bp440 steel armor plate for vessels and boilers in the oil and gas industries

Some BP440 steel armor plate, low-alloy high-strength steels have good atmospheric corrosion resistance. In some cases, appropriate precautions can be taken, and they can even be used without being coated in the atmosphere. The elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel and molybdenum. The excellent atmospheric corrosion resistance of some low-alloy high-strength steels has led to the formation of new concepts in the design of buildings, bridges and other structures, that is, these structures are constructed with appropriate exposed components of low-alloy high-strength steel.

Standing at a new historical starting point, we adapt to the requirements of supply side BP440 steel armor plate structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading BP440 steel armor plate steel materials supplier.

As the thickness and hardness of BP440 steel armor plate increase, the tendency to crack at the cutting edge increases. In order to prevent the BP440 steel armor plate from cutting cracks, preheating should be carried out before BP440 steel armor plate cutting. Special attention should be paid to preheating to make the entire BP440 steel armor plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole BP440 steel armor plate cannot be preheated, the partial preheating method can be used instead.

Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of BP440 steel armor plate, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.

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.
