cold drown pipe production process of hydranulic cylinder
Hydraulic cylinder body are main production high precision cold drawn tube was used as raw material, compared with the traditional production process, not only now the production of hydraulic cylinder speed, and save raw materials, high yield. Below to specific introduction of cold drawn pipe production process of hydraulic cylinder and the traditional distinction:
1, high efficiency: with the traditional method of producing a diameter of 420 mm, 12 meters long cylinder should be 154 hours, with the method of cold drawing production only 4 minutes.
2 high functions: due to the effect of rolling pressure head and the guide of the boring, in the process of cutting, the blank pipe due to the weight of the deflection, the rolling head deviate and boring cutter, cause waste. Functions only around 60%, and with cold drawn method production, functions can reach more than 95%.

3, high utilization rate of metal: made of traditional method of boring cylinder body, metal utilization only 50-70%. When using a method of drawing production, metal not only by cutting the end of the iron, it can get 30% extension of metal utilization rate can reach 95%.
4, can improve the mechanical properties of the finished tube metal: production by drawing method, make blank gets more than 30% of the plastic deformation, due to work hardening has greatly improve the strength of the finished tube metal limit.
Generally in the finished tube layer strength limit increase of 60%. High precision cold drawn pipe is made of seamless hot-rolled steel pipe, straight seam welded pipe as blank, after chemical treatment on the special cold drawing machine, through the special deformation principle of design of mould drawing, produce high precision tube. The dimensional accuracy of H10 ~ H8, straightness of 0.35 ~ 0.5 mm/m, the surface roughness Ra1.6-0.4.

Difference of PSL1 and PSL2(API 5L)
The API 5L has two standards, PSL1 and PSL2, which are very different from each other. I'll talk more about the differences between PSL1 and PSL2.
Production Process of Pipe Fitting
There are many kinds of processing methods for pipe fittings.
The Future of Steel Pipe Development
The future of steel pipe development is looking promising, according to expert analysis and data. The price of carbon steel pipe is predicted to bounce back this year, with China leading the way in increasing steel consumption demands. This is due to a series of government initiatives aimed at stimulating domestic demand, including the construction of affordable housing and infrastructure projects. The demand for structural steel pipe is also on the rise, thanks to state investment in housing and engineering projects. With private investment projects also gaining popularity, the steel pipe market is set to thrive in 2017.
