Pivoted Roof Drain System This is the simplest roof drain system available. It is easy to installand is very cost effective. Using in conjunction with the pivoted joints are standard API Sch. 40 pipes, ANSI #150 RF flanges and spiral wound stainless steel metallic gaskets. The pivoted roof drain system can be perceived as a combination of a flexible hose system and a rigid pipe system, offering the unique advantages of both systems without their short comings. Swivel Joint Drain System The swivel joints have been used for many years in external floating roof drain system. The joints are normally connected to API Sch 40 pipes to form a roof drain system. Though robust in design, its seal packing need to be periodically checked. |
