3 Versatility and Price ALLOY has the capabilities of meeting all of your Thermowell requirements whether they be a single piece or very large contract jobs at a competitive price. Sales ALLOY maintains ample finished and semi-finished stock levels to serve distributors, located throughout the USA and Canada. An expedited delivery service is available upon request. Engineering This catalog gives complete engineering information for the proper selection of Standardized Thermowells. ALLOY s engineers are willing and able to help with any design problems. Manufacturing Equipment All wells are machined from solid bar stock on the most modern numerical control machines. Bores are produced on deep hole gun drilling machines which produce smooth true holes accurately centered in the sensitive part of the well. Expense connected with thermowell selection does not end with the initial purchase. Listed below are some of the reasons for the careful dimensioning of the Thermowells in this catalog. Note the emphasis on standardizing of bore size, element (or stem) length and other internal dimensions. You will discover other benefits to using standard wells as time goes on. Save On Initial Investment Standard wells are produced on a large quantity basis bringing about reduced cost and improved delivery. Temperature sensing elements are lower in cost since you are buying larger quantities of particular sizes. Gain Overall Flexibility A temperature sensing element in a threaded well also fits a flanged well downstream, or a socket weld well on main steam. Pull out a Bi-metal thermometer and insert a test thermometer or thermocouple in that same well. Since these wells accept several types of sensing elements, instruments may be swapped around to suit changing optional procedures or advancing technology. Reduce Spare Instrument Inventory Use of standard wells throughout the plant can reduce the number of spare instruments necessary to insure safe coverage. Less work is required by the power plant designer in establishing a recommended spare list. Why Standard Thermowells? Minimize Down Time Even if caught without a spare, chances are that an instrument, in a less critical location can immediately be relocated to a measurement point where a failure has resulted. 3

4 Selection of Thermowells Material - The Longevity Factor In general, the thermowell material chosen for the installation is governed mainly by the corrosion conditions the well will face. Recommended materials for various services are given in the Corrosive Service Guide on page 23. The high polish given to all stainless and monel wells provides maximum corrosion resistance and strength. Occasionally, the material consideration is one of strength rather than corrosion. For example, a stainless steel well may be required for high pressure water service where otherwise a brass well would be satisfactory from a corrosion standpoint. Consult the pressure-temperature ratings given for each well type. The standard materials listed for each well series will cover most requirements. Alloy carries a wide variety of special materials in inventory to insure fast delivery of wells. Materials include special grades of Stainless Steel, Chrome-molybdenum, Steel, Naval Brass, Hastelloy B&C, Nickel and Titanium. Connection - The Installation Factor In these pages you will find standardized wells of threaded, flanged (A.N.S.I. and Van Stone) and socket weld types with standard bore sizes. Threaded wells are all made in readily welded or brazed materials. This is important for installations requiring seal welding or brazing. The pipe thread provides the mechanical strength, the weld merely seals. Flanged wells (other than Van Stone type) consist of a bar stock well which is solidly welded to a top quality flange. Standard construction uses a primary J groove weld and a bevel groove secondary weld. Both welds are machined to produce a clean fillet. This double welded construction eliminates possibility of crevice corrosion and stress problems since no open joints are exposed from either inside or outside the installation. Socket welding types of wells are simple to install by merely welding into place. These wells fit A.N.S.I. standard socket weld couplings or flanges. The resulting installation is clean and tight. Insertion Length - The Accuracy Factor The distance from the end of the well to the underside of the thread, or other connection means, (designated as U ) is the insertion length. For best accuracy, this length should be long enough to permit the entire temperature sensitive part of the thermometer bulb to project into the temperature medium being measured. 4

5 A properly installed thermometer bulb will project into liquid an amount equal to its sensitive length plus at least one inch. In air or gas, the bulb should be immersed to its sensitive length plus at least three inches. Thermocouples and thermistors have short sensitive lengths, therefore can use the smallest insertion lengths. Bi-metal thermometers, resistance thermometers and liquid-in-glass thermometers have bulbs with sensitive portions between one and two inches long. Therefore, the minimum standard insertion length of 2 1/2 must be entirely immersed in liquid for proper accuracy. Filled system thermometer bulbs may have sensitive portions from one to several inches in length. Determine the sensitive length of the bulb before choosing an insertion length. Above all - be sure that dead length, ie. - that are required to pass thru walls, pipe fittings, etc., is taken into account when choosing the necessary well insertion length. Bore Size - The Interchangeability Factor Almost any installation uses several types of temperature measuring instruments. The selection of a standard bore diameter can produce maximum flexibility within the plant. The same well can accommodate either thermocouple, resistance thermometer, bi-metal thermometer, or test thermometer. The bore size of wells shown in this catalog cover the most commonly used temperature sensing elements as follows:.260 Diameter Bore: Bi-metal Thermometers ( Stem) Thermocouples - (#20 Gauge) Liquid-in-glass Test Thermometers (unarmored) Other elements having.252 maximum diameter.385 Diameter Bore: Bi-metal Thermometers (3/8 Stem) Thermocouples - (#14 Gauge) Liquid-in-glass Test Thermometers (armored) Other elements having.377 maximum diameter Tapered or Straight Shank - The Velocity Rating Factor Tapered shank wells provide greater stiffness for the same sensitivity. The higher strength-to-weight ratio gives these wells a higher natural resonant frequency than for an equivalent length straight shank well, permitting operation at higher fluid velocities. Refer to Velocity Ratings of Wells on page 6. Selection of Thermowells 5

6 Well failures, in most cases, are not due to the effect of pressure and temperature. The calculations necessary to provide adequate strength, under given conditions, are familiar enough to permit proper choice of wall thickness and material. Velocity Ratings of Wells Less familiar, and more dangerous, are the vibrational effects to which wells are subjected. Fluid, flowing by the well, forms a turbulent wake (called the Von Karman Trail) which has a definite frequency based on the diameter of the well and velocity of the fluid. It is important that the well have sufficient stiffness so that the wake frequency will never equal the natural frequency of the well itself. If the natural frequency of the well were to coincide with the wake frequency, the well would vibrate to destruction and break off in the piping. On the following pages, a recommended maximum velocity rating can be found for every standard well length and material cataloged. To reduce the complexity of presenting this information, the ratings given are based on operating temperatures of 1000ºF for wells made of Carbon Steel (C-1018), A.I.S.I. 304 & A.I.S.I Values for brass wells are based on 350ºF operation. Limits for Monel wells are based on 900ºF service. Slightly higher velocity is possible at lower temperatures. Where single values appear in the velocity tables, these may be considered safe for water, steam, air or gas. In the shorter insertion lengths, consideration is given to the velocity pressure effect of water flowing at higher velocities. The values in parenthesis, therefore, represent safe values for water flow while the unbracketted value may be used for steam, air, gas and similar density fluids. It should be pointed out that the values given are extremely conservative, and intended primarily as a guide. Wells are also safe if the resonant frequency is below the wake frequency or if the fluid velocity is constantly fluctuating through the critical velocity point. If the installation is not hampered by the use of a sufficiently stiff well, we recommend the values given not be exceeded. If you have operating conditions requiring special well designs, our Engineering Staff is available to assist you. 6
