The above is the standard of the pipes produced by Pandapipe in different situations, once again, Pandapipe has several production lines including ERW/SMLS/SSAW/LSAW and pipe coating lines and Pandapipe has several certificates and accreditations to produce pipes in strict compliance with the international standards, Pandapipe also has its own laboratory to analyse/experiment/test the composition of pipes to be more accurate and to prolong the efficiency of the use of the pipes. Pandapipe also has its own laboratory for analysing/experimenting/checking the composition of the pipes, which allows for a more accurate and efficient use of the pipes.
Below is a list of all the pipes produced by Pandapipe, and a comparison table of pipe standards, each pipe table is in pdf format, you can download it for your own reference.

ERW (Electric Resistance Welded) Welded Steel Pipe
ERW is made by resistance welding, where a steel plate is rolled into a tube and the joints are welded using high frequency electric welding technology. As a result there is a welded seam in the tube itself. This method is suitable for steel pipes with relatively small diameters.The advantages of ERW pipes are relatively low cost, high production efficiency and adaptability to many environments. Moreover, resistance welding technology is now so mature that the material at the weld seam is comparable to the steel plate itself.
SMLS (Seamless) Seamless Steel Pipe
SMLS or Seamless Steel Tubes are made directly from high temperature extruded and drawn billets, with no welding step in the tube itself. They can be transported under very specific high pressure conditions. The main disadvantages are the high cost, non-smooth wall surface and non-uniform wall thickness. Therefore, this process is only considered for special applications.
SSAW (Spiral Submerged Arc Welded) Steel Tubing
SSAW steel pipe is made by bending hot rolled steel strip into a tube in a spiral shape and welded using double-sided submerged arc welding technology. This process is mainly used for the production of large-diameter steel pipe or thick-walled steel pipe. The main disadvantage is that there will be more welds.
LSAW (Longitudinally Submerged Arc Welded) Steel Pipe
Longitudinally Submerged Arc Welded (LSAW) tubes are made by submerging one or both sides of a longitudinally orientated strip and are often used for the transport of oil/gas under high pressure. In contrast to other processes, LSAW has only one straight weld seam and the overall strength and quality of the pipe is very controlled.
