What is the difference between ASTM A179 pipe and DIN 17175 pipe ?

ASTM A179 Low Temperature Carbon Steel Tube

ASTM A179 (ASME SA179) Pipe Description

Cold drawn seamless carbon steel tube for heat exchangers and condensers
Size (mm): O.D.:6.0~114.0; W.T.:1~15; L: max 12000

Description:
1. Standards: ASTM A179 (ASME SA179)
2. Applications: heat exchangers, condensers, heat transfer equipment and similar pipes.
3. Grade: A 179
4. Specifications: diameter 10.3 to 76.2 mm; thickness: 1.2 to 12 mm; length: 6 m and above; and, modified specifications according to customer requirements.
5. Chemical composition and mechanical properties.

DIN 17175 Alloy pipe Description

Standard: DIN 17175
We can supply various grades of seamless boiler pipes, such as St35.8, St45.8, 15Mo3, 13CrMo44, 10CrMo910, etc.

Size RangeThe size range of JST seamless steel boiler tube is as follows:

Outer dimension is from 6.0 mm to 219.0 mm.
Wall thickness of DIN 17175 seamless boiler pipe ranges from 1 mm to 30 mm.
The maximum length is 12 m.

DIN 17175 seamless steel tube for elevated temperature St35.8, St45.8, 17Mn4, 19Mn5, 15Mo3, 13CrMo44

This seamless boiler pipe can also be used as heating surface pipe, economizer, superheater, reheater and petrochemical industrial pipe for high-pressure boilers (The working pressure is above hunting for.8 Mpa in general and the working temperature is between 450℃ to 650℃. ).
