Ship plate SA573 Grade 70 steel for marine engineering

Q345qC steel plate is the steel plate of bridge structure, the implementation standard is GB / T 714-2015 standard. SA573 Grade 70 steel for marine engineering, Q345qC-Z25 steel: Q represents the yield strength, 345 represents the small yield strength, the unit is MPa, q is short for the bridge, C quality grade, corresponding to the corresponding impact temperature and impact work value, Z is the Z-direction performance that is the performance of the steel plate thickness direction, Z25 is the Z-direction Performance level requirements.

X42 steel plate/pipes, API 5L X42 steel plate/pipes, under API 5L standard, we can regard SA573 Grade 70 steel for marine engineering pipe, X42 steel plate/pipes as large diameter pipes. X42 steel plate/pipes is one mainly of Steel for large diameter pipes, API-X42 steel used for pressure liquid transport, oil, gas, water and other liquid transportation, oilfield engineering, ductwork, construction, steel pipe and oil and gas project which use pipes.

During the construction of hot-dip SA573 Grade 70 steel for marine engineering 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 SA573 Grade 70 steel for marine engineering 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.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
