The best reactor vessel suppliers in China invest heavily on R&D in order to provide premium yet inexpensive products. Reactor vessels are inspected using customized procedures adhering to the most relevant international standards available.
Some of the international standards and national regulations InTouch utilizes in developing inspection protocols include:
Pressure Vessel Standards
Reactor vessels are susceptible to excessive pressure build-up. Complying with pressure vessel standards is essential in ensuring the safety of people working around them.
- ASME BPV (Boiler and Pressure Vessel) Code VIII is composed of three detailed sections pertaining to the design, manufacture, testing, inspection, and acceptance of pressure vessels.
- GB 150-1998 is the Chinese standard which deals with reactors designed to contain pressure ratings of up to 35mPa.
- ISO 16528 provides the requirements for pressure vessels formulated by the International Organization for Standardization.
- EC PED or the European Commission Pressure Equipment Directive provides the regulatory requirements imposed on pressure vessels to be used in European Union territories.
Stainless Steel Standards
Stainless steel is the preferred material in manufacturing reactor vessels primarily because of its high corrosion resistance.
- ASTM G123-00 provides the test method for determining the cracking property of nickel-containing stainless steels when exposed to boiling acidified sodium chloride, a compound commonly used in meat processing.
- ASTM G48-11 covers the test procedures in evaluating the corrosion resistance of stainless steel to ferric chloride solution, a fairly strong solution used in water treatment facilities.
- ASTM G35-98 deals with identifying the corrosion cracking susceptibility of stainless steels to Polytionic Acids commonly found in sulfur containing products.
- ASTM A1010/A1010M-01 covers the requirements for martensitic stainless steel plates, strips, and sheets intended for fabricating reactor vessels for high pressure applications.
- ASTM A1049/A1049M-10 provides the requirements for forged ferritic/austenitic stainless steel intended for high pressure applications.
- ASTM A240/A240M-03 deals with chromium-nickel and chromium stainless steel sheets, plates, and strips intended for fabricating pressure and reactor vessels.
- ASME BPVC IIA provides the requirements for ferrous materials intended for the production of reactor vessels intended for high pressure purposes.
- ASME BPVC IIB covers the specifications for non-ferrous metals for the fabrication of reactor vessels.
Borosilicate Glass Standards
Borosilicate glass is the ideal material in manufacturing small laboratory-type reaction vessels. These types of reactors are highly-resistant to any form of corrosion, very easy to clean, and ideal for conducting series of small chemical reaction tests.
- DIN 12492:1998 is the German standard which provides the requirements for vacuum jacket thermal insulated reaction vessels fabricated from borosilicate glass.
- ASTM C743-87 covers the test method for detecting discontinuities, which are hard to distinguish through conventional visual inspection procedures, in glass-coated reactor vessels
Pressure Gauge Standards
Pressure and temperature are the critical parameters needed to be constantly and correctly monitored while the reactor vessel is at operation.
- ASME B40.200 covers the requirements and recommendations for choosing, constructing, and installing thermometers on equipment such as reactor vessels.
- ASME B40.100 provides specifications for pressure gauges and gauge attachments.
