Selecting the right material for heat exchanger pipes involves balancing multiple factors, including corrosion resistance, thermal conductivity, mechanical strength, cost, and compatibility with the fluids. By carefully considering these criteria, engineers can choose materials that optimize the performance and longevity of the heat exchanger, while also meeting budgetary and regulatory requirements.
Material selection represents a key design factor governing long-term heat exchanger reliability and costs. While carbon steel dominates many lower temperature applications, excellent corrosion resistance and high temperature strength motivate using stainless steels, nickel alloys or linings/coatings especially for demanding service conditions. Performance must be balanced judiciously against constraints like budgets or weight to procure piping optimized for a heat exchanger's full service life.
ASTM A179 covers minimum-wall thickness, seamless cold-drawn steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. It is a kind of low-carbon tubes shall be made by the seamless process and shall be cold drawn.
DIN 17175 is designed for elevated temperature purposes, ABTER STEEL supplies following steel grades: St35.8, St45.8, 15Mo3, 13CrMo44, 10CrMo910. DIN 17175 seamless steel pipes are widely used in heat exchange appliances.
ASTM A179 covers minimum-wall thickness, seamless cold-drawn steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. It is a kind of low-carbon tubes shall be made by the seamless process and shall be cold drawn.
EN10216-2 is specification made for seamless steel tubes for specified elevated temperature purposes as boiler tube, power plants, etc, it has following steel grades: P195GH, P235GH, P265GH, 16Mo3, 14MoV6-3, 13CrMo4-5, 10CrMo9-10, with non-alloy and alloy steel included.
The EN 10217-1 standard is the European standard for welded pressure pipes, it governs the technical requirements for carbon steel tubes. This standard is suitable for welding carbon steel tubes which having specified room temperature properties and rated pressures. The essential requirements of this standard are minimum yield point strength and tensile strength, elongation, weldability, Impact values, non-destructive test, etc. This standard is widely used in the construction of pressure vessels and piping systems in the oil and gas, petrochemical, and Power industries.
A heat exchanger is a device that transfers heat from one medium to another, often with the goal of reusing or recycling heat that would otherwise be wasted or lost. The process of heat exchange is fundamental to many everyday appliances, such as refrigerators and air conditioners, and is also critical in many industrial applications.
ASTM A179,ASME SA179 steel tubes covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.
