Drilling and cutting of S690QL steel equivalent to grade 50

The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.

The service temperature of high pressure seamless steel pipe is below 450 ℃, and the domestic pipes are mainly made of S690QL steel equivalent to grade 50, No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the pipe will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.

With the experienced staff in the steel industry, BBN steel specializes in steel deep processing service. We provide access to best-in-class processing for steel plates, steel pipe and tubes, including laser cutting, saw cutting, bending, welding, drilling, grinding and more, to give our customers the products they need in exactly the way they need them

10CrMo9-10 seamless pipe implements European standard EN 10216-2. The chemical composition of 10CrMo9-10 seamless pipe: C 0.08-0.14, Si ≤ 0.50, Mn 0.30-0.70, P ≤ 0.025, S ≤ 0.020, Cr 2.00-2.50, Ni ≤ 0.30, Mo 0.90-1.10, Al ≤ 0.04, Cu ≤ 0.03. The mechanical properties of 10CrMo9-10 seamless pipe: tensile strength: 450-530 MPa, yield strength: ≥ 280 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. S690QL steel equivalent to grade 50, 10CrMo9-10 seamless pipe is a kind of high temperature and high pressure boiler steel, which is mainly used in the production of power station boiler, steam boiler equipment, pressure vessel, large pressure pipe, etc.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the S690QL steel equivalent to grade 50 steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
