ASME Pressure Vessels EEServ

EEServ has the capabilities to design and manufacture all types of pressure vessels to ASME Section XIII standards. These include exotic alloys -- such as Hastalloy C-276/C-22, Inconel, and duplex stainless steels -as well as more conventional 304 and 316L stainless and carbon steel. ATI 2205Duplex Stainless Steel (UNS S31803 and S32205) GENERAL PROPERTIES ATI 2205alloy (UNS S31803 and/or S32205) is a nitrogen-enhanced duplex stainless steel alloy. The nitrogen serves to significantly improve the corrosion resistance of the alloy; especially in the welded condition.

Also in 1994 we fabricated four duplex stainless steel jacketed tanks. These tanks were polished on the inside and utilized a duplex half pipe on the outside. Figure 7 shows the interior surface of the vessel. The higher hardness of duplex stainless steels as compared to austenitic stainless gives a better nish. They were a replacement for Stainless Steel Storage Vessels Duplex 2205 Stainless SteelThe Wilson Hot Water cylinders are manufactured high grade Duplex 2205 stainless steel, are cased in colorbond steel and insulated with foam. Stainless Steel Storage Vessels Features:Watermark approved; High grade polyurethane foam insulation; Duplex 2205 stainless Steel; 20 year warranty; These vessels are fitted as standard with 50 mm fittings however other sizes/styles can be offered e.g. Table E Standard Specification for Stainless Steel Forgings This specification covers ferritic/austenitic (duplex) stainless steel forgings for boilers, pressure vessels, and associated equipment. The steels shall be manufactured using melting and forging processes. Forgings may be machined before solution annealing. The


unfired pressure vessels EN 13445:2002 contains an innovative design procedure based on Finite Element Analysis (FEA), called Design by Analysis-Direct Route (DBA-DR). According to the code duplex steels should be designed as they belong to ferritic stainless steels. Such statement What is Duplex and Super Duplex Stainless Steel?Aug 16, 2017 · This makes duplex stainless steel a popular choice for structural applications and pressure vessels. As with all stainless steels, duplex stainless steels benefit from this characteristic. The level of corrosion resistance depends on the grade of duplex stainless steel, and these levels are similar to the range for austenitic stainless steels.DUPLEX Stainless SteelDuplex Stainless Steels have roughly twice the yield strength of their counterpart austenitic grades. This allows equipment designers to use thinner gauge material for vessel construction!
