API 5CT Casing pipes ship construction use A131 DH36 structural steel supplied by BBN is mostly used in well structure building. Good quality API 5CT casing pipe could ensure well structure stability, isolate water and sand from tube working area, so drilling, oil production and other operations can be taken with no contamination. We can provide ship construction use A131 DH36 structural steel you conductor casing pipe, surface casing pipe, intermediate casing pipe, production casing pipe.
Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and ship construction use A131 DH36 structural steel resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, ship construction use A131 DH36 structural steel new materials, and promotes the competition of enterprises Struggle.
The ship construction use A131 DH36 structural steel steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the ship construction use A131 DH36 structural steel internal quality of the steel.
The microstructure of the quenched and tempered alloy steel, ship construction use A131 DH36 structural steel after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
