Fittings

Comprehensive range of fittings for seamless connectivity
Flanged Pipe System

Flanged Pipe System

Flange pipe systems are crucial in various industrial applications, offering versatile and secure connections for fluid and gas transport. These flanged components are designed to be bolted together, creating leak-tight seals suitable for high-pressure and high-temperature applications. The systems can be customized with various materials, sizes, and pressure ratings to meet specific industrial needs in sectors such as oil and gas, chemical processing, and water treatment.

Carbon Steel Seamless Butt-Weld Fittings

Carbon Steel Seamless Butt-Weld Fittings

Carbon Steel Seamless Butt-Weld Fittings are steel butt-welded pipe fittings used for moderate and high temperature service including pressure piping and petrochemical.

Carbon Steel Forged Fittings

Carbon Steel Forged Fittings

Carbon Steel Forged Fittings are forged carbon steel fittings for moderate and high temperature service including pressure piping, petrochemical.

Pipe Branch Connections

Branch Connection

Our stock program includes weldolet, nipolet, weldoflange, nipoflange from 1/2” to 4” in various material grades. The design is in accordance with MSS-SP-97 and/or Bonney Forge, or tailor-made to the application. All branch connections can be verified by mathematical and/or finite analysis in accordance with ASME 31.3 / 31.8 / EN requirements.

Flanges

Reliable flanges for secure pipeline connections
Flanges

Carbon Steel Forged Flanges

Carbon Steel Forged Flanges are primarily used in petrochemical-, pressure systems or pipe joining systems. The pressure rating is determined by the table or drilling, i.e. ASA150, ASA300 or ASA600. Available Carbon Steel Forged Flanges include blind/blank, screwed/threaded, slip on/weld on, socket weld or weld neck.

Flanges

Threaded and Welded Wrought Steel Flanges

These flanges, also referred to as screwed flanges, feature internal threading within the flange bore. This design allows for a secure fit with the corresponding external thread of a pipe. While this connection method offers quick and easy installation, it’s not recommended for high-pressure or high-temperature environments. Threaded and welded wrought steel flanges are primarily utilized in air and water service applications, where their simplicity and efficiency are most beneficial.
