What We Supply
Carbon steel flanges, lightweight large-diameter solutions, and custom piping components engineered to international standards for reliable industrial applications.
Carbon Steel Flanges
Full inventory of ASTM A105, A350 LF2, A516, and A694 grades in weld neck, slip-on, blind, threaded, socket weld, and lap joint configurations. ASME B16.5 & B16.47 certified, all pressure classes, complete Material Test Reports with chemical composition, mechanical properties, and heat number traceability. Sizes 1/2" through 144" diameters.
View Details →Lightweight & Large-Diameter Flanges
Class 125LW lightweight flanges and AWWA C207/C228 specifications for water and wastewater systems. Large-diameter designs from 4" through 144" reduce weight while maintaining structural integrity. Ideal for waterworks, irrigation, and low-pressure piping applications. Full compliance with AWWA standards and dimensional accuracy.
View Details →Pipe Fittings & Custom Machining
Comprehensive selection of elbows, tees, reducers, and custom-machined components. CNC precision machining accepts drawings, sketches, or performance specifications. Non-standard bores, special bolt patterns, custom facings, and specialty finishes. Whether standard or engineered-to-order, rapid turnaround with complete documentation.

Slip-On
Fits over pipe; common for non-critical applications.
Threaded
Screws onto pipe; reversible without cutting.
Socket Weld
Compact connection; ideal for small bore applications.
Lap Joint
Slides over stub ends; facilitates equipment removal.
Orifice
Pressure drop measurement; integral or removable plates.
Long Weld Neck
Extended neck for thick-wall pipe or reinforcement.
