1. Dramatic Reduction in Installation Costs & Leak Risks
ASEA METAL's SMLS Coil Tubing reaches up to 2,000 meters. By eliminating 50-80% of welds, we reduce leak points in Subsea Umbilicals and Control Lines.

2. Superior Surface Quality via Bright Annealing (BA)
Specialized BA process results in a mirror-like finish, minimizing friction and maximizing corrosion resistance for Aerospace and Chromatography.

3. Strict Compliance with Global Standards (ASTM & EN)
Full compliance with ASTM A213, A269, and EN 10216-5. 100% Eddy Current and hydrostatic tested with full MTR traceability.

4. Versatile Material Range (Duplex & High-Nickel)
Beyond TP316L, we offer Duplex S31803, Super Duplex S32750, Monel 400, and Inconel 625 with Chemical Compatibility Analysis.

1. Seamless Integrity and Ultra-Long Length Advantage ASEA METAL’s SMLS (Seamless) Coil Tubing is manufactured using a precision cold-drawing process, ensuring a completely seamless structure with no weld seams. This eliminates the risk of Weld Heat Affected Zone (HAZ) corrosion, a common failure point in welded alternatives. Our capability to produce continuous lengths up to 2,000 meters per coil significantly reduces the need for orbital welds and mechanical fittings by 50-80%. This "Seamless Integrity" is critical for high-stakes applications such as Subsea Umbilicals, Chemical Injection Lines, and Downhole Control Lines, where leak prevention is paramount and repair costs are astronomical.

2. High-Purity Surface via Bright Annealing (BA) Process To meet the stringent requirements of high-tech industries, all our coil tubes undergo a specialized Bright Annealing (BA) process in a controlled hydrogen atmosphere. This heat treatment prevents oxidation and results in a mirror-like internal and external surface finish. A superior surface roughness (Ra) minimizes friction for fluid flow, prevents micro-particle entrapment, and maximizes resistance to pitting corrosion. It is the gold standard for Analytical Chromatography, Aerospace fuel lines, and High-purity Semiconductor Gas systems.

3. Strict Compliance with International Standards and Quality Assurance We guarantee 100% compliance with global standards, including ASTM A213, A269, A632, and EN 10216-5 TC1/TC2. Every millimeter of our coil is subjected to Non-Destructive Testing (NDT), including 100% Eddy Current Testing (ECT). Upon request, we perform rigorous Hydrostatic or Pneumatic testing at pressures exceeding 1.5 times the design limit. Full Material Test Reports (MTR) provide 100% traceability for chemical composition, mechanical properties (Tensile, Yield, Elongation), and hardness, ensuring adherence to ASME Section III and PED (Pressure Equipment Directive) safety codes.

4. Specialized Alloys for Extreme Corrosive Environments Beyond standard TP316/316L, ASEA METAL specializes in high-performance alloys engineered for extreme offshore and refinery environments:
• Duplex & Super Duplex (S31803 / S32750): Exceptional resistance to Chloride Stress Corrosion Cracking (SCC).
• Nickel Alloys (Monel 400, Inconel 625, Alloy 825): Superior performance in Sour Service (H2S) and high-temperature petrochemical processing.

5. Precision Tolerances and Optimized Logistics Packaging We maintain ultra-tight tolerances on Outside Diameter (O.D.) and Wall Thickness (W.T.) to ensure perfect compatibility with instrumentation compression fittings. To ensure the tubing arrives in factory-perfect condition, we utilize specialized Steel or Wooden Reels with UV-resistant wrapping, preventing kinking or surface abrasions during global transit.
