Hash pH meter, Takhar environmental (certified), hash

 6.1.1 General provisions pipe installation shall meet the following conditions: 6.1.1.1 and pipeline-related civil works have been inspected and meet the installation requirements, and has been handing. 6.1.1.2 machinery and pipe connections have to find positive qualified, fixed completed. 6.1.1.3 piping components and pipe supports, have been inspected. 6.1.1.4 pipes, fittings, valves, etc., internally clean, free of debris. Within the possession of the special requirements of the pipeline, its quality has been consistent with the provisions of the design documents. Such as degreasing, internal corrosion and lining 6.1.1.5 related processes must be completed prior to the installation of the pipeline has been completed. 6.1.2 flanges, weld and other connections should be set for easy maintenance, and not close to the wall, floor or rack. Piping components 6.1.3 degreased hash turbidity, must be strictly checked before installation, without traces of oil pollution. 6.1.4 pipeline crossing the road, when the wall or structure, should be added protective sleeve or masonry culvert. 6.1.5 buried pipeline corrosion Houha Xi pressure test shall promptly backfill, compaction layered hash pH meter, and "(closed) record covert project" form to fill in Section A.0.4 A provision of this Code section shall appendix , for the hidden works acceptance. Should be measured hardness values ??of the weld and heat affected zone of the weld heat treatment requirements after heat treatment, the hardness value should be consistent with the design documents. When the design documents without clearly defined, the carbon steel should not be greater than 120% of the base material hardness; alloy steel base metal hardness of not more than 125%. Number of tests should not be less than 10% of the total weld heat treatment. 7.4.9 hash pipe welds requiring heat treatment line analytical instruments, should fill in the Appendix of this specification, "Heat Treatment Report" A Section A.0.7 stipulates that format. 7.5.1 pipeline installation, after heat treatment and non-destructive inspection, pressure test should be carried out. Pressure tests shall meet the following requirements: 7.5.1.1 pressure test shall liquid as the test medium. When the design pressure of the pipeline is less than or equal to 0.6MPa, the gas can also be used as a test medium, but should take effective security measures. Do not use gas brittle material pressure test. Hash pH meter, Takhar environmental (certified), hash provided by Suzhou Electrical Equipment Installation Engineering Co. Deco.
