We deliver industry-leading solutions for connecting critical service piping and vessel systems.
GRAYLOC® CLAMP CONNECTORS
DESCRIPTION
The Grayloc® Connector has been a fieldproven and reliable mechanical connector for over 50 years. This connector features a metal-to-metal bore seal that is recognized as the standard for critical service piping and vessel connections. Grayloc® connectors save weight, space, and fabrication time. Long after installation, ongoing advantages include lowered maintenance costs, reduced inventories, and increased performance.
DESIGN TECHNOLOGY
>> Grayloc® metal-to-metal seal
>> Self-energized and pressure-enhanced seal
>> Two-piece, four-bolt clamp design
>> Primary load-retaining member is the clamp, not the bolting
>> Significant space- and weight-saving design
>> Low makeup bolt torque
>> Visual indication of proper assembly
>> Reusable seal rings
BENEFITS
>> Eliminates fugitive emissions with zero-leakage seal (10-6 atm cc/s helium)
>> Reduces installation time with only four bolts and 360° clamp rotation
>> Simplifies fabrication (no bolt holes to align)
>> Lowers maintenance costs
>> Minimizes spare parts inventory
>> Enables design of lightweight and compact piping systems, using integral fitting configurations
>> Grayloc hub profiles can be integrated into third-party (OEM) products

GRAYLOC® COMPACT FLANGES
DESCRIPTION
Grayloc® compact flanges (GCFs) incorporate our proven metal-to-metal technology into a bolted flange design. Including the Grayloc seal ring in a compact flange design provides a solution with significant space and weight savings that outperforms conventional flanges.
DESIGN TECHNOLOGY
>> Grayloc® metal-to-metal seal
>> Self-energized and pressure-enhanced seal
>> Space and weight are less when compared to conventional flanges
>> Optimized bolting configurations
>> Engineered to industry standard design codes, including ASME and API
>> Visual indication of proper assembly
>> Reusable seal rings
BENEFITS
>> Eliminates fugitive emissions with zero leakage seal (10-6 atm cc/s helium)
>> Enables significant space and weight savings
>> Reduces installation time with smaller and fewer bolts
>> Lowers maintenance cost
>> Minimizes spare parts inventory
>> Eliminates mismatches common in male and female designs with standard seal interfaces
>> Enables design of lightweight and compact piping systems using integral fitting configurations
>> Enables integrating Grayloc hub profiles into third-party (OEM) products
