Cleaning of Shandong heat exchanger, the inside thread of ARI thread is made of alloy alloy double head bolt with alloy inner thread. Armstrong Phe series uses solid stainless steel plate  standard structure  as the main medium of heat transfer. Smo 254 - a kind of corrosion resistant steel alloy and titanium can be supplied as required. Each plate has an optimized corrugated design mark. This series of plates creates an alternate independent channel for process and working fluids. Two medium circuits are configured to generate a counter current of * * to allow the heat exchanger to operate at very low temperatures. This feature is further enhanced by using the Armstrong X-Series board. Each liquid flows through its various channels ᚜ the cleaning corrugated flow from the herringbone Shandong heat exchanger flows through the  corrugated mode ᚜ this increases the liquid turbulence ᚜ and increases the heat transferred through the plate. Heat is transferred from one medium to another. Armstrong Phe series uses gasket seals to separate the operating side from the process side. The neck free flange and stud on the 14376251 fixed cover plate can share the force from the pipe. 2. The gasket in the interface area is double exhaust type to eliminate the cross contamination of liquid. The gasket is cleaned and installed on the plate by mechanical method, and there is no adhesive. The gasket can only be installed on the plate in one direction, eliminating assembly errors and avoiding wasting time during maintenance. The gasket is visible from the outside of the unit, so it can ensure the correct installation. 3. The fastening bolts are designed to perform all fastening work from the fixed end. The nuts at the movable end are in the locked state. The bolts have corrosion resistant coating. This makes the maintenance of heat exchanger more quickly and conveniently. 4 the iron strip used to support the heat transfer plate is treated with corrosion protection and is easy to maintain. 5. The design of heavy pressure retaining head conforms to ped and ASME standards and adopts the stress calculation data of * * to ensure long-term operation. 6 heat transfer plate shall be marked with H or W mode as required by application. 7 the aluminum protective covers the top and sides of the panel set. Design features. Typical specification 1.1 is installed with plate heat exchanger manufactured and designed by Armstrong and assembled, inspected and tested to meet the planned heat and hydraulic requirements. 1.2 the heat exchanger design shall comply with applicable regulations: ped, ASME, TSSA. 1.3 each heat exchanger plate shall be pressed one step from a single 304SS, 316SS or titanium sheet with 2B surface. The thickness of the plate shall be determined by the manufacturer to meet the design pressure and temperature requirements. The plate shall be provided with herringbone corrugated and shall be of a depth, space and thickness capable of withstanding the full pressure difference of the plate by 1.3 to 1.5 times greater than the design pressure without deformation or failure. 1.4 each plate shall have a gasket made of nitrile, EPM or other materials. These materials shall be compatible with all working fluids and shall be able to work continuously at design temperature. The gasket section should be tent shaped to achieve better sealing effect and reduce the compression stress. 1.5 the gasket shall be provided with a vent groove in the unused area of the plate to prevent liquid mixing and prevent any leakage that is visible from outside the heat exchanger caused by the gasket. The washer grooves in each plate shall have a proper depth of ᚜ to fully accommodate the gasket profile. 1.6 unless otherwise approved, the gasket shall be mechanically mounted to a specific U-tube at the outer edge of the plate using a non adhesive clamp type. The gasket clips should be visible from the outside to verify that they are installed correctly. Do not use rubber free gasket that is outside the flange of the winding plate and may be damaged. For some applications, adhesive gasket is acceptable. 1.7 the design and construction of pressure retaining frame shall ensure reliable operation and easy maintenance during the service life of heat exchanger. The frame shall be bolted together for assembly and field installation. The cover of the device shall be of sufficient uniform thickness and bolted to withstand all loads. Cleaning, furnishing and painting of cover and all other carbon steel parts of Shandong heat exchanger cleaning 1.8 shall comply with Armstrong standard. For heat exchangers 1270 mm (50 ") or higher, movable covers with rolling components shall be provided so that they can be easily moved when assembling and checking the plates. The connection device of 1.9 * * is all 4 connections on the fixed front cover. Flow units shall be vertical. Oblique flow mode is not accepted. Stud DIN or BSP type connections shall be part of the cover to eliminate nozzle pipe load and leakage in the connection area. 2.0 the stress bars and fastening bolts of the plate shall be stainless steel or galvanized carbon steel to prevent rust and facilitate maintenance. Surfaces not to be painted. 2.1 the frame and the stress bars shall be designed to allow maintenance space when the plate is expanded by 20% of the capacity. 2.2 all devices shall be equipped with aluminum protective covers to protect the human body and prevent the plate and gasket from being affected by the elements. 2.3 if ARI certification is required, the suppliers and equipment of liquid-liquid heat exchanger * * are already in www.ahridirectory.org Listed on. Other Armstrong solutions IVS sensorless pumps are designed to meet the needs of energy-saving pumping systems in today's buildings. The traditional pump system uses constant speed pump Shandong heat exchanger to clean and control the flow with original throttle valve. The life cycle analysis shows that the input cost of constant speed pump is usually only 5% of its life cycle cost.
