How to test our malleable iron pipe fittings?
Steps: The melting-casing- MAO embryo-Polishing-Galvanized-Threading-Detection-Packaging
1. Blast-furnace smelting +electric furnace adjustment duplex smelting technology,
72 hours-3 sections-electric annealing technology, comprehensively
ensure our products’ quality to be the best.
2. Take”six check +two inspect+one examine” measures,
using Germany made FOUNDRY-MASTER Xline to
check each pack of liquid iron’s chemical composition,
ensure low defect rate and stable product quality.
3. Carefully choose multiple vendors, using Shanghai-made 99.99 high purity zinc,
remove all the impurities which is bad product quality control,
brighter surface, more fine zinc coat, better protective properties.
4. Small packaging numbers, which is easier for handle;
carefully choose high quality non-recycled plastic made double-woven bag,
make the product to be more break-resistant,
no need worry about broken bag during handing process.
