METALLIC BUTTWELD FITTINGS
CARBON STEEL BUTTWELD FITTINGS
Carbon steel buttweld fittings are extensively used in oil & gas, firefighting, and industrial piping systems. Supplied in ½”–36” NB, ANSI B16.9, schedules 10S–XXS, they are manufactured to ASTM A234 WPB / WPB-W for strength, weldability, and cost efficiency.
SUPERDUPLEX BUTTWELD FITTINGS
Super duplex buttweld fittings are engineered for extreme corrosion and high-pressure applications. Supplied in ½”–36” NB, to ANSI B16.9 / ASTM A815, grades UNS S32750 and S32760 provide superior resistance to pitting and crevice corrosion in offshore and desalination-related systems.
STAINLESS STEEL BUTTWELD FITTINGS
Stainless steel buttweld fittings are widely used in process, utility, and corrosive service piping across Saudi industrial projects. Supplied in ½”–36” NB, to ANSI B16.9 / MSS-SP-43, with schedules 10S–XXS, they conform to ASTM A403 WP. Common grades include 304/304L, 316/316L/316Ti, 309, 310, 317, 321, 347, and 904L, selected for corrosion resistance and long-term reliability.
LOW TEMP BUTTWELD FITTINGS
LTCS buttweld fittings are designed for low-temperature and cryogenic services. Available in ½”–36” NB, ANSI B16.9, they comply with ASTM A420 WPL6, maintaining impact toughness in gas and temperature-critical piping systems.
DUPLEX BUTTWELD FITTINGS
Duplex buttweld fittings are specified for higher strength and chloride resistance in chemical and offshore environments. Available in ½”–36” NB, ANSI B16.9, ASTM A815, grades UNS S31803 and S32205 offer improved resistance to stress corrosion cracking in demanding services.
ALLOY STEEL BUTTWELD FITTINGS
Alloy steel buttweld fittings are used in high-temperature and high-pressure systems such as steam and thermal lines. Supplied in ½”–36” NB, ANSI B16.9, to ASTM A234 WP5, WP9, WP11, WP12, WP22, and WP91, they offer excellent creep and strength retention.
Buttweld fittings are essential components in high-pressure, high-temperature, and corrosion-critical piping systems used across oil & gas, petrochemical, power, water, and desalination projects in Saudi Arabia. Manufactured in carbon steel, alloy steel, stainless steel, duplex, super duplex, copper nickel, Monel, Inconel, Hastelloy, and nickel alloys, buttweld fittings provide excellent flow characteristics, structural integrity, and weld strength. Supplied in ½” to 36” NB, with schedules ranging from 10S to XXS, and produced in accordance with ANSI B16.9, MSS-SP-43, and relevant ASTM standards, these fittings are widely specified for process, transmission, and utility pipelines where durability, compliance, and long service life are mandatory.
COPPER NICKEL BUTTWELD FITTINGS
Copper nickel buttweld fittings are used in seawater, brine, and cooling systems due to superior resistance to corrosion and biofouling. Supplied in ½”–36” NB, ANSI B16.9, common grades include C70600 (90/10), C71500 (70/30), and C71640.
NICKEL BUTTWELD FITTINGS
Nickel buttweld fittings are used in chemical and caustic service piping where resistance to alkalis and corrosive media is required. Supplied in ½”–36” NB, ANSI B16.9, materials include UNS N02200 and N02201.
MONEL BUTTWELD FITTINGS
Monel buttweld fittings are selected for marine and highly corrosive environments where strength and chemical resistance are critical. Available in ½”–36” NB, ANSI B16.9, materials include UNS N04400, N05500, and Alloy 20.
INCONEL BUTTWELD FITTINGS
Inconel buttweld fittings are specified for extreme temperature, pressure, and oxidation environments. Available in ½”–36” NB, ANSI B16.9, alloys include UNS N06600, N06601, N06625, N08800, N08810, and N08825, commonly used in high-temperature process systems.
HASTELLOY BUTTWELD FITTINGS
Hastelloy buttweld fittings are engineered for extreme chemical corrosion and high-temperature service. Supplied in ½”–36” NB, ANSI B16.9, grades such as UNS N10276, N06022, N06625, and N06455 are used in critical process piping.
TYPES OF BUTTWELD FITTINGS
Common buttweld fitting types include elbows (45°, 90°, 180°), reducers (concentric and eccentric), tees (equal and reducing), caps, stub ends, laterals, bends, and end clamps, manufactured for smooth flow and full-penetration welding.
