Water supply pipe is divided into metal pipe, composite pipe and plastic pipe. Metal pipe is mainly divided into copper and stainless steel water pipe, metal pipe with safety, health, durability and many other characteristics, is the most ideal home furnishing and decoration of the water pipe. Composite tube typical representative of aluminum-plastic pipe, but because of its thermal expansion and contraction problems, has been gradually eliminated plastic pipe is most commonly used PPR water pipe, safe, non-toxic, easy to install, inexpensive, and many other reasons, so that it has become the most commonly used water pipe home improvement. But due to environmental hormones and other issues, more and more people, began to use metal pipe or ppr lined metal pipe as water supply pipe. The various performance indicators of water supply pipe are relatively strict, especially when used for drinking water above, the pipe is required to have non-toxic and non-radiation, can not contain heavy metals and other harmful substances, corrosion resistance should be good, long service life and other requirements. Production of reinforced concrete drainage pipe equipment: mixing system, pipe mold (flat mouth, enterprise mouth, socket, double socket, steel socket), molding equipment (centrifugal machine, roller machine, vertical axial extrusion molding machine, vertical radial extrusion molding machine, core mold vibration hydraulic molding machine, vertical radial extrusion molding machine, core mold vibration hydraulic molding machine, vibration molding device), feeder, steel plate skeleton roll welding machine, hydraulic presses, outside the pressure machine etc. Drainage pipe is divided into concrete pipe (CP) and reinforced concrete pipe (RCP). Drainage pipe specifications are pipe inner diameter DO (100mm - 3000mm), length LO (30mm - 200mm) Pressure index, Class Ⅰ Class Ⅱ Class Ⅲ caliber is divided into: flat mouth, enterprise mouth, socket, double socket, steel socket.
Drainage pipe is made of high-density polyethylene (HDPE) added other additives and the formation of the appearance of corrugated new permeable drainage plastic pipe, water-permeable corrugated pipe is punched through the grooves at the perforation of the outside of the pipe outside the outer perimeter of the outsourcing of needle-punched geotextile processing and become. According to the type of corrugated pipe, it can be divided into single-wall water-permeable corrugated pipe and double-wall water-permeable corrugated pipe. Due to the product's holes in the wave valley and long, effectively overcome the flat round hole products are easy to be clogged and affect the drainage effect of the disadvantages of different drainage requirements, the size of the pipe holes can be 10mm × 1mm-30mm × 3mm, and can be uniformly distributed in 360 degrees, 270 degrees, 180 degrees, 90 degrees, etc., is widely used in highways, railroads, subway projects, Waste landfill, tunnel, green belt, sports field and high water content caused by slope protection and other drainage areas, as well as agriculture, horticulture, underground irrigation, drainage systems. It and soft permeable pipe, plastic blind ditch has become China's civil engineering construction (seepage, drainage) in the three major products. Municipal drainage network depending on the size of the drainage pressure, can choose the double arm corrugated pipe and straight wall pipe. Straight-walled pipe pressure tolerance is stronger, can be used for large-scale drainage and sewage network of specialized pipelines.
