Stainless Steel Air Preparation

Marine (saline), oil & gas, chemical and harsh industrial environments — wherever the system sits in a corrosive setting (steel mills, gas production, offshore platforms). The AISI 316 build is corrosion-resistant and the metallic parts meet NACE MR-01-75.

The NACE (National Association of Corrosion Engineers) MR-01-75 standard defines material requirements for resistance to sulphide stress corrosion cracking (caused by hydrogen sulphide-bearing gas). It's mandatory for oil and gas production systems — the metallic parts of the Norgren stainless-steel air-prep range meet it (the stainless-steel items themselves are not strictly to MR-01-75).

Lloyd's Register is the independent maritime and offshore certification body. R22's 'Lloyd's Register Type Approved' status means the product meets the requirements for pressure regulators used on marine and offshore platforms (material durability, corrosion resistance, safety). Mandatory for offshore oil and gas rigs and shipping systems.

Typical full chain (in series): (1) F22 filter for coarse filtration after the compressor — removes condensate, dust. (2) B05 or B52G filter-regulator — second-stage filtration + pressure regulation. (3) R05 or R22 regulator — if finer regulation is needed for precision-control applications. (4) L22 lubricator — only if downstream components require oil-mist lubrication (modern oil-free components don't).

The AISI 316 stainless-steel build resists corrosion from aggressive cleaning agents (NaOH, HCl, peroxides) and industrial wash-down. Note: the Norgren datasheets position this range for marine, oil & gas and chemical environments — they do not certify it specifically for food/pharma CIP/SIP processes; confirm hygienic-process suitability against the specific datasheet.
