The metal corrugated tube billet is divided into two kinds: seamless tube billet and seamless tube billet.
Seamless tube billet manufacturing, according to different raw materials.Different processes are used for manufacturing.Material plus factory can provide the long stainless steel thin wall seamless tube with wall thickness of 0.1-0.3mm and outer diameter of 0.10-60mm.This seamless tube with high finish,
However, the wall thickness tolerance is large (+/-0.03mm), which is generally used to make spiral corrugated tubes and annular corrugated tubes with low performance requirements.The metal bellows production plant can use standard thin-walled tubes of 0.8~1mm thick metal sheet (strip) or 0.5~1mm thick wall.
After several deep drawing or spinning drawing process to manufacture various specifications of corrugated tube blank.This process can produce blank with high surface finish, small tolerance of wall thickness (<=+/-0.005mm) and short length, which can be used to produce corrugated pipe with high requirements.
The manufacture of seamless tube blank is usually made of the required thickness of the plate or strip.The quality of the tube billet depends directly on the quality of the plate (strip) and welding.Generally speaking, its wall thickness tolerance
Easier to control.
1.Multiple thinning and drawing processes
The multiple thinning drawing process is applicable to the corrugated pipe billet whose length is less than 300mm. The process mainly includes blanking, multiple drawing, multiple heat treatment and multiple thinning drawing.
1.Steel ball spinning and thinning drawing manufacturing process and equipment
The spinning of steel ball is a process of drawing and thinning under high speed rotation of blank.The high speed rotation of the punch (or die) drives the ball itself to rotate along the blank perimeter
With high speed rotation, the material deforms under the action of positive force and tangential force when the blank is fed by axial feed on the die.
2..Welding pipe blank manufacturing process
The manufacture of corrugated pipe blank by welding is a process method with high production efficiency, low cost, easy control of wall thickness and strong adaptability.At present, it is mainly used for manufacturing large diameter corrugated pipe blank and hose blank.
