Hot Rolled seamless steel pipe

- Apr 17, 2019-

What is the excellence between truth seamless steel tube and seamless steel tube?The distinction between exactness steel tube and seamless steel tube is as follows:

1, the foremost feature of seamless steel tube isn't any fastening seam, can set about to larger pressure.The product might even be very rough solid or cold drawn.

2, truth steel pipe could also be a product in recent years, within the main the inner hole, the outer wall size has strict tolerance and roughness.Features of cold-drawn truth steel tube:Smaller outside diameter.2. High truth can do small batch production

3. The cold-drawn product has high truth and sensible surface quality.

4. The cross area of steel tube may be a ton of advanced.

5. The steel tube has higher performance and dense metal.Difference: once hot rolling truth steel tube hot rolled exactness tube with the block or block continuous casting spherical billet as a stuff, 

by step heating chamber, atmospheric state water descaling once returning into the roughing mill, roughing expected by the cutting head, tail, thus into the finishing mill, and conjointly the implementation of computer management rolling and finishing once through bedded cooling and also the winder, become straight hair volume.The head of straight hair coil, tail usually shows tongue type and decelerate form, thickness, breadth accuracy is poorer, 

edge usually exists wave, fold edge, tower sort anticipate blemish.Its coil weight is relatively serious, and conjointly the inner diameter of the steel coil is 760mm.

The straight hair coil through the top, the tail, the sting and conjointly the multi-pass straightening, leveling and completely different line treatment, then cut plate or rewinding, that is:

 hot rolled plate, flat hot rolled steel coil, longitudinal cut belt and completely different product.Hot - rolled finishing coils will become hot - rolled pickling coils if they're pickling,

 rinse and oiled.Main kinds of truth seamless tubes: DIN series exactness precision bright precision seamless tubes, mechanism for truth seamless tubes, automotive manufacturing truth seamless tubes
