There are many types and materials of water pipes on the market. Many friends may not know how to choose water pipes. In fact, the scope of application of different water pipe paint is not the same, so before the choice must be carefully considered, according to their own use of the location to choose. So...pvc-upipe andpvcWhat difference does it make?pvcWhat are the specifications of the tube? Let's take a look.

pvc-upipe andpvcWhat's the difference

pvc-uTube andpvcThe tube is the same.UPVC, also calledPVCUIt is often called hard.PVCare made of vinyl chloride monomer and certain additives(Such as stabilizers, lubricants, fillers, etc.)Polymerization of amorphous thermoplastic resin.).).In addition to additives, it is also modified by blending with other resins, which has obvious practical value.

1.These resins includeCPVC,PE,ABS,EVA,MBSWait.UPVCHigh melt viscosity and poor fluidity. Even if the injection pressure and the melt temperature are increased, the fluidity does not change much. In addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the molding temperature range is very narrow, and it is a material that is difficult to mold.

2.U-PVCWinding pipe, also known as double flat wall steel plastic composite winding pipe, is now a new technology. Compared with cement pipe, it has its own advantages.

What is the specification of PVC pipe

PVCAccording to the different performance of the tube can be divided into softPVCtube and rigidPVCTube. The main difference is whether they contain plasticizers. Soft PVC pipes have problems such as weak physical properties and cannot withstand certain water pressure. Therefore, soft PVC pipe is usually used for ceiling, floor and leather surfaces, and is often used as a conduit.

1.Rigid PVC pipes do not contain plasticizers, are easy to shape, and have excellent physical properties during the production process. Rigid PVC pipes are usually used as drainage pipes and water pipelines, and have great development and utilization value.

2.The market share of soft PVC pipe is only 1/3, and the market share of rigid PVC pipe is 2/3.PVCThe raw material of the tube is not completely thin, but environmental additives can be used to make it a non-toxic and tasteless environmentally friendly product.

3.The size of PVC pipes should be distinguished according to their types, and the nominal outer diameters of different types of PVC pipes are different.PVCThe large nominal diameter of the hose is50 mmIt usually does not exceed this size. In addition, the nominal diameter of the rigid PVC pipe can be larger, even50Centimeters.

4.The size of soft PVC pipe conformsGB/T13527.1-1992, rigid PVC pipe size conformsGB/T13020-1991. Commonly used are2.5mm,3mm,4mm,5mm,6mm, etc.

If you want to buy water pipes, it is recommended to go to the local regular building materials market and choose the products of regular manufacturers, so that the quality is more guaranteed. The above is aboutpvc-upipe andpvcThe difference between the tube, andpvcThe relevant specifications of the tube. When buying water pipes, you must pay attention to the purchase method and choose pipes with guaranteed quality.
