The good - warm acceptance

2018-4-12
Currently, warm acceptance from the middle of laying pipe laying heating insulation plays set with heat medium pressure test device installed only by the construction unit in conjunction with the relevant authorities.


(A) low-temperature radiant heating system should be carried out in the middle and final acceptance inspection.


(B) to warm the middle acceptance from laying insulation heating pipe laying play set with a heat medium pressure test device installed only by the construction unit in conjunction with the relevant authorities.


(C) to warm the completion and acceptance by the competent organizational unit construction, supervision, construction and related units jointly. Completion and acceptance should have construction plans and design changes and test report documents the main materials, products and parts, factory certification and inspection records hidden works, intermediate inspection records, pressure test records, quality inspection and assessment records.


(D) to warm the water pressure test steps:


Before a pressure test, pressure test piping and components should take safe and effective fixed and protection measures, water test pressure shall be 1.5 times the working pressure, the minimum of not less than 0.6Mpa.


2 pressure test, the slow manifold injection, while nearly air exhaust pipe. After full of water, and water tightness.


3 water slowly boost, boost time shall not be less than five minutes to work,, after the boost pressure regulator 5 minutes to observe whether the water leakage, pressure up to the required test pressure drop within 10 minutes of not more than 0.03Mpa for qualified.


4 winter when the water pressure test, should take practical measures to freeze.


(E) to the heating pressure experimental steps:


Before a pressure test, pressure test piping and components should be taken to a safe and effective fixed and protective measures, air test pressure shall be 1.5 times the working pressure, the minimum of not less than 0.6Mpa.


2 using the air compressor, through the manifold gradually pressurized, air tightness check.


3 boost to the working pressure, the regulator 5 minutes, without leakage may continue to fill pressure to test pressure, the pressure drop of no more than 5 minutes 0.05Mpa qualified.


(Six) to warm the middle and final acceptance inspection shall comply with the design requirements and technical requirements of this provision, no leakage pipes and components. Valves open and flexible, switching tight before acceptance.


(Seven) to warm the middle and final acceptance inspection shall make a record, sign documents and archives, like essential.
