Fire Sprinkler Pipe Fittings Black Malleable Iron 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
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.
FM/UL Certification
UL certification and FM certification are quite authoritative
certifications for product technical standards and product quality
requirements, and their certification bodies are located in the
United States. UL certification is a certification related to
safety identification, which originated from the Underwriters
Laboratories in the United States. UL is the abbreviation of
Underwrites Laboratories Inc. in the United States. It is one of
the world’s large private organizations engaged in safety testing
and appraisal. It is an independent third-party inspection
organization and a non-profit, A professional organization that
conducts public safety experiments. It includes product inspection
and factory inspection; the compilation and issuance of materials
and standards; product safety certification and operating safety
certification.
Product advantage
1. We use excellent raw materials and have a strict quality
inspection system, which includes leakage testing, providing
metallurgical and processing control, using spectroscopy to
determine material quality, chemical analysis of varieties to
strictly control compliance, and using fine grained, high strength,
non-porous iron to produce the final castings. Because high quality
iron is the starting point of producing high quality pipe fittings.
2: precision thread machining, in line with precision standards,
such as ASME, EU, BS, DIN, etc. Threads have a precise
construction, so the length and straightness of the threads allow
them to easily engage threaded tubes.
At the same time, our pipe fittings have good toughness, long
service life, smooth surface without sand holes, and soaked with
anti-rust oil to strengthen anti-rust.
