Product Description

Product Description

Smaller outside diameter.
High precision can be used for small batch production
The cold-drawn finished product has high precision and good surface quality.
The cross area of steel pipe is more complex.
The performance of steel pipe is superior and the metal is dense. 1. Manufacturing method
According to different production methods, it can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extruded pipe, etc.
Hot-rolled seamless pipe is generally produced on the automatic pipe rolling mill. After inspection and removal of surface defects, the solid tube blank is cut to the required length, centered on the end face of the piercing end of the tube blank, and then sent to the heating furnace for heating and perforated on the piercing machine. At the same time, the piercing continues to rotate and move forward. Under the action of the roll and the plug, a cavity is gradually formed inside the tube blank, which is called the capillary. Then it is sent to the automatic pipe rolling mill to continue rolling. Finally, the wall thickness of the whole machine is uniform, and the diameter is determined by the sizing machine to meet the specification requirements. It is an advanced method to produce hot rolled seamless steel pipe by continuous pipe rolling mill.
In order to obtain seamless pipes with smaller size and better quality, cold rolling, cold drawing or both methods must be adopted. Cold rolling is usually carried out on a two-high mill, and steel pipes are rolled in a circular pass formed by a variable cross-section circular groove and a fixed conical plug. Cold drawing is usually carried out on 0.5~100T single-chain or double-chain cold drawing machine.
The extrusion method is to put the heated tube blank into the closed extrusion cylinder, and the piercing rod and the extrusion rod move together to extrude the extruded part from the smaller die hole. This method can produce steel pipes with smaller diameter.

product application

Seamless pipes are widely used. Seamless pipes for general purposes are rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for conveying fluid.
Supply is divided into three types according to different purposes: a. Supply according to chemical composition and mechanical properties; B. Supply according to mechanical properties; C. Supply according to hydraulic test. The steel pipes supplied according to category a and b shall also be subjected to hydraulic test if they are used to bear liquid pressure.
There are many kinds of seamless pipes for special purposes, such as boiler seamless pipes, geological seamless pipes and petroleum seamless pipes.
