ERA Plastic PVC/UPVC Pressure Pipe Fitting/Joint BS4346 Female Adaptor/Coupling with KITEMARK CertificatenPVC pipe featuresn(1). The surface hardness and tensile strength of the pipe are excellent, and the pipeline safety factor is high.n(2). It has good aging resistance and its normal service life can reach more than 50 years.n(3). The pipeline has excellent corrosion resistance to inorganic acids, alkalis, and salts, and is suitable for industrial sewage discharge and transportation.n(4). The friction coefficient of the pipeline is small, the water flow is smooth, it is not easy to be blocked, and the maintenance workload is small.n(5). The material has a high oxygen index and is self-extinguishing.n(6). The linear expansion coefficient of the pipeline is small, 0.07mm/℃, and the deformation due to temperature is small. The thermal conductivity and elastic modulus are small, and compared with cast iron drainage pipes, they have excellent freezing resistance.n(7). Pipes and pipe fittings can be connected by bonding. The construction method is simple, the operation is convenient, and the installation efficiency is high.n(8). Good water tightness: The installation of PVC-U pipes, regardless of whether they are connected by bonding or rubber rings, has good water tightness.
