In terms of service, our service is a "one-stop" way of working. We have our own ABS EH40 container ship steel processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as ABS EH40 container ship steel cutting, welding, drilling, galvanizing, etc., at the lowest cost.
Heat-resistant steel has good oxidation resistance, corrosion resistance and tissue stability. The thermal strength performance is high, and the ABS EH40 container ship steel process performance is good. Heat-resistant steel plates and sheets are commonly used in the manufacture of parts that work at high temperatures in industrial sectors such as boilers, steam turbines, power machinery, industrial furnaces, and aviation and petrochemical industries.
The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product ABS EH40 container ship steel more than 15 years.
In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and ABS EH40 container ship steel pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
