DIN 17175 Steel Pipe for boilers | heat exchanger tubes | high temperatures and pressures
what is the DIN 17175 Steel Pipe?
DIN 17175 steel pipe is a German standard that specifies seamless tubes made of heat-resistant steels, designed primarily for high-pressure applications. These steel pipes are manufactured from carbon and alloy steel grades, which can endure high pressure and temperature conditions. The main purpose of DIN 17175 steel pipes is to be used in boiler installations, high-pressure pipelines, and tank construction where high temperatures and pressures are involved.
Some key characteristics and uses of DIN 17175 steel pipes are:
- High heat and pressure resistance: DIN 17175 steel pipes are designed to withstand high temperatures and pressures, making them suitable for demanding applications.
- Good mechanical properties at elevated temperatures: The steel grades used in DIN 17175 pipes exhibit excellent mechanical properties when exposed to high temperatures, ensuring the pipes’ durability and reliability.
- Wide range of applications: DIN 17175 steel pipes are commonly used in various high-temperature applications, such as power generation, petrochemical, and chemical industries.The pipes under DIN 17175 are manufactured from carbon and low-alloy steel grades which are resistant to loads under high pressure and temperatures. They are used for the construction of power engineering appliances such as: boilers, heating coils, stoves, heaters, heat exchanger tubes.
The main steel grades used in DIN 17175 steel pipes are:
-
- St35.8
- St45.8
- 17Mn4
- 19Mn5
- 15Mo3
- 13CrMo44
- 10CrMo910
- 14MoV63
- X20CrMoV121
These steel grades have different chemical compositions and mechanical properties, making them suitable for different applications and operating conditions. The appropriate steel grade should be chosen based on the specific requirements of your project.
DIN 17175 steel pipes are available in various sizes and thicknesses and can be supplied with plain ends, beveled ends, or threaded ends, depending on the customer’s requirements. To ensure high quality, these pipes are usually subject to non-destructive testing, such as ultrasonic testing, eddy current testing, and radiographic testing.
When using DIN 17175 steel pipes in your project, it’s essential to consult with an engineer or a professional who can guide you on the right material selection and installation practices. Additionally, make sure to adhere to the relevant safety standards and regulations when working with high-pressure equipment.

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.
According to ASTM specifications, this particular specification pertains to seamless ferritic and austenitic steel tubes for use in boilers, superheaters, and heat exchangers. The specific grades covered by this specification include T5, TP304, and others listed in Tables 1 and 2. The tubing size ranges from an internal diameter of 1/8 inch up to an outer diameter of 5 inches, with thicknesses ranging from 0.015 to 0.500 inches (0.4 mm to 12.7 mm). If other sizes are required, they can be specified as part of the order, along with minimum and average thicknesses.
