山东大鼎金属材料有限公司The main characteristics of precision seamless steel pipe in precision steel pipe mill are: high precision, high inner and outer wall finish, no oxide layer after heat treatment, high inner wall cleanliness, high pressure bearing, cold bending deformation, flattening, no crack. It can be used for all kinds of complex deformation and machining. Steel tube color: bright white medium, high metallic luster. Precision seamless steel pipe process: high quality carbon steel, finish rolling, non-oxidizing bright heat treatment state, non-destructive testing, steel pipe inner wall with special equipment cleaning, high pressure flushing, rust-proof oil coated on the steel pipe, used for rust prevention. When installing, two end covers are used for dust prevention.山东大鼎钢管厂石油裂化用无缝钢管（GB9948-88）是适用于石油精炼厂的炉管、热交换器和管道无缝钢管。7.地质钻探用钢管（YB235-70）是供地质部门进行岩心钻探使用的钢管。8.金刚石岩芯钻探用无缝钢管（GB3423-82）是用于金刚石岩芯钻探的钻杆、岩心杆、套管的无缝钢管。
山东大鼎钢管厂A set of equipment can be used for pipeline insulation: steel pipe shot peening and rust removal, ternary PE winding equipment, SIMN seamless PE pipe black and yellow jacket pulling machine, sand blasting and rust removal equipment, polyurethane low-pressure tendering, foaming platform, GL donkey fiber reinforced plastic winding machine, two-layer PE coating, cement mortar spraying machine and other anti-corrosion and insulation test equipment. In the tensile test, the ratio of the large reduction of the cross-section area to the original cross-section area when the specimen shrinks is called the cross-section shrinkage.

The ability of metal materials to resist indentation of hard objects has a small circumference/area ratio on all geometric sections, i.e., large internal sections can be obtained with the same number of materials. Because of its low cost and high strength, steel pipe has been widely used in modern fluid transportation. According to the different production process, the steel pipe is divided into seamless steel pipe and welded steel pipe, they are divided into high frequency longitudinal welded pipe (ERW), spiral welded pipe (SSAW), submerged arc welded pipe (UOE) and so on. In the past, traditional seamless pipes were used for fluid pipelines.山东大鼎钢管厂
精密钢管是冷拔或热轧后的一种高精度钢管材料。精密钢管主要用于生产气动或液压元件，如气缸或气缸的产品，它们可以是无缝的或焊接的，但大多数是精密无缝钢。管。精密钢管具有尺寸精度高、表面光洁度高、热处理后管内外表面无氧化膜、管材无压扁裂纹、冷弯变形、耐高压、能进行各种复杂变形和机械加工等优点。深加工。主要生产钢管牌号：10, 20, 35、45、40Cr、42CRMO等。精密钢管；GB/T699—2008；GB/T3639－2008。
