Following the decline in crude steel production in the first ten days of this month, crude steel production rose again in the first ten days of this month. Inventories of heat preservation and anticorrosion pipe manufacturers and factories also declined. The production situation of secondary or steel plants is not clear. At present, as raw material prices continue to fall, consumer enterprises still have profit margins; coupled with financial pressure, most steel mills need to maintain operation in order to continue to obtain savings; therefore, steel mills still adhere to a higher start-up rate; Anshan region, for example, as of this month, Tangshan blast furnace start-up rate is about.0%, high production capacity application rate. Up to.0%, the rate of increase was normal.山东大鼎钢管厂、山东大鼎金属材料有限公司
物理性能试验6.1。国产无缝钢管按机械性能提供,普通碳素钢按GB/T700-88A级钢制造(但必须保证硫含量不超过0.050%,磷含量不超过0.045%),其力学性能应满足要求。ORM到GB表中指定的值。6.2、国内无缝钢管水压试验必须保证标准中规定的水压试验。
The vacuum carburizing temperature is generally higher than that of ordinary gas carburizing. Carburizing and diffusion are often used at 920~1040 C. As shown, there are two stages: pulse ventilation, stop gas, multi-stage carburizing and diffusion. The effect is better. Vacuum carburized layer is formed faster than ordinary gas, liquid and solid carburized layer because of its high temperature, especially its clean surface and high activity. If the carburized layer needs 1 millimeters, it will take 927 hours and 1 hours at 1033 degrees Celsius, only 5 hours.
Precision steel pipe has the advantages of no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, small cold bending deformation, high flatness, no cracks and so on. It is mainly used to produce pneumatic or hydraulic components. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe
The two or three to five layers of the matrix are separated from the upper part and the lower part, and centimeters, until the impregnation process is completed. After removing the groove, the excessive mixture on the adjacent inner surface of the substrate is scraped off, and the waterproof substrate formed between two or three to five layers forms the upper and lower parts of the formed semi-finished waterproof coil. The surface is of mulch material to make multilayer high efficiency waterproof film. Second World War, the development of the chemical industry, the drilling, production and transportation of oil and natural gas, all contributed greatly to refining.
