PRODUCT DESCRIPTION

1.Introduce

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.

5.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.
