We have new significant quenched and tempered GL-E40 hull steel plate projects in Nigeria. It is about crude oil storage tanks. With the development of our steel materials business in the Africa those years, Nigeria has been an important market to us. And we have many quenched and tempered GL-E40 hull steel plate famous projects in local and also participated in a lot of governmental projects. This crude oil storage tanks project is a very big engineering, and lasts for years. This is the only initial stage. We are under negotiation about following installation and further demands etc. matters.
After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with us
Pipeline steel refers to a type of steel with special requirements used for the transportation of oil, natural gas and other pipelines. Depending on the thickness and subsequent formation, pipeline steel can be produced by hot continuous rolling machines, furnace coil machines or plate machines, and formed into large-diameter steel pipe by spiral welding or UOE straight seam welding. The current development trend of quenched and tempered GL-E40 hull steel plate pipeline engineering is large-diameter, high-pressure rich gas transportation, high cold and corrosive service environment, and thickening of submarine pipelines.
As per JIS G3101 standard, the Carbon (C), Silicon (Si) and Manganese (Mn) content of SS400 steel plate are not controlled. Phosphorus (P) content of quenched and tempered GL-E40 hull steel plate, JIS SS400 steel plate is 0.050% Max and Sulphur (S) content is 0.050% Max. The SS400 steel melting point is 1430 Degree Celsius, Brinell Hardness is 160HB, density is 7.85g/cm3, Young’s Modulus is 190-210Gpa. The strength and elongation of JIS SS400 steel plate varies with thickness. Generally, the tensile strength of SS400 steel plate is 400-510 Mpa. Elongation is above 21%. Yield strength ≥245Mpa for thickness≤16mm. When the JIS SS400 steel plate is thciker than 100mm, the yield strength shall not less than 205Mpa.
In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our quenched and tempered GL-E40 hull steel plate quality. Till now, we keep exporting around 100 tons per month as regularly.
we are the best professional steel manufacturer in China. We can supply kinds of steel product size，if you want to purchase steel plate or steel pipe and other products. Please contact us freely. we can give you the quenched and tempered GL-E40 hull steel plate best price with high quality.
