The pressure rating of steel pipes:

The pressure rating of steel pipes is usually expressed in "Mpa", i.e. megapascals. The standard pressure rating of ordinary steel pipes is usually 3Mpa, 6Mpa, 10Mpa, 16Mpa, 20Mpa, etc., which represent different pressure-bearing capacities of the pipes. Generally, the manufacturer of the steel pipes will mark the pressure rating and pressure range on the pipes for reference by users.

Compared with ordinary steel pipes, seamless steel pipes have better pressure-bearing capacity, and their pressure rating will also be different. Generally speaking, the standard pressure rating of seamless steel pipes is 10Mpa, 20Mpa, 35Mpa, 45Mpa, etc. Similarly, the manufacturer of seamless steel pipes will also mark the pressure rating and pressure range on the pipes.

Pressure rating of HDPE pipes:

According to the product standards of HDPE pipes at home and abroad, the pressure range of HDPE pipes is generally within 2.0 Mpa at present.

Therefore, in terms of working pressure only, HDPE pipes do not perform as well as steel pipes. This is only an analysis in terms of working pressure. In terms of corrosion resistance, flexibility, and service life, the advantages of HDPE pipes are obvious.HDPE
