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 is carbon, silicon, silicon, manganese, sulphur, phosphorus, phosphorus and chromium. The cold deformation processing of precision steel pipe in Wuxi, and the effect is not good. The head and tail of straight curly hair are usually tongue shaped and fishtail, with poor accuracy in thickness and width. It often has wavy, folded edges, and tower shaped edges.
天津市场高压无缝管价格稳定。据了解，昨日市场业务交易可以接受，下游采购正常，大宗出货2000多吨。由于市场存货的明显下降，商家的销售压力不大，因此维持稳定的需求较高。目前，天津市库存水平较低，下游需求仍可接受，商家出货情况较好，高压无缝管市场价格有望稳定和下降。本周高压无缝管市场处于紧绷状态。虽然大户库存仍处于稳定水平，但出货量和出货积极性相对较弱，后期市场形势十分严峻。预计高压无缝钢管报价将在下周大幅调整，整体看跌。

Domestic pipes are mainly made up of hot rolled or cold drawn and root carbon welded pipes. Precision tubes are usually used under high temperature and high pressure conditions. When pipes are used as boiler tubes for high temperature flue gas and steam, they will be oxidized and corroded. The steel pipe is required to have high durability, high oxidation resistance, corrosion resistance and good microstructure stability. According to the high temperature performance of boiler tubes, the boiler tubes are divided into common boiler tubes and high-pressure boiler tubes. General boiler tubes or high pressure boiler tubes can be divided into various types of pipes according to their needs.高压锅炉用无缝钢管（GB5310-2008）是用于制造高压及其以上压力的水管锅炉受热面用的优质碳素钢、合金钢和不锈耐热钢无缝钢管。5.化肥设备用高压无缝钢管（GB6479-2000）是适用于工作温度为-40~400℃、工作压力为10~30Ma的化工设备和管道的优质碳素结构钢和合金钢无缝钢管。精密管制造方法一般精密管在350℃以下使用。
