Pipe & Tube

Metalsin Tech supplies a variety of electric-fusion-welded (EFW) austenitic chromium-nickel alloy steel (stainless steel) pipes made in accordance with ASTM A358. The EFW process produces a uniform and consistent weld and pipe wall, crucial for maintaining the pipe’s integrity under high-temperature, high-pressure, and corrosive conditions. These pipes are intended for severe service such as petrochemical, chemical, oil and gas, pharmaceutical, …

Duplex stainless steel tubing and pipes, either seamless or welded, are intended for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. There are several prevalent duplex grades that can be readily sourced from most pipe mills: UNS S31803, UNS S32205, UNS S32750 and UNS S32760. Both S31803 and S32205 are designated as alloy 2205, …

Sizes & Dimensions The ASTM A269 tubing refers to series of seamless or welded austenitic stainless steel tubing for general corrosion-resisting and low- or high-temperature service. The tubing or tube is generally furnished with round cross section in either straight-cut length or coil. Among all austenitic stainless steels, TP304, TP304L, TP316 and TP316L are the most widely used grades and …

Scope SAE J3129 is the standard released by Society of Automotive Engineers to standardize stainless steel bulk tubing. Seamless 304/304L stainless steel tubing manufactured in accordance with this standard is intended for use as hydraulic lines and in other applications requiring corrosion resistance. Material & Manufacture The seamless tubing shall be made from stainless steel conforming to the chemical composition …

Material Grades & Specifications Seamless tubes made of ASTM A213 Grade TP316 or Grade TP316L are generally used for the construction of boilers, superheaters or heat exchangers. They are also know as TP316/ TP316L boiler tubes, superheater tubes, or heat exchanger tubes. The UNS designations of ASTM A213 TP316 and TP316L are S31600 and S31603, respectively, with the P number …

Sizes & Wall Thicknesses Stainless steel 304/ 304L seamless boiler tubes, superheater tubes, and heat-exchanger tubes shall be made of ASTM A213 Grade TP304/ TP304L steels. The tubing sizes and thicknesses usually furnished to this specification are 1/8″ in inside diameter to 5″ in outside diameter and 0.015″ to 0.500″, inclusive, in minimum wall thickness or, if specified in the …

General Introduction & Applications ASTM A312 Grade TP316 and TP316L refer to the stainless steel 316 and 316L respectively. The prefix “TP” denotes “type” of the stainless steel. TP316 or TP316L pipes may be furnished in seamless or longitudinally welded types with butt welding ends or threaded ends. TP316 is derived from the classic “18-8” (TP304) stainless steel by adding …

Pipes of stainless steel 304 or its low-carbon version 304L may be made in accordance with ASTM A312 Grade TP304 or TP304L, respectively. The TP304 and TP304L pipes may be furnished in seamless or straight-beam (longitudinally) welded types. They are primarily intended for high-temperature and general corrosion service. TP304/ TP304L seamless pipes shall be made by a cold-drawn or hot-rolled …

Standard, Size & Wall Thickness ASTM A192, identical with ASME SA-192, is the standard specification covering minimum-wall-thickness seamless carbon steel boiler and superheater tubes for high pressure service. The tubing sizes and thicknesses usually furnished to ASTM A192 are 1/2″ to 7″ [12.7 mm to 177.8 mm] outside diameter and 0.085″ to 1.000″ [2.2 mm to 25.4 mm], inclusive, in …

Standard, Size, Manufacture & Heat Treatment ASTM A179, identical with ASME SA-179, is the standard specification covering minimum-wall-thickness cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. This specification cover tubes 1/8″ to 3″ [3.2 mm to 76.2 mm], inclusive, in outside diameter. The ASTM A179 tubes shall be made by the seamless process and …

General Introduction ASTM A178, identical with ASME SA-178, is the standard specification covering minimum-wall-thickness, electric-resistance-welded tubes made of carbon steel and carbon-manganese steel intended for use as boiler tubes, boiler flues, superheater flues, and safe ends. There are three grades available: Grade A – low-carbon steel, Grade C – medium-carbon steel, Grade D – carbon-manganese steel. Sizes & Thicknesses The …

ASTM A135, identical with ASME SA-135, is the standard specification for electric-resistance-welded steel pipe. It covers two grades of ERW steel pipe in NPS 2 to NPS 30 [DN 50 to DN 750], with nominal (average) wall thickness up to 0.500″ [12.7 mm], and in nominal sizes NPS 3/4 to NPS 5 [DN 20 to DN 125] with nominal (average) …
