Product Overview
Our Carbon Steel Concentric Reducer is made from ASTM A234 WPB carbon steel, and it sticks strictly to ASME B16.9 standards.
Key Details
This material's no slouch-tensile strength sits between 415-550MPa, with yield strength at least 240MPa. That means it can handle the pressure in busy industrial setups without breaking a sweat.
The concentric design keeps the pipe centerlines lined up, which cuts down flow resistance by about 35% compared to those off-kilter reducers. It works with pressures from Class 150 up to Class 900, and handles temps from -20°F to 800°F.
Perfect for oil, gas, and chemical pipelines- fussno, just reliable performance.
Each reducer undergoes precise machining with CNC lathes, achieving dimensional tolerances within ±0.01 inches on all critical surfaces. We apply a phosphate coating followed by oiling, which meets SSPC-SP 8 standards and provides up to 12 months of rust protection in dry storage.
Weld preparation includes a 37° bevel angle with a 0.06-inch root face, ensuring proper penetration during welding. Every unit goes through a magnetic particle inspection (MPI) to detect surface cracks, with a 100% pass rate per ASTM E709.
We've got 20 CNC machining centers and 6 automated production lines running here. That lets us make 120,000 units a year, so even big wholesale orders don't get stuck in a backlog.
We keep over 8000 ready-made Carbon Steel Concentric Reducer in stock, covering common sizes like 6x4 inches and 8x6 inches. You can check what's in stock right away, and we can ship most orders within 2 days.
Quality checks? We don't mess around. Every batch gets ultrasonic testing (following ASTM E164) to catch any hidden flaws. We also use a coordinate measuring machine that's accurate to 0.0002 inches to check dimensions.
All that care means our defect rate stays under 0.1%-pretty solid, if you ask us.
1.Order 2000 pieces or more, and you'll get an 8% wholesale discount. Plus, we'll ship for free to major ports in Europe and North America.
2.We stand behind our work with a 5-year warranty. If there's a problem from how we made it or the materials we used, we'll fix it-no questions.
3.And if any reducer doesn't meet those ASME B16.9 standards? We'll replace it free, and cover any reasonable costs that came from the issue. Simple as that.
