We have new cooperation projects with NNPC (Nigerian National Petroleum Corporation). Through tender, we got new order about oil tank plates for NNPC, and the tank plates will be used to build large oil tanks. This is not the first time we cooperated with NNPC, but it means much more to us than first time cooperation. It indicates our tank plates quality has been well recognized by Nigeria market.
BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December. Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.
API 5L Gr. A is mainly used for steel of large diameter pipeline. A709 grade 50W low alloy steel, API 5L Gr. A is mainly used for pressure liquid transportation, oil, natural gas, water and other liquid transportation, oilfield engineering, pipeline engineering, construction, steel pipe and oil and gas engineering using pipeline.A709 grade 50W low alloy steel
A709 grade 50W low alloy steel,In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe for there cable car supporter. Due to the special using of the pipes, they are very careful and servious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and proucts quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1400 tons pipe to us directly.
A709 grade 50W low alloy steel,Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar The hot rolled plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications Resulting shafts, axles, and gears can be used in the automotive industry and agriculture equipment A36 mild steel has good strength, formability, and excellent welding properties We also can supply welding, fabricating, and bending service,A709 grade 50W low alloy steel.
A709 grade 50W low alloy steel,40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785
Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, .
