Introduction:
1) SS141 CLASS B / CLASS C – GREY
These pipes are commonly used as cable conduits and have excellent di-electric strength because of their insulation properties. They are produced in socket end to facilitate ease of joining and installation.
2) SS141 CLASS D / CLASS E – WHITE
These pipes have the working pressure ot 12 to 15 Bar. (1.2 to 1.5MPa). This allows pipes to be fitted to mechanical equipment such as pumps, cooling towers, etc. They are also used in conjunction with mechanical machinery in factories. Theses pipes can be used for conveying cold water to household and for irrigation purposes because it does not import any odour, taste, colour or any toxic constituents in concentration that can be harmful to health.
