We specialize in high-precision, heavy-duty forged steel flanges, supplying globally certified piping components across the oil, gas, petrochemical, and power generation infrastructure sectors. Our integrated production mill seamlessly executes high-capacity runs across carbon steel, stainless steel, duplex, and exotic alloys, fully complying with ASME/ANSI, EN, DIN, and JIS standards.
The 304 stainless steel weld neck flange is a pipe connection component for high-pressure pipeline systems.
The Black Sch40 Carbon Steel Seamless Tee is for pipeline branching systems in medium and high-pressure environments.
The DN100 (4-inch) carbon steel slip-on flange is a high-quality, high-strength forged flange specifically designed for DN100 pipe connections.
Our DIN standard carbon steel elbows are primarily manufactured through hot-pushing and forging processes, treated with rust-preventative black paint, and extensively used in oil, gas, chemical, and construction pipeline systems.
DN100 Carbon Steel Forged Plate Flange is used in low-to-medium pressure piping systems.
SCH40 Carbon Steel Pipe Cap is a butt-weld pipe fitting to seal the end of pipeline systems in medium to high-pressure applications.
CANGZHOU HANGXIN FLANGE CO., LIMITED manufactures high-quality 8 Holes DIN 2527 PN10 Blind Steel Flanges for industrial piping systems requiring secure pipeline termination and pressure sealing.
The Carbon Steel Sch40 Pipe Elbow is a key pipe fitting used to change flow direction in medium to high-pressure piping systems.
A105 carbon steel blind flanges are solid forged components used for closing the end of piping systems, pressure vessels, or valve openings.
PN10 DIN 2576 plate flange is a slip-on welding flange for low-pressure piping systems up to 10 bar.
The DN80 (3-inch) stainless steel flange is an industrial piping connection component conforming to international standards such as ASME, EN, and JIS, used to achieve bolt-sealed connections between pipes, valves, and pressure equipment.
Carbon steel pipe fittings are used for the connection, turning, and branching of pipeline systems.
We manufacture a complete range of steel flanges to meet different pressure, temperature, and installation requirements.

We operate a vertically integrated, tier-one production workshop designed to guarantee uniform grain refinement and eliminate subsurface macro-defects across varying metallurgies:
Massive Forging Fleet: Powered by 1,600-ton to 4,500-ton hydraulic forging presses and radial-axial ring rolling machines capable of structuring compact grain paths for large-diameter components up to 102 inches.
Metallurgical Heat Treatment: Programmable gas furnaces executing specialized solution annealing( 1040℃–1150℃ + fast water quench) for stainless grades, and computer-controlled normalizing/tempering for low-temperature carbon steels.
Tolerances Within ±0.1mm: A comprehensive workshop setup of CNC vertical lathes and multi-spindle drilling rigs ensuring absolute indexing, flawless pitch circle diameter (PCD) alignment, and zero-leakage gasket seating.
Material selection plays a critical role in flange performance, service life, and project safety. Our manufacturing range covers a wide variety of steel grades for different operating conditions.

Quality Assurance & Inspection
Spectroscopy-Driven Verification
100% incoming steel billets undergo Optical Emission Spectrometer (OES) or handheld XRF/PMI analysis before cutting to eliminate cross-contamination between carbon and alloy batches.
Permanent Heat Number Tracking
Every flange is deeply stamped along its outer rim with the manufacturer logo, material grade, pressure rating, size, standard, and a unique Melt Shop Identifier (Heat Number) directly mirrored on the final MTC.
Full-Scale Destructive & NDT Testing
Equipped for in-house tensile checking, low-temperature Charpy V-notch impact validation, Ultrasonic Testing (UT), and Magnetic Particle Inspection (MPI).
Our steel flanges are trusted by customers across a wide range of industries.
