Welded pipe production lineAccording to the use and production technology, it is roughly divided into scaffolding pipe, fluid pipe, line pipe, support pipe, guardrail pipe, etc. So, what is the main equipment of the welded pipe production line?
1. Loader frame
In order to meet the continuous production of welded pipe equipment, when preparing steel strip feeding and uncoiling, the reserved steel strip can be continuously transported out to make the welded pipe production line run continuously.
2. Make a prototype
The straight seam welded pipe forming machine is divided into longitudinal resistance roller type and longitudinal submerged arc welding forming. This is an important equipment of the forming machine welded pipe equipment production line.
3. Mold for welding
Welded pipe is the main vulnerable parts of welded pipe equipment production line. According to different manufacturing methods, the types of molds are divided into casting molds and forging molds. According to the process method, it can be divided into integral roll and combined type, and its quality directly affects the quality, output and cost of the product.
4. Welding equipment
Commonly used welding machine is divided into argon arc welding machine and ultrasonic welding machine. The welding part can be said to be an important process in the production line of stainless steel welded pipe equipment. Whether the welded pipe is welded or cracked. It may be caused by the operation error of the welding part.
5. Sizing machine
In the welded pipe equipment production line, the welded pipe unit can not only ensure the outer diameter of the welded pipe, but also improve the accuracy of the cross-sectional shape in the forming and welding production. The sizing pipe section is also one of the main components of the welded pipe equipment production line.
6. Cutting machine
The cutting machine realizes the high-precision fixed-length cutting of the welded pipe equipment in the running state. The cutting machine has hydraulic shear, grinding wheel shear, gas cutting and so on.
How to Quench and Tempere Straight Seam Welded Pipe
1, straight seam welded pipe surface quenching and tempering heat treatment generally adopts induction heating or flame heating. The main technical parameters are surface hardness, local hardness and effective hardening layer depth. The hardness can be measured with a Vickers hardness tester, a Rockwell hardness tester, or a Rockwell hardness tester. The choice of test force (oxide scale) is related to the depth of effective hardening layer and the surface hardness of longitudinal welded pipe.
2. Vickers hardness tester is an important means to determine the surface hardness of heat-treated longitudinal welded pipe in Hunan. The test force of 0.5~100kg can be selected to measure the surface hardening layer with a thickness as thin as 0.05mm. Its high precision, can distinguish the slight difference of surface hardness of heat treatment workpiece. In addition, since the depth of the effective hardened layer is also measured with a Vickers hardness tester, a large number of units that use surface heat treatment and Hunan longitudinal welded pipe must be equipped with a Vickers hardness tester.
3. When the parts require high local hardness, induction heating and other methods can be used for local quenching heat treatment.
