Manufacturing Excellence & Quality Validation

Our 45° flanged bends are produced using internationally advanced centrifugal casting technology supported by fully automated production lines (annual output: 100,000 tons). Every bend complies with ISO 2531, EN 545, and GB/T 13295. From high-purity pig iron to finished goods, we enforce full-process quality control: spectrometers verify melt chemistry, hydrostatic testing machines check pressure resistance, and each unit undergoes airtightness and seismic performance tests. With five invention patents and certified technical processes, we guarantee consistent bend radius, uniform wall thickness, precise flange flatness and superior ductility – even under repetitive stress or ground movement.
