Production process
Raw Material Preparation
Select high-quality steel strips, conduct material inspection, and uncoil them for further processing.
Production Process
Forming
Feed steel strips into the forming machine, which gradually bends and shapes them into a spiral tube through a series of rollers.
Production Process
Welding
Employ automatic welding equipment to continuously weld the edges of the spiral tube, ensuring a strong and seamless joint.
Production Process
Calibration and Straightening
Adjust the diameter and shape of the welded pipe to meet specified standards, and straighten it to eliminate any curvature.
Production Process
Cutting
Cut the continuous pipe into required lengths according to project needs.
Production Process
Quality Inspection
Carry out strict inspections, including non-destructive testing, dimensional measurement, and pressure testing, to ensure compliance with international quality standards.
Production Process
Surface Treatment
Apply anti-corrosion coatings or other surface treatments to enhance the pipe’s durability and performance.
Production Application
Footwear abrasion solutions
1. Petroleum and Natural Gas: Used for long-distance transmission trunk lines and offshore platforms. With high strength and pressure resistance, it ensures transportation safety and can withstand complex marine environments.
2. Municipal Engineering: Serves as the main pipeline for urban water supply, meeting the demand for large-diameter water transportation. Applied to drainage and sewage networks, its smooth inner wall prevents blockages, and corrosion resistance extends its service life.
3. Energy and Power: For cooling water transportation in nuclear power plants and thermal power plants, it can withstand high temperature, high pressure, and large - flow water. As cable protection sleeves inside wind turbine towers, it provides mechanical protection
4. Industrial Field: Transports corrosive media in chemical enterprises, ensuring safety with anti-corrosion coatings. Used as power pipelines in factories to achieve stable and efficient transmission.
5. Transportation: Used as bridge pile foundations and support structures, bearing loads with high strength. Applied as ventilation and drainage pipelines in tunnels to meet the requirements of special environments.
