Industrial Applications

1. Fastener Protection in Nuclear Reactor Coolant Systems

Nuclear electric power generating plants demand high-purity materials with trace halogen and sulfur levels to prevent stress corrosion cracking in high-temperature environments. LB 8013 is PMUC-approved and contains <=50 ppm chloride and <=100 ppm sulfur, making it ideal for treating bolts, studs, and valves in steam generators and reactor coolant loops.

Problem Solved

Prevents catastrophic stress corrosion cracking (SCC) of critical stainless steel fasteners subjected to operational temperatures up to 1315°C, while enabling non-destructive disassembly for inspections.

2. High-Temperature Flange and Pipe Fitting Lubrication

Refineries and chemical processing plants utilize high-temperature piping systems that transport corrosive fluids. Standard metallic anti-seize compounds can cause galvanic corrosion on stainless steel flanges and fittings. LB 8013 provides a metal-free, high-purity barrier that withstands chemicals and up to 1315°C heat without decomposing.

Problem Solved

Eliminates galling and seizing of threaded joints, fittings, and slip fits exposed to high temperatures and aggressive chemical atmospheres, facilitating uniform clamping pressure (K-factor of 0.18 on stainless steel) and easy maintenance disassembly.

3. Steam Valve Stem and Press Fit Protection in Paper Manufacturing

Paper mills run continuous steam lines and high-heat drying sections where control valves operate under extreme heat and heavy loads. LB 8013's non-curing, calcium oxide/graphite-based formula offers superior lubrication and load-carrying capacity in steam valve stems, press fits, and slip fits.

Problem Solved

Prevents critical valve stems and press-fitted components from seizing or wearing out prematurely under high-temperature steam exposure, ensuring smooth actuation and preventing costly production line shutdowns.
