Brief: From concept to demonstration, this video highlights the evolution and practical outcomes of 4130 30CrMo and 4140 42CrMo Alloy CrMo Steel Tubes. You will see the manufacturing process, from raw material inspection and cold drawing to heat treatment and final quality testing, showcasing how these tubes meet international standards for demanding applications.
Related Product Features:
  • Manufactured to ASTM A519, DIN1629, and EN10305-1 standards for seamless alloy steel tubes.
  • Available in a wide range of outside diameters from 1/2 inch to 24 inches (21.3mm to 609.6mm).
  • Offers various thickness schedules including SCH5S, SCH10S, SCH20, SCH40, SCH80, SCH160, and XS.
  • Produced using hot piercing for sizes 1/2' to 6' and hot extrusion for sizes 6' to 24'.
  • Multiple surface treatments available: black painted, galvanized, natural, anticorrosive 3PE coated, and polyurethane foam insulation.
  • End options include bevel end for diameters over 2 inches, plain end for diameters 2 inches and under, with plastic caps or screwed and socket ends.
  • Suitable for diverse applications such as oil pipelines, drill pipes, hydraulic pipes, gas pipes, boiler pipes, and shipbuilding.
  • Comprehensive quality control includes tensile strength, yield strength, elongation, hardness, and straightness testing.
Faqs:
  • What are the key international standards that these CrMo steel tubes comply with?
    These alloy CrMo steel tubes comply with standards including ASTM A519, DIN1629, EN10305-1, API 5L, ASTM A106, ASTM A53, and others, ensuring they meet rigorous quality and performance requirements for global applications.
  • What quality control measures are implemented during the manufacturing process?
    The manufacturing process includes incoming raw material inspection, segregation to prevent grade mix-up, heating and hammering for cold drawing, on-line inspection during cold drawing/rolling, heat treatment (SR, A, N), straightening/cutting, and final quality testing for tensile strength, yield strength, elongation, hardness, and straightness in our own lab.
  • What are the common applications for 4130 30CrMo and 4140 42CrMo alloy steel tubes?
    These tubes are widely used in oil pipelines, drill pipes, hydraulic systems, gas pipelines, fluid transport, boiler pipes, conduit pipes, scaffolding, and in industries such as pharmaceuticals and shipbuilding due to their strength and durability.
