Fittings
Comprehensive range of fittings for seamless connectivity

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.
- Use: For conveyance of liquids & gasses
- Material: SAE 1008, CQ
- Sizes available: 50 – 1000NB
- Information: Various pressure ratings depending on flange table

Flanges
Reliable flanges for secure pipeline connections

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.
- Code: FLF_A105
- Use: Pipe joining system. Pressure rating determined by the table or drilling
- Material: ASTM A105
- Face Finish: Raised or flat face
- Type: Weld on with hub or slip on, blind or blank, screwed, weld neck, socket weld
- Specification: ANSI B16.5
- Sizes available: Various

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.
- Code: FLP_304L, FLP_316L
- Use: Pipe joining system. Pressure rating determined by the table or drilling
- Material: ASTM A182 stainless steel both Grade 304L and 316L
- Face Finish: Raised or flat face
- Specification: BS10, SANS 1123
- Sizes available: Various

Flanges specifications
