Standard Platecoil Ordering Guidelines Orders must contain a complete description of the PLATECOIL required. The following illustrates the descrip- tion of a typical order. Charts found on pages 12-14. Obviously, any material that has previously proven satisfactory in a particular application at your plant, would be a safe choice when the PLATECOIL is to be used for the exact same service. Size Selection The amount of surface area required to provide necessary heating or cooling, particularly when Standard Style PLATE- COIL are to be used in open tank applications, can quickly be calculated...

Standard Platecoil Handles Hangers One or two handles (Fig. 3-1) are furnished as standard on PLATECOIL “Quick Change” hangers are designed as a PLATECOIL Styles 90, 70 and 50. Unless specified, they are convenient, economical means of supporting PLATECOIL not furnished on Styles 80 or 60, or on Single Embossed at the proper distance from the tank wall. They are conPLATECOIL. structed of the same material as the PLATECOIL with which they are used. Two standard hanger models are available. No. 5504 is for use with PLATECOIL of 22 inch width, or less. They are fabricated from 14 ga. carbon...

Standard Platecoil Internal Operating Applicable to Style 70, 80 & 90 MULTI-ZONE and 320 head- er and Style 50 & 60 serpentine pass. ASME code pressure ratings are available from the factory upon request. 1. Standard test pressure is 250 psig air under water. For pressures above 250 psig hydrostatic tests are performed. 2. Ratings for carbon steel apply for -20°F to 500°F and are based on a 4 to 1 greater safety factor without corrosion 3. Ratings for stainless steel and Monel apply up to saturated steam temperature for pressures shown with 5 to 1 or greater safety factor without corrosion...

Standard Platecoil Installation of Clamp-On Platecoil 1. Have a full set of drawings on location for the installation. Identify and mark the Platecoil's with their location on the 2. Be sure that the correct mastic type and quantity has been purchased in line with their maximum operating temperature for the Platecoil and the process fluid. You will need 1 gallon for every 13 ft2. 3. Identify Platecoil when they arrive to the drawings. 4. Layout Platecoil on ground in the same configuration as they will be installed. 5. Weld in bottom support lugs to set Platecoil's on while installing (not...

Optional Features PLATECOIL's unique design versatility allows it to be curved and/or rolled to specific radii. Both single and double embossed units can be furnished with either dimension curved. Normal tolerances are: Angle of Coverage O Radius Tolerance When PLATECOIL is clamped to the outside of a tank, using Tranter's standard mounting lugs, the PLATECOIL radius is designed to allow a 1/4" gap at the ends of the PLATECOIL. Tranter PHE, Inc. has developed this method to ensure prop- er fit-up at installation. The PLATECOIL radius is selected using individual PLATECOIL dimensions and the...

Optional Features Mountign Lugs PLATECOIL mounting lugs are used exclusively for mounting purposes. Standard lugs are illustrated in Fig. 8-1 and adaptations and attachment locations are shown in Fig. 8- 2. These lugs are generally used as follows: L-1E - Used on end or side of PLATECOIL for clamping them tightly to tanks or vessels, the usual lug spacing on the side is 30 inches. Generally the PLALECOIL are single embossed and rolled. L-2F - Foot type support for PLALECOIL installed on end. F-2FX - Same as L-2F except a 3 inch leg is added (height can be varied) to provide clearance above...

Custom Platecoil Clamp-On PLATECOIL Application Data Heat Transfer Mastics The thermal resistance of the air gaps between clamp-on PLATECOIL and tank surfaces may be reduced by the use of a heat transfer mastic, applied at the time of installation. This will provide improved performance by increasing the overall coefficients of heat transfer as shown in Fig. 10-1. Average Overall Heat Transfer Rates U = Btu/hr sq ft F By applying the mastic to the tank at the time of installa- tion, its thickness can be generally controlled to fill voids and low spots with less at weld beads or high points....

Platecoil Materials Selection PLATECOIL Material Selection Charts Material selection charts are presented here to assist in determining the most suitable material for various environ- The first chart (Fig. 11-1) is a practical listing of Common Metal Finishing Solution. Many of these involve complex mixtures of chemicals so they are presented separately. The materials shown are generally used for the solutions shown. Some ratings shown in the general material selection chart are the result of laboratory rests conducted by suspending samples of the material in the solution. Therefore, they...
