Shanxi Xuan's cast iron pipe pieces wholesale

Cast iron pipe scope for new construction, expansion and renovation of civil and industrial buildings interior and exterior diameter is DN50mm ~ DN300mm, the internal pressure of not more than gray cast iron pipe and related fittings 0.3MPa the socket type and clamp connections life drains, storm sewers, no erosion of industrial wastewater pipes and Yula tube. Features cast iron pipe: Compared with other metal pipe and plastic pipe, cast iron drainage pipe has some unique advantages, mainly in the high-intensity, low noise, long life, fire retardant, flexible shock, no secondary pollution, recycling of other aspects. 1, low noise, high strength and long life. Drain the 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. 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. We are adhering to the "casting honest and hard" business philosophy, focusing on pre-sale, sale, sale and service of all sectors, the implementation of "user worry-free service works." Xuan's people committed to build the company into a world-class large-scale enterprise founder, adhere to the "quality, price, service" three excellent approach to win the market, with new and old customers and common progress.
