Plastic Coated Steel Tube

A plastic coated steel tube is made from a carbon steel tube and a plastic protective layer. The coating works as a barrier between the steel and moisture, soil, or water in the pipe. This type is common in fire sprinkler lines, protective casing, and pipe runs that need steel strength but also need better surface protection than plain black pipe.

In fire protection work, the red plastic coated steel tube is easy to identify on site and can be fitted into sprinkler or hydrant pipe systems. The inner coating gives a smoother water path and helps slow down rust inside the line. The outer coating also helps when the pipe passes through humid rooms or shallow buried sections. This product should be checked at the cut end before assembly, because exposed steel at the edge may need repair coating. With suitable fittings and pressure testing, this product can be used as a practical pipe for fire water, building service water, and simple protection work.

1. Steel tube body formed to the required diameter and wall thickness.

2. Bonded plastic coating on the selected surface.

3. Pipe end treatment for groove, flange, or thread connection.

1. For plastic coated steel tube, the coating lowers direct contact between water and steel.

2. The steel tube keeps a firm shape during transport and installation.

3. Colored coating helps workers separate fire lines, water lines, and utility lines.

1. Check coating scratches before the pipe enters the trench or pipe rack.
2. Keep pipe ends clean before adding seal rings or flanges.
3. Avoid dragging the tube on stone, steel scrap, or rough ground.
