Piping Support Method Double contained pipe supports outer pipe and elastic slide pipe (sleeve pipe). Intervals differ by size. Refer to the following for intervals. When installing support hardware, be cautious of not tightening nuts excessively. Excessive tightening of support hardware may cause deformation, breakage and leakage (from O-ring, etc. of elastic slide pipe). Use of double nuts or saddle band and utilization of level difference of fitting is an effective way to prevent excessive tightening. For installation of elastic slide pipe, use a pipe platform, etc. as shown below and fix the pipe at a place where there is a level difference of fitting (increaser, end cap) part. At this time, use U-bolt or U-band as steady brace. If providing support above is difficult, support the center of elastic slide pipe and support both ends of outer pipe. At this time, provide support for respective levels as pipe sizes differ between outer pipe and elastic slide pipe. Continuous support which is to support the entire elastic slide pipe with angle or channel is also effective. 2) Fixation of Elastic Slide Pipe 1) Piping Support Intervals
