Cast iron pipe fittings for building drainage tee Tianjin various models of cast iron pipes

Emerging Pipeline Limited production and sales of 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.
