API 5L X42 steel plate/pipes for large diameter pipes X42 steel plate/pipes, API 5L X42 steel plate/pipes, under API 5L standard, we can regard X42 steel plate/pipes as large diameter pipes. quenched and tempered GL-E40 hull steel plate, X42 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X42 steel used for pressure liquid transport, oil, gas, water and other liquid transportation, oilfield engineering, ductwork, construction, steel pipe and oil and gas project which use pipes.
Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel quenched and tempered GL-E40 hull steel plate and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.
Superior process production line advantage sdf: The company has focused on weathering steel quenched and tempered GL-E40 hull steel plate, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.
With the increase of temperature, the yield limit of quenched and tempered GL-E40 hull steel plate will decrease monotonically, but the tensile strength of quenched and tempered GL-E40 hull steel plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of quenched and tempered GL-E40 hull steel plate. Near the blue brittleness temperature, the quenched and tempered GL-E40 hull steel plate strength increases and the plasticity decreases. The elongation and section shrinkage of quenched and tempered GL-E40 hull steel plate increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
