1.What is seamless steel pipe?

Stainless steel seamless pipe is a kind of long steel with hollow section and no seams around.

2.Features of stainless steel seamless pipe

First, the thicker the wall thickness of the product is, the more economical and practical it is. The thinner the wall thickness is, the higher the processing cost will be; 


Secondly, the process of the product determines its limited performance. Generally, the seamless steel pipe has low precision: uneven wall thickness, low brightness of the inner and outer surface of the pipe, high cost of sizing, and there are pits and black spots on the inner and outer surface that are difficult to remove;


Third, its detection and shaping must be offline. Therefore, it shows its advantages in terms of high pressure, high strength and mechanical structure materials.

3.Type of seamless steel pipe

1. Seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extruded pipe according to different production methods.

 

2. According to the shape classification, there are circular tubes and special-shaped tubes. In addition to square tubes and rectangular tubes, special-shaped tubes also have ellipses

 

Pipe, semicircular pipe, triangular pipe, hexagonal pipe, convex pipe, quincunx pipe, etc.

 

3. According to different materials, it can be divided into ordinary carbon structural pipe, low alloy structural pipe, high-quality carbon structural pipe

 

Metal structure pipe, stainless steel pipe, etc.

 

3. According to the special purpose, there are boiler tubes, geological tubes, petroleum tubes, etc.

4. Use of seamless steel pipe

1. Seamless pipes are widely used. Seamless pipes for general use are made of ordinary carbon structural steel, low alloy structural steel or Rolled alloy structural steel, with the largest output, is mainly used as pipeline or structural parts for conveying fluid.


2. According to different uses, it can be supplied in three categories: a. according to chemical composition and mechanical properties; b. Supply according to mechanical properties; c. Supplied as per hydrostatic test. The steel pipes supplied according to class a and b shall also undergo hydrostatic test if they are used to withstand liquid pressure.


3. Seamless tubes for special purposes include boiler seamless tubes, geological seamless tubes and petroleum seamless tubes.

5.Manufacturing method

According to different production methods, it can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extruded pipe, etc.

1. Hot rolled seamless tubes are generally produced on automatic tube rolling mills. The solid tube blank is inspected and the surface defects are removed,Cut it to the required length, center it on the end face of the piercing end of the tube blank, then send it to the heating furnace for heating, and then pierce it on the piercing machine Holes. In the process of piercing, the continuous rotation and advance, and under the action of the roll and the plug, the inner space of the tube blank gradually forms Cavity, called capillary. Then it is sent to the automatic pipe mill to continue rolling. Finally, the wall thickness is adjusted by the homogenizing machine, and the wall thickness is adjusted by the sizing machine Calibrate to meet the specification requirements. It is an advanced method to produce hot rolled seamless steel pipe by continuous pipe rolling mill.


2. To obtain smaller and better quality seamless tubes, cold rolling, cold drawing or a combination of both must be used Method. Cold rolling is usually carried out on a two high mill. The steel pipe is in a variable cross-section circular hole groove and a fixed conical plug The formed annular pass is rolled. Cold drawing is usually carried out on 0.5~100T single chain or double chain cold drawing machine that 's ok.


3. The extrusion method is to place the heated tube blank in a closed extrusion cylinder, and the piercing rod and the extrusion rod move together,Extrude the extrusion from the smaller die hole. This method can produce steel pipes with smaller diameters.
