PRODUCT OVERVIEW

Our company specializes in manufacturing welded stainless steel coil tubing, utilizing advanced high-frequency welding (TIG) and laser welding (LBW) technologies, coupled with a rigorous quality control system. We provide high-precision, corrosion-resistant, and heat-resistant piping solutions for industries such as chemical, medical, food processing, heat exchangers, instrumentation, and semiconductors. Our products comply with international standards such as ASTM A269 and ASTM A249, offering excellent mechanical properties and cost-effectiveness.

Product Core Parameters.

- Wall Thickness Range: 0.3mm - 2.0mm

- Material Options: 304, 304L, 321, 316, 316L austenitic stainless steel (Other special materials available upon request)

- Production Standards: ASTM A269 (General seamless and welded tubes), ASTM A249 (Welded tubes for boilers and heat exchangers)

- Surface Treatment: Bright annealed (BA).

- Coil Length: Continuous coil or cut-to-length, adaptable to customer installation needs.

Product Advantages.

Precision Welding Technology: Utilizes automated welding and online eddy current testing (EDDY) to ensure uniform welds, no leaks, and internal surface smoothness of Ra ≤ 0.8μm, meeting high-purity fluid transmission requirements.

Outstanding Material Performance:

  - 304/304L: General-purpose stainless steel with corrosion resistance to acids and alkalis, suitable for food-grade environments.

  - 321: Contains titanium for excellent resistance to intergranular corrosion, ideal for high-temperature applications (e.g., heat exchangers).

  - 316L: Enhanced resistance to chloride ion corrosion due to molybdenum, suitable for seawater, chemical, and harsh environments.

Strict Quality Control:

100% non-destructive testing (NDT) of welds (hydrostatic/pneumatic testing, X-ray inspection available).

 Meets ASTM standard chemical composition and mechanical properties, with material certificates and third-party certifications provided.

High Cost-Effectiveness and Flexibility:

Compared to seamless tubes, welded coils offer lower costs at equivalent performance levels and support small-batch customized production (e.g., special cross-sections, wall thicknesses).

Typical Application Areas.

- Heat Exchange Systems: Air conditioning and refrigeration coils, condensers, evaporator pipes.

- Industrial Fluid Transfer: Chemical medium conveyance, hydraulic oil lines, high-purity gas lines for semiconductors.

- Medical Equipment: Medical gas lines, aseptic pipelines for pharmaceutical equipment.

- Food and Beverage: Pipelines for dairy processing, brewing equipment.

- New Energy and Environment: Hydrogen storage and transportation tubes, wastewater treatment systems.

Service Commitments.

- Quick Response: Ample inventory of standard specifications, supporting urgent order expediting.

- Technical Support: Provides selection guidance, welding process recommendations, and installation optimization.

- Global Delivery: Offers standardized packaging (moisture-proof, impact-resistant) and international logistics services.
