1. Overview of PPR pipe fittings hot melt connection technology
As a widely used pipeline material, PPR pipe fittings are favored for their excellent sealing and reliability. Hot melt connection technology heats the pipes and fittings, melts them and quickly connects them to form an integrated structure, which effectively eliminates leakage.IFAN factory 30+ years manufacture experience support color /size customization support free sample.Welcome to consult for catalog and free samples.This is our Facebook Website:www.facebook.com.
2. Hot melt connection construction steps
Preparation: First, ensure that the selected PPR pipe fittings and accessories meet national standards and are of reliable quality. Secondly, check the appearance quality of the pipes and fittings, and remove impurities such as oil stains and burrs.
Cutting pipes: Use special PPR pipe cutting tools to ensure that the cross section of the pipe is perpendicular to the pipe axis after cutting, remove burrs and rough edges, and keep the cross section smooth.
Cleaning and drying: The connection end face must be kept clean, dry and oil-free to ensure the quality of the hot melt connection.
Marking the hot melt depth: Use a caliper and pencil to mark the specific depth of the hot melt on the pipe to avoid over-hot melt.
Hot-melt connection: Place the pipe and fittings into the heating sleeve and insert them to the marked depth without rotation. After the heating reaches the estimated time, quickly remove the heating sleeve and push the pipe and fittings evenly into the joint to form a firm and perfect combination.
3. Use of special tools
In the process of hot-melt connection of PPR pipe fittings, the use of special tools is crucial. Special PPR pipe cutting tools can ensure the accuracy and smoothness of pipe cutting; hot-melt connection tools can accurately control the heating temperature and time to ensure the quality of hot-melt connection.
4. Installation precautions
Protect the fittings: PPR pipe fittings should be protected during transportation and construction to avoid mechanical damage.
Ensure tight connection: Ensure that the interface is flat and burr-free during connection, and use special sealant for sealing to ensure that the connection is leak-free.
Control temperature and time: When using electric hot-melt connection, control the heating temperature and time to avoid overheating and heat shrinkage deformation of PPR water pipes.
By mastering the above installation techniques and construction points, the installation quality and use effect of PPR pipe fittings can be effectively improved.
