Butt Fusion
Insert a heater plate between the sections of a tube or joint and removing a heater plate after melting the sections of a tube or joint. After that, applying sufficient pressure after contact the melted section of each product. At this time, worker have to comply with temperature, pressure, and time.
Socket Fusion
Insert a heater face and attached heater face to fitting’s inner side and pipe’s outer surface and removing both of heater face after melting the product’s inner side and outer surface. After that insert the product to each. it is suitable for under 75mm pipe
Screw Type Jointing
It is jointing method through insert pipe between fittings and tighten the cap and body. Since it is one of the easy and perfect jointing method, It is used for waterworks piping. It is suitable for under 100mm pipe
