Suction Line Accumulator Meters Both The Liquid Refrigerant

Product Description

Product Description

Product Description:

This cryogenic suction line accumulator is engineered for ultra-low-temperature refrigeration systems operating at -60°C to -100°C (-76°F to -148°F), including LNG vaporization cold recovery, cascade freezer tunnels, and biomedical storage. The shell is fabricated from 9% nickel steel (ASTM A553) or 304L stainless steel with Charpy V-notch impact testing at -196°C to guarantee ductility. Internal components feature a low-pressure-drop U-tube with a specialized oil return orifice (0.020"–0.050") fabricated from invar alloy to minimize thermal contraction mismatch. All gaskets are PTFE or multi-layer metal (spiral wound) for leak-tight sealing at cryogenic temperatures. Connections are orbital-weld-ready or flanged (ANSI 300#/600#) with extended neck for insulation. Designed for pressures up to 600 PSIG with full vacuum rating.

Key Features & Selling Points:

(1) Cryogenic-grade materials: 9% nickel steel (A553) or 304L SS with certified Charpy impact test at -196°C guarantees no brittle fracture at operating temperatures down to -100°C

(2) Invar alloy oil return orifice (36% nickel-iron) maintains dimensional stability across a 200°C temperature swing, preventing oil return blockage due to differential thermal contraction

(3) Multi-layer metal spiral wound gaskets (graphite-filled, 304L windings) provide zero-leak sealing under repeated thermal cycling from ambient to cryogenic temperatures

(4) Extended-neck flanges (ANSI 300#/600#) allow insulation thickness up to 6 inches without interfering with bolting, reducing heat ingress by 50%

(5) Internal low-profile U-tube design minimizes liquid refrigerant hold-up at cryogenic temperatures, reducing refrigerant charge by 20% compared to standard accumulators

(6) Optional cold-box mounting bracket with thermal break pads prevents cold bridging to the structural frame, minimizing frost formation
