What is the role of PPR pipe and its cleaning and maintenance?

1. Introduction and function of PPR tube
PPR pipe is also called random copolymer polypropylene (PPR). The product has good toughness, high strength, excellent processing performance, good creep resistance at higher temperatures, and has the unique advantages of high transparency of random copolymer polypropylene. It can be widely used in the production of pipes, sheets, daily necessities, packaging materials, household appliances and various films.

Compared with traditional cast iron pipes, galvanized steel pipes, and cement pipes, it has the advantages of energy saving, material saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall without scaling, simple construction and maintenance, and long service life. It is widely used Building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheath, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields.

2. Cleaning and maintenance of PPR pipe
1. The PPR pipe should be concealed under pressure. Generally, the working pressure should be used as the holding pressure, and the pressure can be reduced after the hidden layer reaches the allowable strength.
2. Due to the soft texture of PPR pipes, the mechanical strength is not as high as steel pipes, so physical damage should be strictly prevented. It is strictly forbidden to knock, touch, smash or press the pipeline after installation. Covering and protection measures should be taken before concealment. Before the pipeline in the pipeline well is closed, certain measures should be taken to prevent bricks and debris from falling and breaking the pipeline; due to the constituent elements of PP-R pipe, it has strong resistance to chemical damage, and chemical damage is in construction Easily overlooked. For installation outdoors or with
3. During the low temperature period in winter, if there is no good insulation measures, the water in the PPR pipe should be blown off in time to prevent the pipe from freezing.
4. After the concealment is completed, a mark must be made to prevent other construction from damaging the pipeline.
