The technical conditions are applicable to the high-strength A514Gr. Q alloy steel plate with thickness of 80-152mm. DH40 hull structure steel, A514Gr. Q high yield Strength Quenched and tempered alloy steel plate suitable for the rack of construction machinery and jack up offshore drilling platform. Available steel plate specifications range: thickness 8-650mm, width 1500-4020mm, length 4000mm-17000mm. Our company can supply alloy steel plates every month 500tons.

During the construction of hot-dip DH40 hull structure 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 DH40 hull structure 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.
