API 5L Cold Drawn Carbon Seamless Steel Pipes Seamless Hydraulic Tube

All kinds of alloy pipes 16Mn, 27SiMn, 15CrMo, 35CrMo, 12CrMov, 20G, 40Cr, 12Cr1MoV, 15CrMo steel pipes are divided into seamless steel pipes and welded steel pipes according to different production processes. Seamless steel pipe is a seamless steel pipe made of perforated ingots, billets or steel bars.

1. Various components of hydraulic transmission can be arranged conveniently and flexibly according to needs.

2. Light weight, small volume, small inertia and fast reaction speed.

3. It is easy to operate and control, and can realize stepless speed regulation in a wide range (speed regulation range reaches 2000:1).
