Construction inspection of IPS(PPH) pipe and fittings welding

What inspection shall be carried out for the welding of IPS(PPH) pipe and fitting IPS(PPH) pipe and fittings hot melt socket welding construction inspection mainly for the appearance inspection, including the following: 1. Whether the socket and socket are aligned; 2. Whether the extruded molten material between socket and socket is consistent on the whole outer circumference; 3. Peel off the contact surface and observe whether there are impurities, shrinkage holes, cracks or other injuries in the welding area; 4. Observe whether there are [...]

3 step hot welding of IPS(PPH) pipes and fittings

3 step hot welding of IPS(PPH) pipes and fittings 1. Welding machines and tools IPS(PPH) pipe and fittings welding for hot welding, using various specifications of hydraulic or manual plastic pipe hot welding machine. Taking the hot-melt welding machine of hydraulic plastic pipe as an example, welding is mainly divided into three parts: welding control platform, welding operation platform and tool placement rack. 2. Prepare for welding For the pipe cutter (pipe cutter), acetone and clean cloth matching the IPS(PPH) pipe model, the [...]

How to improve the hardness of PVC pipes and fittings?

How to improve the hardness of PVC pipes and fittings? 1、 How to improve the hardness of PVC pipes and fittings? 1. The plasticization of PVC pipes and fittings must be high, and the plasticization should be as high as possible. As long as the decomposition does not change color, the plasticization can be properly improved, making the relative high point of the material’s dilute softness. 2. The cutting pressure of PVC pipes and pipe fittings should be placed at the die [...]

Why PPR pipes and fittings are brittle at low temperature

Why PPR pipes and fittings are brittle at low temperature? PPR pipes and pipe fittings are brittle at low temperature, and will break under external impact or heavy pressure. So what are the causes of this and how can we prevent it? 1. What is low temperature brittleness? The impact absorption energy of materials (all materials, including metal materials and non-metal materials) decreases with the decrease of temperature. When the test temperature is lower than TK (critical transition temperature of toughness [...]
