Chemical heat treatment is to heat the workpiece containing carbon, nitrogen and other alloy elements in the medium (gas, liquid, solid) for a long time, so that the surface of the workpiece to form carbon, nitrogen, boron, chromium and other elements. After infiltration, some other heat treatment processes, such as quenching and tempering, are sometimes needed. The main chemical heat treatment is carburizing, nitriding and metallization.
It is precisely because of the emergence of seamless steel pipe that these high-pressure gas and liquid transportation problems have been solved, so that people can really make life so fast and convenient. Many factories have expanded the scale of production, and seamless steel tubes, like factories, have been used for high transportation.

Oil quenching causes surface deterioration easily. Due to the high surface activity, significant thin layer carburization can occur under the action of short and high temperature oil film. In addition, the adhesion of carbon black and oil on the surface is not conducive to simplifying the heat treatment process. The development of vacuum quenching technology mainly lies in the development of single gas cooled quenching furnace with excellent performance. Double chamber furnace can also be used for gas quenching (front chamber air jet cooling), but the operation of the two stations makes it difficult to load a large number of furnace, and easy to cause workpiece deformation or change the direction of workpiece quenching. NG deformation during high temperature movement.
山东大鼎钢管厂公式计算钢管的理论重量：W=(D-S)＊S＊0.02466，其中W=钢管每米的重量；S=钢管的公称壁厚；D=钢管的公称外径，光亮管的表面质量i清洁、无氧化层、无裂纹、折叠、轧制、结疤、分离层和条纹。
According to a series of formulas, the theoretical weight of steel pipe is calculated: W=(D-S)*S*0.02466, in which W=the weight of steel pipe per meter; S=the nominal wall thickness of steel pipe; D=the nominal outer diameter of steel pipe; the surface quality of bright pipe I is clean, oxide-free, crack-free, folding, rolling, scarring, separating layer and stripe.
山东大鼎钢管厂产品按标准及用户要求销售：GB/T8162-2008（结构管）、GB/T8163-2008（流体管）、GB/T3087-2008（低压锅炉管）、GB/T5310-1995（高压锅炉管）、GB/T17396-1999（液压管）。IC支撑管)GB/T6479-2000(专用化肥管)，GB/T3639-2000(冷拔或冷拔或专用化肥管)。冷轧精密无缝钢管等。本厂销售部管理成都、包钢、冶炼钢、卢宝、鞍钢、无锡、西宁、衡阳、洪都、天津等大型钢铁厂生产的各种无缝钢管和合金管。库存10000多吨，900多个规格，常用材料：10_、20_、35_、45_、20G、16Mn、Q345B、27SiMn 35CrMo、42CrMo、40Mn2、20Cr、40Cr、10CrMo910、15CrMo、12Cr1MoV、15CrMoG、12Cr1MoVG、T91、1Cr5Mo等。
山东大鼎钢管厂The large stress and force at the upper yield point decrease firstly before yielding, and the lower yield point (_sl): the small stress at the yield stage is independent of the initial instantaneous stress. The yield point formula is: formula: FS yield strength (constant) in tensile test, N (Newton) SO original cross-section area, MM2. Fracture elongation (Sigma) In tensile tests, the percentage increase in the standard distance 山东大鼎金属材料有限公司between the specimens and the original standard distance is called elongation. The average daily capacity of copper in a year is expressed in sigma, with a unit of%. The formula is: Type: gauge length of L1 - after fracture, mm, L0 - original gauge length, mm. Section shrinkage山东大鼎钢管厂冷拔无缝钢管具有内外壁无氧化层、高压无泄漏、精度高、光洁度高、冷弯不变形、平整无裂纹、表面防锈处理等特点。主要用于汽车、摩托车的机械结构、液压设备和气动或液压元件。冷拔无缝钢管生产的工业控制包括模具设计、退火、酸洗、润滑等条件。同时，要搞好毛管质量检查和维修工作。
