essary from any recognized body/aut hority during manufacturing of high-pressure ells, the same shall have to be arranged by the Supplier. 1. The thermowell immersion depth () shall be sufficient to elimi nate conduction error. general rule which may be followed is to use an immersion length equaling minimum of 1 times the diameter of the protective ube or well. In general, immersion length of thermowells for different line siz follows: Line Size Insertion Len gth () From 4 to 6 2 mm From 6 & onwards 3 mm Vessels 4 mm Immersion length is based on 2 mm length between flanges face and inner wall of pipe. In vessels, where fouling with vessel internals is exp ected, the immersion length shall be suitably modified. Any pipeline less than 4 no minal bore shall be blown to 4 size. .7 Resistance Temperature Detector (RTD) with Thermowell 1. RTDs shall be duplex, platinum three ( wire nominal resista nce of pt1 ohms at 0 Deg and conform to DIN 4 / BS 1. 2. Stability of RTD over full range shall be better than 0.0 ohms and the repeatability figure shall be better than 0.0 ohms. Accuracy shall be of the order 0.1% or better and response time shall be less than 2 seconds with thermowell. 3. The protective-sheath material shall be SS 3, seamless tubes using compacted magnesium oxide packing for insulation. The insulation resistan ce at 5 0C shall not be less than 5 mega-ohms. 1 of 1 INDRADHANUSH GAS GRID LIMITED TECHNICAL SPECIFICATION FOR NATURAL GAS COMPRESSOR STATION FOR NORTH EAST GAS GRID PIPELINE PROJECT TS NO.: MEC//2UU/0/2/0 Control & Instru mentation (&) Chapter-0.0 2, MECON Limited, All Right Reserved Page 3 of 1 4.
