What is the difference between SS 304 and SS 316L pressure vessels?

SS 304 is a general-purpose stainless steel suitable for food, water, and mild chemical applications. SS 316L contains molybdenum which provides superior resistance to chlorides, acids, and corrosive chemicals u2014 making it the standard choice for pharmaceutical, chemical, and marine applications.

What does IBR certification mean for pressure vessels?

IBR (Indian Boiler Regulations) certification is mandatory for pressure vessels used in steam generation or that operate above specific pressure-temperature thresholds in India. IBR vessels undergo third-party inspection and hydraulic pressure testing before installation.

What is the typical lead time for a custom SS pressure vessel in India?

Lead times for custom stainless steel pressure vessels in India typically range from 4u201312 weeks depending on capacity, complexity, material grade, and whether third-party inspection (IBR, ASME) is required.

Can FRP pressure vessels handle acids?

Yes. FRP pressure vessels are designed for highly corrosive acids, alkalis, and chemicals where stainless steel would be attacked. They are widely used in pickling, effluent treatment, and chemical storage applications.

What is a jacketed reaction vessel used for?

A jacketed reaction vessel has a double-wall construction that allows a heating or cooling medium (steam, hot oil, chilled water) to circulate around the vessel, enabling precise temperature control during chemical reactions, blending, or fermentation.
