material S620QL quality control

The boiler and pressure vessel steel plates are our main products. Our main conducted standards for boiler and pressure vessel steel plates are (ASME) ASTM (S)A202, (S)A203, (S)A204, (S)A285, (S)A299, (S)A302, (S)A387, (S)A515, (S)A516, (S)A517, material S620QL, (S)A533, (S)A537, (S)A612, (S)A662, (S)A841, EN10028-2, EN10028-3, EN10028-5, EN10028-6, JIS G3115, JIS G3103, GB713, GB3531, DIN 17155, JIS G3116, GB6653, EN10120, etc. Our typical boiler and pressure vessel steel grades are A204 grade B, A516 grade 70, A537 class 1, A537 class 2, 16Mo3, Q245R,Q345R, etc.

Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance. Our shipbuilding steel plate and material S620QL steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas.

During the construction of hot-dip material S620QL galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the material S620QL construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.

It is a modern high-tech professional enterprise integrating scientific research, material S620QL production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as material S620QL process technology development, technology transfer and related technical consulting and technical services.
