LaserLine™ Coiled Tubing Specifications

ASTM B704

Standard Specification for Welded UNS N06626 & N08825 Alloy Tubes

This specification covers welded nickel alloy tubing for boiler, heat exchanger, condenser, and general corrosion resisting and low or high temperature service applications. The grades covered by this specification are Alloy 625 (UNS N06625) and Alloy 825 (UNS N08825). Webco manufactures tubing for the above applications and for various oil & gas applications in coiled tubing configurations. These grades belong to the nickel-chromium-molybdenum family of corrosion resistant alloys that are especially resistant to oxidizing and reducing acid environments.

ASTM A789 / ASME SA789

Standard Specification for Seamless & Welded Ferritic/Austenitic Stainless Steel Tubing for General Service

This specification covers tubing designed for general corrosion resistance with emphasis on resistance to stress corrosion cracking. Grades designated here are susceptible to embrittlement if used for prolonged periods at elevated temperatures. Duplex grades, a combination of austenitic and ferritic chemistries in one, are certified to this specification and must be provided in the annealed condition. Duplex grades (such as 2205) were designed to afford the good corrosion resistance characteristics of austenitics with the strength of ferritics. Webco manufactures tubing to this specification on a customer/application specific basis.

ASTM A269

Standard Specification for Seamless & Welded Austenitic Stainless Steel Tubing for General Service

This tubing specification details the manufacturing criteria for average-walled, Type 300 series (nonmagnetic) stainless grades (304L, 316L, etc.). These grades are typically used in general corrosion resisting and low to high temperature service environments. Types 304L and 316L are the most common grades used, however other grades are covered by this specification. This specification does require the tubing to be in the annealed condition. These grades are generally work-hardenable. Webco offers its tubing in the bright annealed condition and stocks many sizes for immediate shipment.

ASTM A249 / ASME SA249

Standard Specification for Welded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes

This specification covers a wide range of austenitic grades used in these applications. All tubing must be supplied in the annealed condition and include cold working of the weld area prior to final heat treatment. At the option of the purchaser, tubes must be additionally certified to pass the Weld Decay Test, as called out in Section S7. This corrosion test requires that the base metal corrode at a faster rate than the weld area. Webco manufactures tubing to this specification and can additionally certify to the Weld Decay Test, if requested.

ASTM A632

Standard Specification for Small Diameter Seamless & Welded Austenitic Stainless Steel tubing for General Service

This specification requires tighter tolerance manufacturing, heat treated tubing, and imposes additional testing criteria, including minimal tensile requirements, more rigorous manipulation test frequency, intergranular corrosion certification, and cleanliness testing, than its counterpart specification, A269. It covers Type 300 grades of stainless in outside diameters of " and down. Webco manufactures tubing to this specification on a customer/application specific basis.
