Production process of elbow fittings:

Select material (we preferred baosteel, tianjin TPCO, smoke treasure, baotou steel, Chang Bao, CRC steel raw materials, such as requirements within the outer diameter is smooth, uniform wall thickness, selection of high manganese steel pipe to ensure that products beautiful) - material inspection (measurement, chemical composition inspection) - storage - material cutting (leave enough machining allowance, removing iron and burr) - intermediate frequency heater variable diameter and bending forming (mold push every 48 hours after grinding, ensure dimensional tolerance control) - heat treatment (tempering process) - end processing (37.5 + 0.25) bevel Angle - visual inspection (appearance without injury, peeling,Pockmark) - chemical composition analysis (imported hand-held spectrometer) - dimensional inspection (outer diameter, wall thickness, ovality, straightness) - mechanical performance test (squashed, flaring) - sand (fine sand in order to ensure that the surface pitting not too - spray paint (environmental protection coating equipment coating surface evenly) - printing (code printer code on a black, white, bright font) - packing (fixed wooden cases or pallet packaging, packaging tapes, plastic film outside package water-proof, dust) - product check (forklift trucks, lifting transport, light with light, neat)
