Materials
Pipe Fitting Materials & Grades
We manufacture pipe fittings in a comprehensive range of materials — from standard carbon steel to exotic high-performance alloys for every piping service condition.
CS
Most Common
Carbon Steel
Standard carbon steel fittings for general piping applications — high strength, weldable and available in the widest size and schedule range at the most competitive pricing.
SS
Corrosion Resistant
Stainless Steel
Stainless steel pipe fittings for corrosive, hygienic and high-temperature service — chemical processing, food & beverage, pharmaceutical and marine piping systems.
AS
High Temperature
Alloy Steel
Chrome-molybdenum alloy fittings for high-temperature and high-pressure service in power generation, refineries and petrochemical plants operating at elevated temperatures.
DS
Offshore Grade
Duplex & Super Duplex
For offshore, subsea and aggressive chemical piping — superior strength and chloride corrosion resistance compared to standard austenitic stainless steels.
NI
Exotic Alloys
Inconel & Hastelloy
Nickel-based superalloy pipe fittings for extreme temperature and corrosion service — gas turbines, chemical reactors and other critical applications beyond standard grade capabilities.
LT
Cryogenic Service
Low Temperature Steel
Fittings for cryogenic and low-temperature piping service — LNG, liquid nitrogen and refrigeration systems operating below -46°C where standard carbon steel becomes brittle.

BW
Butt Weld Elbows — 90° LR, 45° & 180°
ASME B16.9 · Long Radius (1.5D) & Short Radius (1D)
Description
Butt weld elbows change the direction of flow in a pipeline. Long radius (LR) elbows have a centre-to-face dimension of 1.5× the pipe OD — providing lower pressure drop and less turbulence. Short radius (SR) elbows are 1× OD — used where space is restricted. The 45° elbow changes direction at a shallower angle for smooth flow transitions.
Applications
Process piping · Oil & gas flowlines · Steam lines · Chemical plant · Structural & utility piping · All industries requiring directional change
Standards & Specifications
BW
Tees (Equal & Reducing) and Reducers
ASME B16.9 · Equal Tee, Reducing Tee, Concentric & Eccentric Reducer
Description
Tees split or combine flow in a piping system. Equal tees have three ports of the same size; reducing tees have a smaller branch outlet. Concentric reducers connect pipes of different sizes with the same centreline — used in vertical lines. Eccentric reducers are offset — used in horizontal lines to maintain a level bottom (to avoid air pockets or liquid traps).
Applications
Tee: distribution headers · Branch connections. Concentric reducer: vertical process lines. Eccentric reducer: pump suction lines · Horizontal gas lines · Any line requiring a level invert
Standards & Specifications
SW
Forged Socket Weld Fittings
ASME B16.11 · Class 3000 / 6000 / 9000 · ½”–4″
Description
Forged socket weld fittings are used on small-bore high-pressure piping (up to 4″). The pipe inserts into the fitting socket and is secured by a single fillet weld. Stronger and cleaner bore than threaded fittings. Class 3000 for standard service; Class 6000 and 9000 for high-pressure applications. Manufactured from solid forgings for maximum strength.
Applications
Chemical injection lines · Instrument piping · High-pressure hydraulic systems · Small-bore process lines · All high-pressure small-bore applications
Standards & Specifications
THD
Forged Threaded Fittings & Couplings
ASME B16.11 · NPT / BSP Thread · No Welding Required
Description
Forged threaded fittings (NPT or BSP thread) connect pipes without welding — ideal for hazardous areas, non-weldable locations or where frequent disassembly is required. Includes elbows, tees, couplings, unions, bushings, plugs and caps. Available in Class 2000, 3000 and 6000 pressure ratings per ASME B16.11.
Applications
Hazardous area piping · Instrument connections · Temporary piping · Non-weldable locations · Air & water service · Utility piping where welding is impractical
Standards & Thread Types
Sch
Wall Thickness Schedules Explained
Sch 10S · Sch 40 · Sch 80 · Sch 160 · XXS — What Each Means
What is Schedule?
Schedule (Sch) refers to the wall thickness of a pipe fitting relative to its outside diameter. A higher schedule number means a thicker wall and therefore higher pressure rating. Schedule 40 is the most common standard weight for carbon steel. The “S” suffix (e.g. 10S, 40S) is used for stainless steel schedules per ASME B36.19.
Selection Guide
Sch 10S/20: Low-pressure utility · Sch 40 (STD): General purpose · Sch 80 (XS): High-pressure · Sch 120/160: Very high pressure · XXS: Extreme pressure & thick-wall applications
