and low cost (30-40% cost savings), is a new generation material in the field of LNG storage tank carriers and other fields.

According to the pipeline steel type, the company is used for API 5L: X60, X65, X70, X80, X90, X100 pipeline steel series low S, P high toughness welding materials for petroleum pipelines. Including low-alloy multi-wire high-speed submerged arc welding MCJ60GX, MCJ65GX, MCJ70GX, MCJ80GX, MCJ90GX, MCJ100GX, etc. This series of welding materials adopts Ti-B series design. The micro-alloy is micro-sized to obtain excellent mechanical properties, and the low-temperature impact can reach more than 170J. At the same time, the developed series of cellulose electrodes E6010, E6011 and E7010 are widely used in pipeline backing welding, which can be welded on one side and formed on both sides, especially suitable for downward welding of annular welds. The developed self-shielded flux-cored welding wires E71T-11 and E71T-GS can be used for all-position welding and have excellent crack resistance and porosity resistance.
