Beijing cast iron drainage pipe pieces wholesale

Introduction of flexible cast iron pipe known as: cast iron pipes, flexible seismic cast iron drainage mechanism of cast iron pipes, cast iron pipes flexible connection, centrifugal cast iron pipes. 2 classification from the pipe system structure, cast iron drainage pipe can be divided into straight pipes, fittings, accessories three categories. Seen from the interface can be divided into: W-type flexible cast iron pipes, B-type flexible cast iron pipes, A type of flexible cast iron pipes. From the material up points: ductile iron drain, gray cast iron pipes. 3 elements of W-type flexible cast iron pipes are commonly used in China connection, having a small radial dimension (Flanges), easy layout, save space, cut length can be set as needed in the field, saving pipe, easy accessibility, ease maintenance and replacement and other advantages. Good performance can flex and seismic characteristics of their connection, but also having a simultaneous construction, pipe utilization, easy to clean through the pipeline to reduce the pressure test times, shortening the construction period to improve economic efficiency characteristics. In addition, this type of interface to the outside of the fastening bolts to avoid flange socket flexible interface is easy to damage, difficult to fix the bolt foot wall defects, with the advantages of easy operation, and therefore the construction of drainage pipes and fittings in selection , with a strong competitive edge. Furthermore, since the W-tube straight tube length 3m, greatly reducing the number of joints and in accordance with the middle need to intercept any length to save a lot of pipes, reduce consumption and costs. W - type socket ferrule using ribbed stainless steel clamps, rubber lined ring flexible connection, high seismic performance, good sealing performance, allowing swings within a certain range and will not leak. Therefore, whether at home or abroad, W-tube have been widely used. Stainless steel clamp connections for easy installation. Easy to operate, quick to install. 4 Features Benefits 1. Low noise, high strength and long life. 2. Flexible earthquake. 3. High temperature, fire retardant. 4. No secondary pollution, renewable recycled. 5. The flexible interface drainage has strong anti-flexing, stretching deformation and seismic capacity, has broad applicability. 5 standard W-type flexible cast iron pipes: GB12772-2008 6 diameter Φ50, Φ75, Φ100, Φ150, Φ200, Φ250, Φ300 7 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 0.3MPa socket type and clamp connections gray cast iron pipe and related fittings life drains, storm sewers, no erosion of industrial wastewater pipes and Yula tube. 8 pieces chosen Currently many manufacturers of flexible cast iron pipes, W-type cast iron pipe manufacturers product quality and performance is uneven. Select the appropriate specification in accordance with the manufacturer is always to ensure the smooth progress of construction, but also the construction after the completion of the warranty period to facilitate the maintenance of one of the foundations. 9 Installation Guidelines 1. First ground, after the ground; 2 first bassoon, after a small tube; 3 first director, after the branch pipe. 10 Note 1, W-tube connected to the pipe using the flat high quality requirements, the outer diameter of the cast iron drainage pipe ovality, wall thickness and physical properties of the rubber ring have higher requirements. 2, W-tube installation and construction should be strictly in accordance with operating procedures. Especially in the straight pipe installed at each of the nipple required riser card riser fixed on the load-bearing walls of the building; horizontal pipe at each interface should be added to set hanger.
