WSS Mastic Wraparound Heat Shrinkable Sleeve Inner Diameter 50 -
3200MM , Material PE
1. Product Introduction
WSS(M) series of mastic heat shrinkable wraparound sleeves are
consist of a radiation cross-linked heat shrinkable backing coated
on the inside with a mastic adhesive. While the modified
polyethylene material of the backing offers superior mechanical
protection, the specially formulated adhesive offers excellent
corrosion protection under demanding conditions.

4. Purchase Guide
Example: WSS(M)50Φ219x500-1.2/1.0 (mm)
1, WSS(M):Product code,measure unit:PC,Roll or M2.
2, 50:Operating Temperature.
3, Φ219:Suitable steel OD,range: Φ114-2200mm.
4, 500:Sleeve width,range 50-720mm.
5, 1.2:Backing thickness,range:1.0-1.5mm.
6, 1.0:Adhesive thickness,range:0.8-2.0mm.
WSS(M)50& WSS(M)80 sleeves can be delivered as kits or in roll form
e.g “30M”. Each factory assembled kit will consist of one sleeve,
suitable for a particular pipe size, a separate closure seal.If the
pipeline steel is coated a insulation layer such as 30mm
thickness,we need to recalculate the pipeline OD and sleeve
length,even closure width sometimes,e.g: pipeline
OD:219+(30x2)=279. In the event of ordering sleeve rolls, closure
seals can be ordered separately.
