longitudinal steel pipe steels

Steel pipe longitudinal cracksSteel pipe longitudinal cracks. Longitudinal cracks are formed as a result of excessive soil and traffic loads or inadequate pipe bedding. Visible longitudinal cracks observed at top and invert inside the pipe should be more severe than those on the outside because tensile stress occur at top and invert portion of the inside of the pipes.

Difference between helical welded pipes and longitudinal longitudinal steel pipe steels

As for longitudinal welding, the width of the steel plate should be strictly stuck to the diameter of the pipe. Once the steel is cut for rolling, it cannot be changed, which means the diameter of the longitudinal pipe is fixed. While for helical welding, it can achieve various diameters of pipes by rolling the steel plate with different angles longitudinal steel pipe steelsDifference between helical welded pipes and longitudinal longitudinal steel pipe steelsAs for longitudinal welding, the width of the steel plate should be strictly stuck to the diameter of the pipe.

Solutions of normalised fully plastic J-integral (h) for steel pipes are developed. The distribution of h changes with different crack aspect ratios and depths. There is a significant difference in h between the thick-wall and thin-wall pipes. The strain hardening exponent has the largest influence on h.
