Scope of application of cast iron pipes
With the rapid development of my country's construction economy, construction is currently the fastest growing in various cities in my country, so the most indispensable product in these buildings is "cast iron pipe". How much do you know about cast iron pipes? The following is a detailed introduction from Botou Xingrong Cast Iron Pipe Company.
W-type flexible cast iron drainage pipe is a common connection method in our country. It has small radial size (no flange plate), easy layout, space saving, length can be tailored on site as needed, pipe material saving, convenient disassembly and assembly, easy maintenance and replacement, etc. advantage. In addition to the flexibility and good seismic performance of its connection, it also has the characteristics of synchronous construction, high utilization rate of pipes, easy pipe cleaning, reduced hydraulic test times, shortened construction period and improved economic benefits. In addition, this type of interface is fastened with bolts on the outside, which avoids the defects that the flange of the flexible interface of the socket and socket is easily damaged and the bolts against the wall foot are difficult to fix. , with strong competitiveness.
The straight pipe length of the W-type pipe is 3m, which greatly reduces the number of intermediate joints and can be cut to any length as required, thereby saving a lot of pipe materials, reducing consumption and cost. W-type non-socket pipe hoop adopts ribbed stainless steel clamps, lined with rubber rings for flexible connection, high seismic performance, good sealing performance, and is allowed to swing within a certain range without leakage. Therefore, whether at home or abroad, W-type pipes have been widely used. Stainless steel clamp connections are easy to install. Easy to operate and quick to install.
It is suitable for indoor and external pipe diameters of DN50mm~DN300mm and internal pressure of not more than 0.3MPa for socket-type and clamp-type gray cast iron pipes and domestic drainage pipes of matching pipe fittings in new, expanded and renovated civil and industrial buildings. , stormwater pipes, non-erosive industrial production wastewater pipes and rainwater pipes. The standard GB50981-2014 "Code for Seismic Design of Building Mechanical and Electrical Engineering", which was officially implemented on August 1, 2015, also clearly stipulates that "high-rise buildings and buildings in (seismic intensity) 9 degree areas should adopt mechanism drainage cast iron pipes with flexible interfaces".
