Precision Seamless Pipe
Precision seamless pipe is a pipe material producing by a cold drawn process with high precision and high-quality finish. Due to the characteristics of high-precision, in precision machinery manufacturing, auto parts, hydraulic cylinders, construction (steel sleeve) industry has a very wide range of applications.
Characteristics of precision seamless pipe
1. high precision, saving the loss when the quantity of machining users.
2. specifications, a wide range of applications.
3. cold-rolled finished products, high precision, good surface quality and straightness.
4. steel pipe inner diameter can be made hexagonal.
5. steel pipe superior performance, the metal is relatively dense.
