Product Details
This equipment adopts advanced forming and welding technologies to ensure precise pipe dimensions and firm welds. It is widely used in fields such as construction, furniture, automobiles, mechanical manufacturing, and fluid transportation.
It supports various cross-sectional shapes such as round tubes, square tubes, and rectangular tubes. By changing the molds, the production specifications can be quickly switched to meet diverse demands. The pipe diameter range is flexible and the wall thickness is adjustable to meet the standards of different industries.
The multi-pass roll forming technology is adopted to ensure uniform deformation of the steel strip and precise geometric dimensions of the pipe. Equipped with high-frequency induction welding (HFI) or TIG welding systems, the weld seams are smooth and have high strength. Quality can be guaranteed through online eddy current or ultrasonic testing. The PLC integrated control system realizes the full-process automation of feeding, forming, welding, sizing and cutting. It is easy to operate and highly stable. The touch screen human-machine interface enables real-time monitoring of production parameters and supports fault alarm and data recording.
Optimize the transmission structure to reduce energy consumption, and combine it with an efficient cooling system to extend the service life of the equipment. It can be optionally equipped with flying saw cutting or servo fixed-length cutting to reduce material waste and increase the yield of finished products. The key components are made of alloy steel and strengthened by heat treatment to adapt to high-intensity continuous operation. Modular design is convenient for maintenance and reduces downtime.
Typical applications: 1. Architectural decoration: stair railings, guardrails, steel structure frames. 2. Furniture manufacturing: Metal table and chair brackets, display shelves. 3. Industrial pipelines: Low-pressure fluid delivery pipes, ventilation pipes. 4. Automotive machinery: Drive shaft sleeves, hydraulic system components.
If you choose our steel pipe production line, the service support you will enjoy includes: equipment installation and commissioning, operation training and lifetime technical support. Production line configuration can be customized according to customer requirements.
