SpeedFlex NBR Insulation tube
In todays competitivness to insulate pipes to prevent heat loss in heating and in air conditioning making sure when you need chilled air is not lost outside.
The standard for this excelent insulation tube (GB/T17794-1999) we now offer separate or pre-insulated with our 304 stainless steel flexible pipe for use in the Chinese solar water heating industry supplied with a roll of PE film UV protective tape for covering the exposed insulation tube outside, as no need for inside protection.
The majority of Solar Water heating system combinations do not produce hot water above 90c even on a blue sunny day. This qaulity selected Chinese manufactured tubing we have selected for our Solar SpeedFlex range we recomend to any company installing such system and those importing from Chinese manufactures of which very few offer a plumbing system kit, which enhances the performance of their tested equipment through as often is a western testing centre for solar key mark and SRCC in the USA where copper or Flexible stainless in the correct bore size is used.
We are now taking orders for containers of this insulation tubing only in a wide choice of insulation tube thickness and ID separate to the stainless steel Ningbo bare pipe coils.
