PVC pipe is one of the most popular and widely used synthetic materials in the world. Indeed, it is widely used in life, but many people are vague about its specifications. What are the specifications of PVC pipes and national standards? The following Essen PVC pipe manufacturers will explain to you.
What are the specifications of PVC pipes and national standards?
PVC pipe is rigid PVC pipe, which is extruded by hot pressing method after the combination of PVC resin, stabilizer, lubricant and so on. It is the earliest plastic pipe developed and applied. UPVC pipe has strong corrosion resistance, easy bonding, low price and hard texture. However, due to the exudation of UPVC monomer and additives, UPVC pipe is only suitable for water supply system with conveying temperature not exceeding 45 C.
The essence of PVC pipe is a vacuum plastic absorbing film, which is used for the surface packaging of various kinds of panels. So it is also called decorative film and adhesive film, and it is used in many industries such as building materials, packaging, medicine and so on. Among them, building materials industry accounts for the largest proportion, accounting for 60%, followed by packaging industry, and a number of other small-scale applications.
Pvc pipe specifications:
PVC pipe is divided into PVC water supply pipe and drainage pipe, which are used for municipal water supply and drainage, industrial water supply and drainage, civil water supply and drainage, irrigation, vegetation water and so on.
According to Xiaobian, hard PVC pipe has a nominal diameter of 50CM, but the largest soft PVC pipe is generally 50mm.
Specification of rigid PVC pipe: GB/T13020-1991
Specification of soft PVC pipe: GB/T 13527.1-1992
The nominal outer diameters of hard PVC pipe are: 2.5, 3, 4, 5, 6,... 355, 400, 450, 500, 560, 630, 710, 710, 800, 900, 1000, etc. (unit mm).
National Standards for Pvc Pipes:
Standard number: GB/T 8804.2-2003
Standard Name: Determination of Tensile Properties of Thermoplastic Pipes Part 2: Hard Polyvinyl Chloride (PVC-U), Chlorinated Polyvinyl Chloride (PVC-C) and High Impact Polyvinyl Chloride (PVC-HI) Pipes
Standard status: current
Date of implementation: 2003-8-1
Promulgating Department: General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China
Content Description: This standard specifies test methods for tensile properties, especially tensile yield stress and elongation at break. This standard is applicable to PVC-U, PVC-C and PVC-HI pipes for various purposes.
Standard number: GB/T 5836.1-2006
Standard name: rigid polyvinyl chloride (PVC-U) pipes for building drainage
Standard status: current
Date of implementation: 2006-8-1
Promulgating Department: State Standardization Management Committee of the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China
Content Introduction: This part of GB/T 5836 specifies the materials, product classification, requirements, test methods, inspection rules and marks, transportation and storage of extruded rigid polyvinyl chloride (PVCU) pipes, which are mainly made of polyvinyl chloride (PVC) resin.
This part is suitable for drainage pipe in buildings. Considering the chemical and heat resistance of the material, it can also be used for industrial drainage pipe.
The pipes specified in this section are matched with those specified in GB/T 5836.2-2006 "PVC-U Pipe Fittings for Building Drainage"
The above is the introduction of PVC pipe specifications and national standards. The content is only for your reference. I believe you have seen how much you know, hoping to help you.
