Salling Plast produces different types of assembly T-pieces which are used for repairing or establishing new service lines, often on systems in operation by way of a hot tapping valve.
Our assembly T-pieces fulfil the technical requirements stated in EN253.
In principal an assembly T-piece can be divided into three parts: a main pipe a branch piece an accessory kit
These parts can be supplied singularly, combined or as a complete set.
5.1 Combinations These standard combinations can be supplied with in a few days. All combinations except assembly T-piece with flanges can be delivered with a double branch: Assembly T-piece with flanges Assembly T-piece with loose flexbranch, complete Assembly T-piece with welded flexbranch Assembly T-piece welded, shrinkable branch Assembly T-piece with welded flexbranch and oversized collar
5.1.1. Assembly T-Piece with Flanges The main pipe is shrinkable in both ends. The main pipe collar, which is also shrinkable, is integrated with the main pipe. The adhesive for the main pipe is sent loose and cut to size.
The branch is a flexbranch (0-90°) with a shrinkable casing with adhesive.
The main pipe is available for dimensions Ø110 up to Ø315 mm and the branch for dimensions from Ø63 up to Ø140 mm.
Both the main pipe and the flexbranch in all dimensions have been subjected to irradiation, which reason expansions plugs are needed.
The branch piece consists of steel flanges with nuts, adhesive for flanges and the main pipe, ventilation plugs, expansion plugs and fops.
The steel part consists of steel bends and centerrings.
The assembly T-piece is tested according to EN489:2003.
Report can be obtained.
Mounting manual can be obtained.
