Q235NH tower steel stock holder offer you price

Q345E steel plate is a low-alloy high-strength steel plate with good low-temperature impact performance. The steel grade is composed of three parts: Q (Qufu in Chinese spelling) representing yield strength, yield strength value, and quality grade symbol. Q235NH tower steel, Among them: Q represents the yield strength; 345 represents the yield strength value, unit MPa; E represents the grade (passed -40 degrees impact test).

Compared with Q235NH tower steel, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.

During the construction of hot-dip Q235NH tower steel 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 Q235NH tower steel 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.
