With Plastic
Technical requirements for composite material pipes:
1. Colors are typically black, blue, or white; high-temperature-resistant pipes are usually orange, or can be agreed upon by both parties based on supply and demand.
2. The inner and outer surfaces of the tubing should be smooth and even, allowing for minor concave and convex indentations due to natural shrinkage. Bubbles, cracks, decomposition变色 lines, and obvious scratches are not permitted. The ends of the tubing should be cut cleanly and flat.
3. The pipe end caps have a good fusion with the pipe material, with no cracks, smooth joints, and no scratches or burrs.
