solution for a wide range of liquid transportation. The advantages of VESBO  It is not allowed to distort and break the pipeline during assembly.
PERT over other plastic and metal piping systems, such as high operation  Pipes that are transported and stored under 0 ° C, should be kept
temperatures, non-corrosiveness, flexibility, higher impact strength at lower at a temperature not exceeding 10 ° C for 24 hours before being
temperatures and speed of installation, are considered the main reasons transferred to production.
for being preferred by engineers for residential and industrial projects.  Pipe ends should be closed with plugs to prevent pipe
contamination and dusting.
 When bending the pipe (maximum radius of 5D outside), it is
recommended to preheat the pipe to 130 ° C with a dryer. The
Material : Raised temperature polyethylene (PE) with pipe must be bent using a spring conductor.
advanced polymeric structure
 When heating the pipe, the pipe should be fixed to rotating points
and 10 cm gap should be left with clamps to prevent the bent part
