Do you want to know more about precision seamless steel tube ?

There are many types of seamless steel pipes. The precision seamless steel pipe alone is divided into many types. From the types, there are also major Variety, delivery condition and so on, let's find out more!

1.Classification:

Precision seamless steel pipe, precision hydraulic seamless steel pipe, cold drawn precision seamless steel pipe, cold rolled precision seamless steel pipe, high precision seamless steel pipe, precision bright seamless steel pipe. The specifications range from φ3 × 0.4 to φ120 × 12, the accuracy can reach ± 0.025, and the roughness (Ra) can reach 1.6-0.8-0.2. Stainless steel honing tubes for precision honing tubes and extruded tubes for cylinders and hydraulic cylinders. It can also produce thick and thin special-shaped tubes with various complex cross-section combinations, straight and internal toothed tubes, and spiral toothed tubes. And special-shaped tubes with different longitudinal diameters and wall thicknesses.
