The difference between precision steel tube and seamless steel tube

Views:72     Author:Site Editor     Publish Time: 2018-09-21      Origin:Site

The main feature of seamless steel tubes is that they have no weld seams and can withstand large pressures. The product can be used for product is very rough cast or cold-draw.

Precision steel pipes are products that have appeared in recent years, mainly due to strict tolerances and roughness of inner and outer wall sizes.

Cold drawn precision steel pipe features:

1). The outer diameter is smaller.

2). High precision can be produced in small batches.

3). The cold drawn product has high precision and good surface quality.

4). The cross-sectional area of the steel pipe is more complicated.

5). The performance of the steel pipe is superior and the metal is dense.

Changzhou Raymond precision steel tube is specialized in cold drawn precision seamless steel tube and cold rolled seamless steel tube for more than 17 years experience.

Most our cold rolled seamless steel tube is used for shock absorber, gas spring, automotive spare parts, precision tools etc.

Most our cold drawn seamless steel tube is used for bushing, heat exchanger and condenser, sleeve etc.

Material: 1010, A53-A, St37-2, C10,CK10, STKM11A, STKM12A, STKM13C etc.

               1020, STB42, A106-B, St45-8, C22,CK22, STKM12B, STKM13A etc.

               1045, C45,CK45, CC45 etc.

               30CrMo, 4130.

               16Mn, STS49, St52.4, St52 etc.

Below are pictures of our cold rolled precision seamless steel tube and cold drawn precision seamless steel tube.


Hot rolled precision steel pipe

The hot-rolled precision steel pipe is made of continuous casting round billet slab or initial rolled slab as raw material, heated by step heating furnace, descaled by high pressure water and then into rough rolling mill. The rough rolling material passes through the cutting head and tail and then enters the finishing mill. The computer controlled rolling is carried out, and after the final rolling, the laminar cooling and the coiler are taken up to become a straight hair roll. The head and tail of the straight hair roll tend to be tongue-shaped and fish-tail-shaped, and the thickness and width are poorly accurate. The edge often has defects such as a wave shape, a folded edge, and a tower shape. The weight of the coil is heavier and the inner diameter of the coil is 760 mm. After straightening the straight hair through the cutting, cutting, trimming and multi-pass straightening, leveling and other finishing lines, and then cutting or rewinding, it becomes: hot-rolled steel sheet, flat hot-rolled steel coil, vertical Cutting tape and other products. Hot-rolled finishing rolls are hot-rolled and pickled if they are pickled to remove oxide scale and oiled.

So, before you order pipes, please confirm below questions:

1. What place pipes will be used for?

2. Size and other requirements.

3. How will you do after you receive pipes?

If you have any questions, please feel free to contact us in any time.
