维可牢耐热套管 
Pyrojacket VCO option is the solution to shutting down equipment and 
disconnecting hoses and cables to install heat protective sleeving. 

使用维可牢耐热套管的最大优点，就是在安装热保护套管时，

不需要停用设备也不需要拆卸

软管和缆线。 
The VCO option is factory installed, to ensure correct fit and structural integrity. 
Using high temperature fiberglass thread, a flame retardant hook and loop closure 
is sewn internally. Pyrojacket VCO is adjusted for size, to allow for the overlap 
where hook and loop closures meet. 
维可牢的另一项优点是可以在工厂内现场安装，以确保正确的密合度和结构的完整性。维可
牢耐热套管采用高温玻璃纤维，内部缝合有耐火阻燃的黏扣带。维可牢耐热套管调整至适当
尺寸时，即可利用黏扣带紧密结合。 

yrojacket VCO is available in sizes from 3/4” (19mm) to 4-1/2” (115mm) diameter. 

维可牢耐热套管可供应尺寸为直径 
3/4英吋(19公厘) 至直径 4-1/2英吋(115公厘)。
