Tianjin cast iron pipe factory direct lowest wholesale prices

Emerging Products Co., sales of cast iron pipe cast iron drainage pipe in recent years, widely used in construction in the drainage system of pipes. The pipe belongs to the metal type centrifugal casting, compact structure, high tensile strength; its uniform thickness and smooth surface; with flexible interface, rubber seals, has a good seismic performance, and it can block noise transmission, the quietest pipeline; the pipes can withstand high temperatures, fire performance, to meet fire safety requirements; it is corrosion-resistant, anti-aging, long service life. Flexible cast iron cast iron drainage pipe is ideal for high-rise buildings and high-rise building drainage pipe. First, the technical characteristics of flexible cast iron drainage pipe installation is simple, flexible, relatively cement twisted mouth method of installation greatly reduces installation labor costs and improve installation speed. At the same time easy disassembly, it is conducive to maintenance, Chaigai and replacement pipes. Easy-to-pipeline trap when correcting the alignment of sanitary ware outlet. Second, the main method of flexible cast iron drainage pipe construction of flexible cast iron cast iron drainage pipe into an interface flange clamp flexible interfaces and flexible primary installation method. Its use is currently on countries with specific regulatory requirements, we combine the product description summarizes its installation and construction methods from the installation process: (a), clamp-type flexible interface installation method, installation should be based on the required length, the straight pipe fixation with abrasive cutter off, vertical section shall, smooth, without flash, burrs, so as not to hurt the rubber seals. 2, with a special wrench or screwdriver clamp connections loosen the clamp bolt, remove the rubber ring, the clamp set into the lower duct. 3, the rubber trap into the lower end of the pipe, the upper tube into the rubber ring, the two interfaces flat for good. Finally, the clamp set into the rubber ring. 4, with a special wrench or screwdriver clamp connection clamp locking bolt, so tight strap securely in place to prevent the tightening force is too large, screw slippage. Second, flexible seismic cast iron drainage specifications and main technical indicators cast iron drainage pipe to length: 1 m, 1.5 m, 1.83 m, 3 m. Pipe main specifications are DN50, DN75, DN100, DN125, DN150, DN200, DN250, DN300. The tensile strength of the pipe ≥150Mpa, hydrostatic testing P≥0.3Mpa, straight tube bend ≤2mm / m. Good seismic performance of the tube, the amount of axial vibration within 2mm pressure 0.1Mpa no leakage, the amount of radial displacement ± 30mm, pressure 0.1Mpa no leakage. Flexible seismic cast iron pipes at the same time with a variety of oblique three, sailing tees, oblique cross, sailing Stone, 90 degree elbow, 45 degree elbow, blind blocking, S-type trap, P-type deposit water bend, and other common stereotypes tapered pipe fittings, ancillary use. Technology and equipment conditions compared to other product attributes metal pipe and plastic pipe, cast iron drainage pipe has some unique advantages, as long as reflected in the high-intensity, low noise, long life, fire retardant, flexible shock, no secondary pollution, Renewable recycling and other aspects. 1, low noise, high strength, long life drain water was not filling and gravity flow state, friction, shock, vibration, noise is inevitable. Graphite cast iron can have a dampening effect on the vibration and prevent vibration energy transfer between grains and convert vibration energy into thermal energy. So cast iron pipe has good noise damping properties. Experimental data indicate that, DN100 pipeline flow 2.7L / s, the cast iron pipe noise is 46.5dB, U-PVC pipe noise is 58dB, it is asking a quiet residential building, schools, hospitals, venue, hotels and other occasions , should use cast iron drainage pipe. Cast iron tensile, flexural strength is four times the usual PVC plastic pipe. The potential of the matrix structure of iron is small, small electrochemical action, while the high silicon content, capable of continuous SIO2 surface protection film, so its performance is far higher than the corrosion-resistant steel, corrosion in the same environment, the medium iron rust resistance is three times more than steel. Cast iron drainage pipe excellent corrosion resistance and strength properties make life much greater than steel and plastic tubing. 2, the flexible seismic cast iron is relatively low coefficient of linear expansion, and thus affected by ambient temperature itself produces a small amount of stretching, while flexible interface structure of cast iron drainage pipe, it has a high resistance to stretching, flexing deformation and seismic capacity, system axial deformation 35mm, lateral vibration Flexing value within 31.5mm interface does not leak. 3, high temperature, fire retardant drain has a through connection characteristics of each floor and the room in case of fire should the drainage pipe fusible, flame retardancy poor, will be formed soon melt fracture kitchen smoke effects. Cast iron pipe retardant and high melting point is that it has good fire retardant. 4, no secondary pollution, renewable recycled cast iron itself does not contain toxic chemicals, no secondary pollution of sewage, waste water, and when the building or drains premium removed, cast iron drainage pipe can be 100% recycled, recycling use. Other Description Product Specification, advantages, features introduced drains the major advantages and technical indicators for the advanced flexible connection, with good seismic performance. 2, using a rubber ring seal, can block sound transmission, it is the quietest pipe. 3, to withstand extreme temperature, fire performance is best. 4, wall uniform, reliable sealing, easy to install. 5. Mechanical Properties: Tensile ≥150Mpa. Transaction Description cast iron pipe factory direct - wholesale prices - Cast iron pipe mechanism
