Multi - Specification Spiral Weld Pipe Mill Coil Width 1200 - 1600 Mm Price Advantage

The Duolek spiral welded pipe production line is the result of years of technological accumulation and improvement, integrating multiple advantages such as high automation, stable forming, energy saving and high efficiency, making it an ideal choice for modern large-scale pipe production. According to different production modes, this series of units is divided into two types: front swing (intermittent production) and rear swing (continuous production). The rear swing continuous production line is particularly suitable for fields that require high production efficiency and continuity, and is a key equipment for producing long-distance oil and gas pipelines.

The comprehensive performance advantages of this production line are outstanding:
Efficient production mode: The rear swing continuous production design avoids downtime and material waiting, achieving true uninterrupted production. Combined with space saving double swing bridge technology, the production efficiency is industry-leading.
Stable quality output: By establishing a strict inspection system, ensure that each process is qualified before entering the next stage. Combined with advanced welding technology and stable equipment foundation, the continuous stability of product quality is guaranteed.
A comprehensive quality assurance system: from physical and chemical inspection of raw materials entering the warehouse, to precision welding during the manufacturing process, and to non-destructive testing (ultrasonic, X-ray) of the final product, a closed-loop quality management chain is constructed.
Excellent equipment reliability: Key components are sourced from internationally renowned brands such as Lincoln welding machines and Siemens motors, laying a solid foundation for high performance, long lifespan, and low failure rates of the equipment.
With its flexible production configuration and excellent product quality, Duoleke Spiral Welded Pipe Production Line is committed to providing reliable products and technical support to customers in various industries around the world.

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 pipe diameter range is from Φ 20 to Φ 3500mm, and the test pressure is 10-110MPa.
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 machine processing range for steel pipe production enterprises, covering steel pipe diameters ranging from 20mm to 3500mm, while meeting standards such as API-5L, API-5CT, BS1387-85, ASTM, GB9711, etc.
Release 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;
