Reliable Spiral Weld Pipe Mill Consistent Quality Smooth Operation

The spiral welded pipe unit is a standard type unit developed and improved by DORCO Heavy Industry on the basis of absorbing the essence of foreign forming process technology and combining with the actual situation in China. It is the most competitive and mature unit with technical characteristics.
▶ Spiral welded pipe unit production process:
The raw materials are strip coil, welding wire, flux. They must pass strict physical and chemical inspection before they are put into operation.
Single or double wire submerged arc welding is used for butt butt of strip steel, and active submerged arc welding is used for repair welding after rolling into steel pipe.
Before forming, the strip is levelled, trimmed, planed, cleaned, transported and bent.
The electric contact pressure gauge is used to control the pressure of the cylinder on both sides of the conveyor to ensure the smooth transport of the strip steel.
Externally controlled or internally controlled roll molding.
The weld gap control device is used to ensure that the weld gap can meet the welding requirements. The pipe diameter, wrong side amount and weld gap are strictly controlled.
Both internal welding and external welding are performed by single wire or double wire submerged arc welding with Lincoln welding machine of the United States, so as to achieve stable welding quality and stability.
The steel pipe is cut into single pieces using an air plasma cutting machine.
Each batch of steel pipe shall undergo a strict inspection system to check the mechanical properties of the weld, chemical composition, fusion status, surface quality of the steel pipe and non-destructive testing to ensure that the pipe production process is qualified before it can be formally put into production.
▶ Automatic steel pipe hydraulic testing machine
Hydraulic testing machine is mainly used for welding pipe pressure test, with computer record, storage, printing, test results function. It has the advantages of high efficiency, high test pressure and strong safety. The pipe diameter range is Φ20-Φ3500mm, and the test pressure is 10-110MPa.
Process flow: up-tube - nozzle - water filling - pressure - pressure retaining - pressure relief - drainage - pipe out.
▶ Automatic flat head chamfering machine
Flat head chamfering machine is mainly used for flat head and groove processing on the end of welded pipe. Equipped with copying chamfering knife, the processing groove is uniform and beautiful. Our company provides steel pipe manufacturers with flat head chamfering machining range covering steel pipe diameter: φ20mm-φ3500mm, while meeting API-5L, API-5CT, BS1387-85, ASTM, GB9711 and other standards.
Process flow: tube - nozzle - clamping - flat head chamfering - loosen the fixture - pipe out
▶ Ultrasonic flaw detector:
Defects active alarm and spray mark, workers adjust parameters according to this;
The parts with continuous acoustic detection marks on the weld are re-examined by manual ultrasonic and X-ray;
Defects are repaired and will be nondestructive inspected again until the defects are confirmed to be cleared;
▶ X-ray steel pipe inspection:
The detection system is seamless with the whole production line, and ADAPTS to the control and management process requirements of steel pipe manufacturers. Automatic welding seam identification technology, convenient automatic control in the test preparation stage; With a database, the detection parameters of the same product can be automatically loaded with a key call; The whole system has a high degree of automation, operation and testing, and has a very high share in the domestic steel pipe production line.
▶ Spiral welded pipe unit application:
With efficient forming process and flexible adaptability, spiral welding pipe unit is widely used in high and low pressure fluid conveying pipe, pile pipe for urban construction, industrial structure pipe, power/heat/gas pipeline, etc., to provide efficient and high-quality pipeline solutions.
