GB/T 14291 Q235 Welded Steel Tubes For Mine Liquid Service Product Overview GB/T 14291 Q235 welded steel tubes are straight-seam ERW carbon steel tubes specifically designed for mine liquid and auxiliary fluid service applications. These tubes are engineered for use in mine pressured-air lines, drainage systems, gas-drainage lines, and slurry transportation. Manufactured primarily from Q235A/Q235B mild steel, with optional higher-strength grades including Q295 and Q345 for

Precision Cold Drawn Cold Sized Tubes Welded Steel Tubes EN10305-3 For Automobile Introduction Precision cold drawn cold sized tubes, also known as welded steel tubes EN10305-3, are widely used in the automobile industry. These tubes are manufactured with utmost precision to meet the demanding requirements of automotive applications. In this article, we will explore the material, specification, chemical composition, mechanical properties, steel grade, and application of these

SAE J525 ERW / DOM Welded Steel Tube Low Carbon Annealed For Automotive Industry SAE J525 ERW/DOM Welded Low-Carbon Annealed Steel Tube for Automotive Hydraulic Lines SAE J525 ERW/DOM welded steel tube is a normalized, cold-drawn, single-wall low-carbon steel pressure tube designed for automotive fluid-line parts requiring bending, flaring, forming, and brazing. It is a practical choice when the drawing requires tight OD/ID control, good concentricity, a smooth surface, and

ASTM A214 is a specification that covers minimum-wall-thickness, electric-resistance-welded, carbon steel tubes to be used for heat exchangers, condensers, and similar heat-transfer apparatus. These tubes are commonly used in boilers, superheaters, and air coolers. Material and Specification The material used in ASTM A214 is carbon steel, and the tubes are electric-resistance-welded. The specification covers a range of sizes and thicknesses, as shown in the table below.

SA178 Grade A / Grade C / Grade D Electric-Resistance-Welded Carbon & Carbon-Manganese Steel Tube for Heat Exchangers Material SA178 (equivalent to ASTM A178) is a minimum-wall-thickness electric-resistance-welded (ERW) tubing product made from carbon steel (Grade A, Grade C) and carbon-manganese steel (Grade D) . It is widely specified for boiler tubes, boiler flues, superheater flues, and safe ends , and is also commonly selected for heat-transfer service where stable weld

SGP Welded Carbon Steel Pipe (ERW Steel Tube) for Ordinary Piping Material This product is an electric-resistance-welded (ERW) carbon steel pipe designed for ordinary/utility piping —typically used to convey steam, water, oil, gas, air, and other general fluids under relatively low service pressure . Specifications Manufacturing process: High-frequency ERW longitudinal seam. Typical size range (SGP / JIS ordinary piping): OD 10.5–508.0 mm (DN 6A–500A) with corresponding

S235JR Square Tube Carbon Steel Square Tube for Industrial Use Material S235JR is a non-alloy structural (mild) carbon steel grade used for general-purpose load-bearing fabrication. In cold-formed square hollow sections (SHS) , steel strip/plate is roll-formed at ambient temperature, welded (typically high-frequency), and then sized to achieve stable geometry and consistent dimensions.Note on designation: for European hollow sections, the grade is often specified as S235JRH
