Pipes are connected with spigot-to-spigot with stainless steel sleeve as a bridge between pipe end. EPDM rubber ring mounted on both spigot as permanent seal against leakage. Wood cushion board place between each pipe as jacking force distributor during installation. Connected joints are tested and proven to withstand minimum 4 bar hydrostatic pressure both internally and externally. During installation, user is required to align and push-to-insert spigot end into the stainless steel sleeve.
Pipes inner surface may coated with additional layer of liner as finishing touch. Color can be customized as per user preference.
Packing service is available and being practiced for pipes with inner diameter of 300 or below. All TPP pipes are delivered with EPDM rubber ring secured with adhesive and wrapped with layers of films to avoid unnecessary damage and foreign object affecting joint performance. This is our effort to diminishing defective during transport related activities while expediting the whole process: delivery-to-installation in quick and safe manner.
To put ourselves in customer’s shoe, we have come out with a convenient and effective way. We will have the rubber ring glued and fixed in advance, after that, wrapped with a layer of black anti-ultraviolet material so that the rubber ring is well protected from the ultraviolet radiation.
