Overview	Features	Typical Specifications
Typical Specifications Design The unit shall be provided with an aluminum or stainless steel OSHA splash shield. The units shall be built in accordance with ASME code and when necessary be ASME Code stamped board registered. Frame The frame plate and pressure plate should be carbon steel SA 516 grade 70. The frame and pressure plate shall be of sufficient thickness to meet the ASME design pressure. Stiffeners or support brackets are not allowed. Carbon steel frame components shall be painted with Armstrong “Harvester Red” epoxy paint. Units with four-inch or greater connections shall be unlined or alloy lined studded ports to mate with raised face or flat faced ANSI flanges. Rubber liners are not allowed. Units with two-inch or smaller connections shall have carbon steel female tapped NPT or male NPT connections if an alloy material is required. Units with two and half or three-inch connections shall be either studded ports or NPT as describe above. The frame design shall allow the thermal plates to be supported by the carry bar, top bar. The guide bar, bottom bar, shall only help properly align the plates. A roller assembly from the carry bar shall support the pressure plate for units taller than 50". Tightening bolts shall be zinc plated carbon steel SA193 B7. Plates Plates shall be constructed of 316 L Stainless Steel. Plates shall be pressed in a one step stamping process. Plates shall use an integral rolled edge hanging system to provide a rigid hanger device between the plate and carry bar and guide bar. Welded on hanging brackets or stiffeners are not acceptable. Plates shall be permanently marked to indicate plate material and thickness. Gaskets The gaskets shall be a one-piece construction with a double gasket barrier at the port region. The area isolated by the double gasket shall be vented to the atmosphere, so that a gasket failure is detected by leakage to the exterior prior to any possible cross contamination. Gaskets are to be “mechanically fixed”. Glued gaskets are not acceptable. The gaskets are to be made of NBR. Selection, Certification and Testing The manufacturer shall hydro-test the unit to 1.3 times the design pressure as directed by ASME Code.
