Fire pipes can be installed in owner hygiene? And is the root of the 50 ppR tube?.
PP-R also called type three polypropylene pipe and is also called the PP-R pipe or PPR pipe, with energy saving, environmental protection, high strength, corrosion resistance, with smooth inner wall has the advantages of scale, construction and easy maintenance, long service life, widely used in building water supply and drainage, urban water supply and drainage, city gas electric and optical cable sheath, industrial fluid transportation, agricultural irrigation construction, municipal, industrial and agricultural fields. The PP-R pipe is made of random copolymerized polypropylene and is extruded into tubes to be molded into tubes.
No, the first fire water civilian living water, the use of materials and installation are strict requirements, including flanges. Bend. Welding. Threading, require a higher compressive strength. The fire hydrant must be ductile iron pipes must be galvanized steel to withstand corrosion, never to beautiful without change. Otherwise, leave the big trouble.
