Holding high positions among local and global boiler tube suppliers, CSM focuses on liability and quality of its products offering enhanced customization opportunities
CSM water tube for boilers comes in wide range of forms for enhanced customization to satisfy unique heating requirements. Based on the type of heating appliance we can tailor boiler tube lengths according to specific needs, depending on the type of heating appliance being supplied. Diameter range is from 4 up to 28 millimeters and wall thickness ranges from 0.3 up to 1.5 millimeters.
Tailored approach covers also boiler tube materials including AISI alloys with high titanium and molybdenum content. Enhanced nickel alloys or heat-treated piping make CSM water tube in boilers corrosion-resistant and durable to be used with all types of heating fluids.
