The ASTM A192 specification outlines seamless carbon steel boiler tubes designed for high-pressure applications. When you send us an inquiry, we will recommend suitable pipe sizes based on your requirements. To ensure accuracy, please include a printout or sketch of the part to be manufactured. We take into account factors such as grade, chemical composition, and surface condition, and tailor the production process to meet the specific needs of the end use. ASTM A192 seamless steel pipes are commonly used as minimum wall thickness tubes in high-pressure boilers, superheaters, and other critical components. CSCsteel offers ASTM A192 pipes in both hot-rolled and cold-drawn conditions. These pipes are typically used in high-pressure steam boilers operating at pressures not exceeding 9.8 MPa and temperatures ranging from 450°C to 650°C. They are ideal for heating surfaces, headers, economizers, superheaters, and reheaters. We also provide additional processing services such as pipe end preparations (flat, beveled, or threaded ends), coatings (epoxy, paint, or 3LPE), and bending, all customized to meet customer specifications.
