HELS HLS-50-BKB PIPE EXPANSION JOINTS

Thông tin sản phẩm: 

• Pipe expansion joints are being used in order to absorb expansion and shrinkage movements of heating and hot water pipelines of High buildings. Pipe expansion joints are installed vertically and provides the system to work safely by its bellows.
• There is 3 mm expansion in the pipelines with temperature 90/70 c. The expansion of 7 floor (21mt) building can be
