Spiral welding pipe equipment

Spiral welded pipe equipment have different functions, the sophistication of the equipment determine the quality of the steel pipe to a certain extent.
Impact testing machine: the impact testing machine into manual Charpy impact test machine, semi-automatic impact testing machine, non-metallic impact testing machine. It is an instantaneous measurement and the recording material by the impact process, the characteristic curve of a new type impact testing machine. Charpy and Izod tests of the two forms can be achieved by replacing the base of the pendulum and the specimen. It does this by detecting the angular displacement signal to the computer for data processing, high precision.
Online Ultrasound: weld aspect to defect detection, heat-affected zone stratified detection and burr height control, mainly used for the production of process control. For fast production speed, configuration, defect tracking spraying device to ensure 100% detection of weld and within burrs. Tracking and resection. Online flattening and do weld pressure angle of 0 degrees and 90 degrees of flattening test: According to the characteristics of raw materials and production, sampling, and to protect the pipe, the basic performance requirements.
Hydrostatic test: the base metal and weld tubes to provide the compactness protection.
Off-line weld ultrasonic testing: for hydrostatic testing steel pipe welds aspect to the defect inspection.
Manner molding angle adjustment can be divided into: the forward swing, after tilting;
According to the molding machine feed can be divided into: on a roll, the next roll; (next roll now more commonly used on roll only on special occasions)

Continuous adjustment of the production of the molding machine molding methods can be divided into: The volume roll-bed-type molding machine, the sliding friction sleeve molding machine, sets of roller joint molding machine, full rolling friction roller cover molding machine and PRD invention the diameter of the PRD molding machine.
