精密管近行情

精加工钢管的生产工艺与普通无缝钢管相同，是酸洗、冷轧多道次工序。产品可为粗铸件或冷件。2。精密钢管是近年来出现的产品，主要是内孔和外壁的尺寸具有严格的公差和粗糙度，外径较小。Jiangsu Shagang lowered the factory price of steel in the middle of this month, in which the price of heat preservation and anti-corrosion steel pipe was reduced by yuan and the price  Shagang has a certain benchmarking role in the heat preservation and anticorrosion steel pipe market, its price has been greatly reduced, domestic mainstream steel enterprises have introduced price
It can be said that, to a certain extent, this is because of excessive interference and other local power from the private interest, the steel industry not only delayed the transfer to the upstream of the industrial chain to achieve the goal, but also made the T overcapacity In this regard, the problem of overcapacity in the steel industry has not been alleviated. In essence, it should be a question of the relationship between power and market, whether the market should play a decisive role or not.

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.
