Temperature instrument installation is introduced

Temperature instrument installation is what is known to all, temperature instrument installation fixed form can be divided into four kinds: flange fixed installation; Threaded connections fixed installation; Flange and threaded joint fixed installation; Insert the installation simple cases. 1, flange installation is suitable for on the device as well as high temperature, corrosive medium in the low pressure piping installation temperature meter, has wide adaptability, good corrosion resistance, easy maintenance, etc. Flange fixed loading ways of the flange there are five commonly: ( 1) Flat welding steel flange hg - 5010 58 ( Carbon steel) hg 5019 - 58 ( Stainless steel) （ 2) Butt welding steel flange hg - 5014 58 ( Flat butt welding flanges) hg 5016 - 58 ( Concave and convex face welding flanges) （ 3) Flat welding loose tube steel flange hg - 5022 58 ( 4) Crimping loose tube steel flange hg - 5025 58 ( Copper) hg 5026 - 58 ( Aluminum) （ 5) Flange cover hg - 5028 582, threaded connections, fixed generally applies to install thermometer in the no corrosive medium in the pipeline, refining sector also use this type of installation on the device by habit, the advantages of small size, installation of the advantages of more compact. High pressure ( pn22ｍｐa，pn32ｍｐa） Pipe installed on the thermometer thermometer welding casing, belong to the threaded connection installation form, there are fixed and removable casing pipe in two forms. The former used for general medium, the latter for easy to corrosion, easy to wear and need replacement. Thread connection of fixed, there are five inch have 1 & prime; 3/4′ And 1/2 & prime; , metric m33 & times; 2 and m27 & times; 2. Thermocouple with 1 & prime; Or m33 & times; 2 thread fixed, and there is the 3/4 & prime; Thread, individual situation also use 1/2 & prime; Screw fixation. Thermal resistance is multi-purpose inch pipe thread fixed, of which three-quarters & prime; For the most commonly used, 1/2 & prime; Some also use. Bimetallic thermometer fixed screw thread are m27 & times; 2. Pressure type thermometer fixed screw thread is 3/4 & prime; And m27 & times; 2 two kinds. g3/4′ And m27 & times; 2 outside diameter is very close, and can be turned into 1 & quot; 2 clasp, be careful when installing recognize, or wrong welding joint (thermometer Convex sets) The thermometer can not install. 3, flange fixed together with the threaded connection when equipped with additional cases, suitable for corrosive medium in the pipe and equipment installation. 4, a simple case insert fitted with fixed and can change of cutting sleeve type has the casing pipe ( Insert depth adjustable) Two forms, suitable for bar type thermometer on the low pressure pipeline installation as a temporary test. Temperature measuring element most installations in carbon steel, stainless steel, non-ferrous metals, lining or coating of pipe and equipment, sometimes also installed in the brick masonry, PVC, glass, pottery and porcelain, porcelain pipe and equipment such as sugar. Installation and installation of the latter on the carbon steel or stainless steel pipe and equipment are quite different, but with the lining or coating equipment and pipeline basic same, source components are also similar, you can refer to.
