Shandong ductile tube manufacturers introduce the new flexible interface ductile iron steel pipe features that are commonly used in the world, and have no socket joints and straight pipe and pipe fittings (this article focuses on the introduction of a new type of flexible interface ductile iron pipe and fittings), according to its interface type Type A flexible interface (Flange gland connection) and W type flexible interface (tube hoop connection), referred to as A type and W type. Single Lever Bath-Shower Mixer 1. Bathtub faucet: It is installed above the side of the bathtub and is used to open hot and cold mixed water. Those that can connect two hot and cold pipes are called duplex; The structure of opening and closing water flow includes spiral lifting type, metal ball valve type, ceramic valve core type, etc. At present, there are more ceramic valve spool single-handle bathtub faucets on the market. It uses a single handle to adjust the water temperature and is easy to use: the ceramic spool makes the faucet more durable and watertight. The valve body of the bathtub faucet is mostly made of brass, and the appearance is chrome plating, gold plating and various metal paint.

The new flexible interface ductile iron pipe adopts high-speed centrifugal casting technology. It has compact structure, uniform thin wall thickness, smooth inner and outer walls, no trachoma and slag inclusion, high tensile and compressive strength. The product has stable chemical composition, corrosion resistance, and no fire. Poison, fire safety and environmental protection requirements, no noise, no deformation, long life advantages.
A-type pipe: A type pipe has the advantages of high strength, low noise, good fireproof performance, long service life, flexible connection and good anti-seismic performance, but the installation space required for socket joints is found in actual projects. It is large and heavy and consumes more steel. It is difficult to be accepted by construction parties especially in high-rise buildings.
W-type pipe: W-type pipe in addition to the same high strength, low noise, good fire performance, long service life, its connection flexibility and good seismic performance characteristics, but also has the ability to synchronize construction, high pipe utilization , Easy to clear the pipeline, reduce the number of water pressure test, shorten the time period to improve the economic benefits characteristics. In addition, the interface of this type of ductile iron pipe is bolted to the outside to prevent the flange of the flexible socket of the socket from being easily damaged by the flange and the bolts of the footwall being difficult to fix. The utility model has the advantages of easy operation and the like, therefore, the building drainage pipe and the pipe fitting In the selection, it has strong competitiveness.
In addition, because the length of the W-tube straight tube is 3m, the number of intermediate joints is greatly reduced and any length can be intercepted as required, thereby saving a lot of pipes, reducing consumption and costs. W-type no-mouth pipe clamps use ribbed stainless steel clamps with flexible rubber-lined connections to provide high shock resistance and good sealing performance. Swing is allowed within a certain range without leakage. Therefore, W-tubes have been widely used both at home and abroad.
