Introduction

The products described in this document do not have relevant foreign standards. They are similar to the products specified in CJ/T 183-2008, but differ in design and performance. The performance requirements and application fields are different. In order to facilitate user understanding, the following explanation is given. ---The product described in this document is defined as a steel reinforced plastic composite pressure pipe, which is suitable for plastic pipe systems. It is mainly used in building supply Water, improve the standard system of reinforced plastic composite pipes. When calculating the pressure strength, refer to the pressure strength calculation of aluminum-plastic pipes. The calculation method is used to calculate the pressure bearing strength of the plastic layer and the steel belt layer respectively, and then calculate the overall pressure bearing strength of the pipeline. ---This document specifies the product technical requirements for high temperature peel strength, cold and hot stress resistance of the bonding interface, oxidation induction time, melt quality, etc. The test items include mass flow rate (MFR) change rate, system applicability, etc. The above items mainly focus on the plastic composite pipe system to produce To regulate the long-term application performance of the product. This document specifies the steel reinforced plastic composite pressure pipe for hot and cold water with inner and outer plastics of PE and PP-R (including PP-RCT). Plastic materials such as butylene (PB), heat-resistant polyethylene (PE-RT) and cross-linked polyethylene (PE-X) currently lack reliability verification reports and market Cases of long-term application are not included in this document. However, this does not mean that the above materials cannot be used. With the development of the industry, product selection has More broadly, polybutene (PB), heat-resistant polyethylene (PE-RT) and cross-linked polyethylene (PE-X) are materials with excellent heat resistance. If there is actual application and reliability verification, it will be supplemented and improved in a timely manner. When the product in this document adopts double hot melt connection, the plastic layer bears the axial tension generated by the internal pressure of the pipe, so its installation needs to be considered. The total coefficient (i.e. the ratio of the axial tensile force of the PSP plastic layer to the axial thrust generated by the static pressure inside the pipe) is used to ensure that the adhesive layer of the pipe is In the event of accidental delamination, the plastic layer has sufficient tensile strength to ensure the long-term safety of the pipeline system. When calculating the size, different safety factors were selected. The larger the safety factor, the thicker the plastic layer, the greater the tensile strength, and the higher the system safety. Select products with different safety factors according to different usage requirements. Steel reinforced plastic composite pressure pipe for hot and cold water

1 Scope
