Analysis of the core equipment of DUOLEK spiral welded pipe production line!

An efficient and reliable spiral welded pipe production line not only relies on precision forming and welding hosts, but also on a series of powerful auxiliary equipment.
These devices are mainly responsible for end face precision machining, quality inspection, and performance testing of formed welded pipes, which is a key guarantee to ensure that the final product fully meets strict industrial standards in terms of dimensional accuracy, end face quality, pressure bearing capacity, and internal integrity. They together constitute an indispensable finishing and quality inspection process in automated steel pipe production.
Fully automatic steel pipe hydrostatic testing machine
The hydraulic testing machine is mainly used for pressure testing of welded pipes, and has the functions of computer recording, storage, printing, and test results.
It has the advantages of high efficiency, high testing pressure, and strong safety.
The range of pipe diameter is from 20 to 3500mm, and the test pressure is 10-110MPa.
Process flow: upper pipe - connecting pipe - water filling - pressure pressing - pressure holding - pressure relief - drainage - outlet pipe.

Fully automatic flat head chamfering machine:
The flat head chamfering machine is mainly used for flattening and chamfering the ends of welded pipes. Equipped with a contour chamfering knife, the processed groove is uniform and beautiful. Our company provides flat head chamfering machines for steel pipe production enterprisesProcessing range covers steel pipe diameter:
φ20mm-φ3500mm, Simultaneously meet standards such as API-5L, API-5CT, BS1387-85, ASTM, GB9711, etc.
Process flow: upper pipe - connecting pipe - clamping - flat head chamfering - releasing fixture - outlet pipe

Ultrasonic flaw detector:
Take the initiative to alarm and spray marks if there are shortcomings, and workers adjust parameters accordingly;
The parts with continuous ultrasonic testing marks on the weld seam shall undergo manual ultrasonic and X-ray re inspection again;
Defects will be repaired and undergo non-destructive testing again until they are confirmed to be cleared;

X-ray steel pipe inspection:
The detection system seamlessly integrates with the entire production line, adapting to the control and management process requirements of steel pipe manufacturers.
Welding seam automatic recognition technology facilitates automatic control during the preparation stage of inspection; With a database, the detection parameters of the same product can be automatically loaded with just one click, and the entire system has a high degree of automation.
