A320 L7 & L7M Stud Bolts with A194 4, 7 & 7M Nuts for Low Temperature

Description

High-strength A320 L7 and L7M stud bolts paired with A194 nuts, impact-tested for cryogenic service down to -101°C and -73°C, compliant with SAES-L-109.

Product Description

Engineered for critical low-temperature applications, these A320 L7 and L7M stud bolts provide the necessary ductility and fracture resistance required in cryogenic environments. Supplied with compatible A194 Grade 4, 7, and 7M hex nuts, this fastening system ensures a secure, leak-free connection for flanged joints operating under extreme cold conditions.

Key Features

Low-Temperature Performance: Impact-tested to maintain toughness at -101°C for L7 studs and -73°C for L7M studs, preventing brittle failure.
Compliance: Manufactured and tested in strict accordance with Saudi Aramco SAES-L-109 standards for bolted flange joints.
Material Integrity: A320 L7/L7M steel offers high yield strength combined with the necessary impact energy for cryogenic service.
Complete Kit: Includes matching A194 nuts to ensure optimal thread engagement and load distribution.

Applications

Ideal for refineries, petrochemical plants, LNG facilities, and offshore platforms where hydrocarbon processing occurs at sub-zero temperatures. These studs are essential for maintaining the integrity of pressure-containing equipment in cold climates or cryogenic processes.
