Comprehensive stock of Buttweld Flexolet fittings in Inconel 600, 625, and Incoloy 800, 825 grades are readily available for fast delivery. These materials are ideal for high-temperature, high-pressure applications and resist oxidizing and reducing environments. The Flexolet design ensures smooth flow transitions and leak-proof branch connections in process piping. Fittings are manufactured following ASTM/ASME SB564, SB160, and other relevant standards. Products are available in all common schedules such as Sch 10, 40, 80, and XXS with pressure ratings of 1500#, 3000#, and 6000#. Custom machining, NPT threading, and beveled ends can be provided on request.
Buttweld Flexolet fittings made from stainless steel 304L, 316L, 321, 347, and 904L are supplied for diverse industries including water treatment, food processing, and pharmaceuticals. These outlets offer excellent corrosion resistance, weldability, and long service life. Fittings are supplied in socket weld, threaded, and butt weld types, supporting a variety of piping configurations. All products are compliant with ASTM A182 and ASME standards and are supplied with test certificates and inspection reports. Available in all sizes from 1/8” to 24”, we also offer fittings as per client-specific dimensions and schedules.
Duplex (S31803) and Super Duplex (S32750/S32760) Buttweld Flexolets provide high strength, excellent corrosion resistance, and cost-effectiveness in aggressive environments such as desalination, offshore, and marine sectors. These fittings resist chloride stress corrosion cracking and pitting, making them ideal for critical piping networks. They are available in various types including welding outlet, socket outlet, threaded outlet, and sweep outlet. All products are manufactured in line with ASTM A182 and MSS SP-97 and offered in schedules Sch 10s to Sch XXS. Flexolets are precision-machined and hydro-tested to ensure leak-proof installation.
Monel 400 and Cupro Nickel 90/10, 70/30 Buttweld Flexolets are widely used in marine, oil & gas, and heat exchanger industries due to their excellent resistance to saltwater and acidic environments. These branch outlet fittings provide reliable performance in corrosive atmospheres. Available in threaded, socket weld, and butt weld types, they conform to ASTM B366, B122, and relevant international norms. Flexolets are manufactured with smooth bore design to reduce turbulence and pressure drop in the piping system. We ensure fast delivery, high-quality finishing, and custom sizes as per project specifications.
