At present, the design of oil and gas CCS F32 hull steel plate pipeline is based on the yield strength of steel, and high transmission work requires higher yield strength of CCS F32 hull steel plate steel. For welded wire pipe, the yield strength decreases after rolling and decreases with the increase of strength.
In recent years, in line with the development trend of iron and CCS F32 hull steel plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which CCS F32 hull steel plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
As the thickness and hardness of CCS F32 hull steel plate increase, the tendency to crack at the cutting edge increases. In order to prevent the CCS F32 hull steel plate from cutting cracks, preheating should be carried out before CCS F32 hull steel plate cutting. Special attention should be paid to preheating to make the entire CCS F32 hull steel plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole CCS F32 hull steel plate cannot be preheated, the partial preheating method can be used instead.
CCS F32 hull steel plate, 45# steel is widely used in mechanical manufacturing, and its mechanical properties are very good. But 45# steel is a kind of medium carbon steel, the quenching property is not good, 45# steel can be hardened to HRC42 ~ 46. Therefore, if the surface hardness is required, and the superior mechanical properties of 45# steel are expected to be exerted, the surface of 45# steel is often carburized and quenched, so that the required surface hardness can be obtained.
Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
