Plastic pipe specifications

First, pvc pipe specifications, pvc pipe prices

Pvc tube, used in many life, is a popular material in the world that is popular, popular and widely used.

The PVC pipe is a rigid polyvinyl chloride pipe. It is a plastic pipe which was first developed and applied by blending polyvinyl chloride resin with a stabilizer, a lubricant, etc., by hot pressing. UPVC pipe has strong corrosion resistance, easy adhesion, low price and hard texture. However, due to the oozing of UPVC monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45 °C.

The essence of PVC pipe is a vacuum plastic film used for surface packaging of various panels, so it is also called decorative film, adhesive film, used in building materials, packaging, medicine and many other industries. Among them, the building materials industry accounts for the largest proportion, accounting for 60%, followed by the packaging industry, and there are several other small-scale applications.

PVC pipes are divided into PVC water supply pipes and drain pipes for municipal water supply and drainage, industrial water supply and drainage, civil water supply and drainage, irrigation, and watering of vegetation.

Pvc pipe specifications:

The hard PVC pipe has a nominal outer diameter of 50CM, but the soft PVC pipe is generally 50mm.

Hard PVC pipe specifications: GB/T13020-1991

Soft pvc pipe specifications: GB/T13527.1-1992

Hard PVC pipes have a nominal outer diameter of: 2.5, 3, 4, 5, 6, . . . 355, 400, 450, 500, 560, 630, 710, 800, 900, 1000, etc., (in mm).

Pvc drain pipe specification details

The length of the pvc drain pipe is usually 4 meters or 6 meters. If other lengths are required, they can be negotiated with the manufacturer. The nominal outer diameter of the pvc drain pipe is strictly regulated and is implemented in accordance with the national standard GB/T5836.1-2006. The nominal outer diameter of the pvc drain pipe is 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 180mm, 200mm, 250mm, 315mm, 400mm, 500mm, 630mm, etc.

In addition to the standard of pvc drain pipe, its performance indicators must also meet the requirements. The appearance of the drain pipe requires that the inner and outer walls are smooth and smooth, free from bubbles, cracks, depressions, traces, etc., and the color distribution is uniform; the tensile yield strength is greater than 40 MPa; the softening temperature is above 80 degrees Celsius; the result of the drop hammer impact test is less than 10 %.

The wall thickness of the pvc drain pipe has strict regulations. The specific requirements of the outer wall thickness must conform to the GB/T5836.1-2006 standard. The longitudinal retraction rate is less than 5%, and the deviation of the same section cannot exceed 14%.
