The production of stainless steel coiled tubing involves several critical steps to ensure quality and performance:
- Pilgering: This cold-working process reduces the diameter and wall thickness of the tubing to precise dimensions.
- Precision Drawing: Tubing is drawn through dies to achieve tight tolerances and smooth surface finishes.
- Orbital Welding: For welded tubing, orbital welding ensures consistent, high-quality welds with minimal defects.
- Annealing: Heat treatment processes such as bright annealing restore ductility and corrosion resistance after cold working.
- Coiling: Tubing is carefully coiled onto reels for easy transportation and installation.
- Seamless Construction: Seamless tubing eliminates weld seams, reducing the risk of leaks and improving strength under pressure.
- Long Continuous Lengths: Coiled tubing can be supplied in lengths up to several kilometers, reducing the need for joints and fittings.
- Corrosion Resistance: Stainless steel alloys resist oxidation and chemical attack, extending the service life of tubing in harsh environments.
- Flexibility and Ease of Installation: Coiled tubing's flexibility allows for easier routing in complex installations, saving time and labor costs.
- Customization: Manufacturers can tailor tubing dimensions, materials, and finishes to meet specific application requirements.
