Quality cast iron pipe elbow wholesale supply Beijing

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. Product Attributes centrifugally cast pipes and fittings Technical Specification 2.2 Quality Assurance 2.1 pipes and accessories design, manufacturing, testing and the performance indicators in full compliance with the following standards:. GB / T12772 "flexible interface cast iron drainage pipes and fittings" CJ / T177 "building housing type cast iron drainage pipes and fittings" CECS168 "building drainage flexible interface cast iron pipeline engineering point of order" 2.2 products should be made product testimonials centralized test unit authorized by the state or internationally recognized test station issued. 2.3 You must have a complete quality management system and advanced technology and perfect test equipment. Response: light spectrometer, thickness detector, hydrostatic testing equipment, tensile strength testing machine. 2.4 factory production of centrifugal cast iron pipes must have the ability to test a full-factory routine and special tests. There. 3. Provide the necessary information technology and other equipment described circumstances existing main production units are as follows: (1) 105㎡ ring sintering machine, one Taiwan, 616m3 blast furnace, with an annual 800,000 tons of hot metal; (2) DN80-1000MM cooling metal centrifuge 5, DN1000-1600MM heat molding centrifuge 2, with an annual production capacity of 400,000 tons; (3) welded flange pipe production line, the annual production capacity of 10,000 tons; (4) DN100-1000MM special spraying pipe production line 2, the annual production capacity of 50,000 tons; (5) DN50-300MM drain electrostatic spraying production line one, the annual production capacity of 20,000 tons; (6) cast pipe production line, annual production capacity of 20,000 ton; (7) Major public auxiliary facilities: 1500 Nm3 / h oxygen machine, 30,000 m3 / h gas tank 1.
