A straight pipe 300mm at least shall be provided on inlet side of branch pipe. Space between branch
pipes must be kept at 800mm or more. Space between two bending points shall be kept at 800mm or
more. Space between branch pipe and bending point shall also be kept at 800mm or more.
☆
On air pipe side, heat preservation materials
which are
able to endure 120 or a higher temperature
℃
shall be used for heat preservation of branch pipe. Do not use the foam on branch pipe as the material
for heat preservation. To prevent liquid pipe from leaking, it is required to connect the two types of heat
preservation materials end to end, i.e. the foam material on branch pipe and the heat preservation
material used on site. After that, wrap up the joints between the two types of materials.
