This paper analyzes the difference between PVC-U pipe and UPVC pipe from three aspects.
First, the characteristics:
1, upvc pipe is also called hard polyvinyl chloride pipe, u-pvc pipe, is a strong corrosion resistance, acid and alkali salt oil medium erosion, light weight, a certain mechanical strength, good hydraulic conditions, easy to install, but Easy to aging, high temperature resistance, but can not withstand impact, suitable for domestic water system, pipe fittings below DN50, more than DN65.
2, pvc-u tube, also known as rigid polyvinyl chloride tube, is a new type of drainage pipe which is extruded by extrusion machine with smooth inner wall and vertical reinforcing rib on the outer wall. It is suitable for residential drainage system. "T" rubber ring interface.
Second, the design selection angle:
1. PVC-U is mainly used for building water supply and drainage, light and durable, beautiful color, smooth and smooth, anti-aging, long service life, excellent physical and chemical properties, chemical corrosion resistance and high impact strength.
2. The anti-freezing and heat-resisting ability of UPVC pipe is not good. Anti-drying performance is good, corrosion resistance is strong, fluid resistance is small, mechanical strength is high, hygienic is non-toxic, water tightness is good, PVC pipe is suitable for electric wire pipe and sewage pipe And installation of large overhead pipelines with low strength requirements, such as power plant cooling towers.
Third, the construction angle:
1. PVC-U is mainly used for building water supply and drainage, pre-embedded line pipe, the main method of construction is hot-melting, glued, and difficult to construct in winter.
2. UPVC is used for building water supply and drainage, sewage pipe, can replace ordinary cast iron pipe, galvanized pipe, easy to install, can be installed with flange and corresponding kit, construction has no limitations.
