There are two section types of the pre-galvanized hollow pipes,the square hollow pipe and rectangular pipe. The size of the hollow pipe can reach 12x12-500mm, and the thickness of the pipe can reach 0.6-20mm. The material grade can reach Q195-Q235. The hollow pipes are bundle with steel strips. And

Pipe selection and wall thickness

Calculating the Size/Weight of Structural Steel and Miscellaneous Metals

Pipe selection and wall thicknessSteel pipe is required in the majority of oil and gas production and pipeline applications. ASME A53 and A106 and API 5L seamless, electric resistance welding (ERW), and submerged arc welding (SAW) steel pipe are commercially available and most commonly used in pipe

Steel PipeA curved steel pipe supplied with a discharge-regulating device to direct the jet onto the buckets in impulse runners.

All in-service pipelines encounter deterioration due to environmental effects. The deterioration is a time-dependent process which makes the structural integrity of pipelines a time variant characteristic. Advanced mathematical methods which employ probability theory need to be used for time-depende
