DIN 1629 St37 St52 St44 hot rolled and cold drawn seamless
mechnical tubing , hot finished carbon steel pipes
DIN 1629 Seamless Steel pipe Of Non Alloys Steels are made of unalloyed steels, it's main grades are St 37.0, St44.0,
St52.0, Din 1629 seamless steel pipes application fields are: chemical plant, vessels, pipework
construction and for common mechanical engineering purposes.
Normally DIN 1629 standard are manufactured with no limiting
working pressure values. Working temperature is limited below 300℃.
2. Size Range: OD: 6-229mm, WT: 1-15mm, Length: 5.8m/6m, maximal
11.8m
3. Stable Quality with Comeptitive Price
4. High Performance and Longer Working Life Steel Pipe
Application: DIN1629 Steel Tubes are used in the construction of
chemical plant, vessels, pipework and for general mechanical
engineering purpose.
100% Eddy Current Testing.
100% Size Tolerance Checking.
100% Tube surface checking to avoid surface defects.

upper transformation point under shielding gas or in a vacuum),
minimum values of yield stress lower than these valued by 20N/mm²
are permitted. ²) For cold finished tubes in the NBK condition, minimum values of tensile strength lower than these values by 10N/mm² are permitted. | |||||||
