Fire Fighting Pipe Fittings
Durable series of pipe fittings
Leyon is always focusing on research and development of malleable
iron fittings, grooved fittings,tubing and valves that are mainly
applied in such industries as fire protection, water supply,
construction industry, municipal engineering and petrochemical.
They are designed for fire protection, gas supply and water supply
even in other difficult areas to access.
Our series of pipe fittings are designed for fire protection, gas
supply and water supply even in other difficult areas to access.
Production and packaging process
Steps: The melting-casing- MAO
embryo-Polishing-Galvanized-Threading-Detection-Packaging
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.
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.
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.
Small packaging numbers, which is easier for handle; carefully
choosehigh 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.
