Brugg Pipes

Sleeve joint

1. PE shrink sleeve, non-cross-linked

The non-cross-linked shrink sleeve consists of a heat-shrunk PE sleeve

pipe and the following accessories:

- Shrink-on collars

- Permanently elastic sealing strip, butyl rubber

- Venting plug

- Welded-in PE plug

The shrink sleeves are pushed onto the casing pipe when the pipe is

being laid, before the medium pipe weld seams are made. The connec-

tion points are then fitted with additional insulation by trained fitting

staff who have been tested as per AGFW Worksheet FW 603.

This produces a watertight, non-positive connection between the

casing pipe and the sleeve. The sealing strip and the shrink-on collars

are used to double-seal the sleeve joint. Technical requirements as per

EN 489, AGFW Worksheet FW401, parts 6, 14, 16 and 17.

Nominal width:

90 ... 1200

Length:

700, 1000, 1400 mm

2. Shrink sleeve made of cross-linked PE

The cross-linked shrink sleeve consists of molecular cross-linked poly-

ethylene, so only limited welding is possible. The very high shrinkage

capacity of this material combined with the sealing strip inserted

between the casing pipe and the sleeve produce a very strong non-

positive connection.

Because this type of sleeve can withstand high mechanical loads, it

is especially suitable for plastic casing pipe sections that are subject

to higher stresses (e.g. frequent load alternation, pipes laid in the

groundwater zone).

Nominal width:

90 ... 1200

Length:

700 mm
