Seamless steel tubes used in the engineering structure of Ansteel
Seamless steel tubes are widely used in engineering structures. The seamless steel tubes used in Ansteel engineering structures are mainly of two international standards, namely German DIN and US ASTM. The seamless steel tube material of these two standards is also different, and the application range is also different. This article mainly introduces the seamless steel tube material applied in the engineering structure of Ansteel.
DIN Seamless Steel Pipe
The DIN seamless steel tubes used in Ansteel engineering structures mainly include DIN2391 ST35 cold-drawn precision seamless steel pipe, DIN2391 ST37 cold-drawn precision seamless steel pipe, DIN1629 ST37 seamless steel pipe, DIN1629 ST45 seamless steel pipe and DIN17175 seamless steel pipe. The material of these seamless steel pipes is mainly 10# 20# 45# 16Mn 27SiMn 35CrMo. The regular billet is 12 meters and 15 meters long, the thickness is 0.8mm-14mm and the outer diameter is 4mm-80mm.
ASTM Seamless Steel Pipe
The ASTM seamless steel tubes used in the engineering structure of Ansteel mainly include ASTM A106/A53 GrB seamless steel pipe and ASTM A192 seamless steel pipe. The material is mainly 10# 20# A 106 GrB A53 GrB A192. The length varies from 4 meters to 12 meters. The outer diameter is 1/8”-14” and the thickness is 0.02”-1”.
Application of Seamless Steel Tubes in Engineering Structure
Seamless steel tubes are mainly used in oil pipelines and chemical pipelines of engineering structures. DIN seamless steel tubes are mainly used in general oil pipelines, structural engineering and other fields. ASTM seamless steel pipes are mainly used in chemical pipelines, ordinary pipelines and mechanical structures. The seamless steel tubes used in Ansteel engineering structures must meet the design specifications and must be periodically inspected and tested to guarantee the reliability of the engineering structure.
Conclusion
Seamless steel tubes have been widely used in the engineering structures. The seamless steel tubes used in Ansteel engineering structures include two international standards of DIN and ASTM. The main material is 10# 20# 45# 16Mn 27SiMn 35CrMo and so on. The length is usually between 4 meters and 12 meters. The external diameter is 4mm-80mm, and thickness is 0.02”-1”. The main application of seamless steel tubes in engineering structures are mainly oil pipelines and chemical pipelines. Seamless steel tubes must meet the design specifications and must be periodically inspected and tested to guarantee the reliability of the engineering structure.
