At Dhanlaxmi Stainless, we manufacture and supply a comprehensive range of Threaded Pipe Fittings engineered for high strength, dimensional precision, and leak-proof connections in low to medium pressure applications. Our threaded fittings are produced using premium materials such as Stainless Steel (ASTM A182 F304, 304L, 304H, 316, 316L, 317, 317L, 321, 310, 347, 904L), Carbon Steel (ASTM A105, A350 LF2, A694 F42 to F70), and Alloy Steel (ASTM A182 F1, F5, F9, F11, F22, F91).
We also offer corrosion-resistant options in Duplex and Super Duplex Steels (UNS S31803, S32750, S32760) and High Nickel Alloys including Inconel (600, 625, 718), Incoloy (800, 825, Alloy 20), Monel (400, K500), and Hastelloy (C22, C276) to serve aggressive service environments.
Our Threaded Fittings are available in sizes from 1/8" to 4" NPS and conform to international standards such as ASME B16.11 and BS 3799. We supply fittings in Class 2000, 3000, and 6000 pressure ratings, ensuring compatibility with various process and utility piping systems.
The product line includes Threaded Elbows (90° & 45°), Equal & Reducing Tees, Full/Half/Reducing Couplings, Unions, Caps, Plugs, Bushings, Reducers, Crosses, Nipples, and Adapters. These fittings are widely utilized across Oil & Gas, Petrochemical, Pharmaceutical, Power Generation, Water Treatment, and Fire Protection systems for their easy installation, reusability, and low-maintenance performance. We provide full traceability and can offer MTCs, NACE compliance, and Third-Party Inspections on request.

Threaded Elbows are used to change the direction of flow in threaded piping systems without welding. We offer 90°, 45°, and Street Elbows for applications requiring quick and compact directional transitions. These fittings are ideal for low to medium pressure systems where frequent disassembly or maintenance is expected.
Threaded Tees are T-shaped fittings used to combine or split fluid flow in threaded piping systems. Equal Tees have all three outlets of the same size, while Reducing Tees connect pipes of different diameters. These fittings are widely used in low to moderate pressure applications where welding is not feasible.
Threaded Couplings are cylindrical fittings used to join two threaded pipes in a straight line. We offer Full Couplings for connecting two pipes of the same size, Half Couplings for welding one end, and Reducing Couplings for joining pipes of different diameters. These are ideal for small bore piping systems where welding is not preferred.
Threaded Unions are essential fittings designed for easy assembly and disassembly of piping systems without requiring any rotation of the pipes. These fittings consist of three parts — a male end, a female end, and a nut — ensuring a secure and reusable connection. Ideal for maintenance-intensive systems where pipe connections may need to be accessed frequently.
Threaded Caps are used to seal the ends of pipes in threaded piping systems, preventing leakage, contamination, and entry of foreign materials. These caps are easy to install and remove, making them ideal for temporary or permanent pipe closures in various applications.
Threaded Cross Fittings feature four openings at right angles, allowing fluid or gas to flow through three branches from a main pipeline. Available in both Equal Cross and Reducing Cross variants, these fittings are ideal for compact piping networks requiring multiple connections in a confined space.
Threaded Nipples are short lengths of pipe with male threads on both ends, used to connect two other fittings or piping sections. Available in various lengths and diameters, these are essential for close-coupling applications, system extensions, or repairs. We supply both Swage Nipples and Pipe Nipples for a wide range of pressure ratings.
Threaded Adapters are used to convert one type of thread connection to another or to connect threaded components with different thread genders. Male Adapters feature external threads, while Female Adapters have internal threads, allowing flexible integration into piping systems. These adapters are widely used for quick, easy installation without welding.
Threaded fittings are widely used in low to medium pressure applications across industries that require easy assembly, disassembly, and leak-resistant joints without welding.
Used for utility piping, instrumentation lines, and non-critical fluid transport in refineries, rigs, and processing facilities.
Ideal for piping systems in corrosive chemical environments where quick disconnection or component replacement is required.
Used in compact piping layouts, machine equipment, and control systems in manufacturing and general engineering plants.
Essential in sprinkler piping and emergency systems where fast installation and reliable connections are crucial.
Widely used in domestic, commercial, and industrial plumbing for their simplicity, reusability, and leak resistance.
Suitable for clean and sanitary piping systems requiring easy disconnection for regular cleaning and maintenance.
