1. Industrial seamless steel pipes are made of stainless steel pipes, which are cold drawn or cold rolled and then pickled to produce finished stainless steel seamless pipes. The characteristics of industrial stainless steel seamless pipes are that they have no welds and can withstand greater pressure. The surface of the steel pipe can be bent and reamed through solution bending (which is what we usually call the annealing process).
2. In recent years, precision seamless steel pipe products are mainly made of holes, with strict outer wall dimensional tolerance requirements and high requirements for steel surface finish. In addition, precision seamless steel pipes also have the following characteristics: 1. Small pipe diameter. Generally speaking, the diameter of precision seamless steel pipes is generally greater than 6mm. 2. High precision and can be produced in small batches.
3. The precision of precision seamless steel pipe is relatively high. The inner diameter of the steel pipe is 6 to 60, and the outer diameter tolerance is generally controlled within plus or minus 3 to 5 wires.
4. The precision seamless steel pipe has good surface finish, the inner and outer surface finish of the pipe is Ra≤0.8μm, and the wall thickness can be up to 0.5mm. Then the internal and external surface finish of the polished tube can reach Ra≤0.2-0.4μm (such as mirror surface).
5. The steel pipe has superior performance, the metal is relatively dense, and the pressure that the steel pipe can withstand increases. Taken together, precision seamless steel pipes are deeply processed in ordinary industrial grade stainless steel pipes. They have obvious advantages in precision and smoothness, but the cost is higher and they are high-end stainless steel pipes.
Electropolished (EP) Seamless Tube
Electropolished Stainless Steel Tubing is used for biotechnology, semiconductor and in pharmaceutical applications. We have our own polishing equipment and produce electrolytic polishing tubes that meet the requirements of various fields under the guidance of the Korean technical team.
