Production and packaging process for elbow malleable iron pipe fitting

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.

Packaging & Delivery details of npt elbows;

why choose us?

We imported the equipments from DISA Denmark, DJ AMF Japan, SINTOKOGIO Japan in the MI elbow productline, the product quality is very stable.
Spectrometer from Oxford Instruments is used to inspect the elbow’s quality

High heat value natural gas annealing furnace is used for production, we control the annealing process strictly, the elbow’s physical properties is improved
The close-grained, high strength, impeccable steel & plate scrap is used as the raw material, the reson is that the quality of the steel is always the starting point of excllent quality.

Accurate threads strictkly acc. to the precise standards like ASME, EU, BS, DIN, etc. There is accurate structure for the threads, in this way allows to the easily engage between thread length & straightness with threaded pipe.

The pipe fittings’ size ranging from 1/8” to 8”

Excellent toughness & long working life.

Smooth surface without any sand hole
zinc coating’s average thickness is higher than 86 um, which is specified in ASME, EN(70um), DIN(70um) and SI(78um)
