Stainless steel pipe fittings have certain corrosion resistance;stainless steel pipe fittings during welding,carbide precipitation after repeated heating can reduce corrosion resistance.Stainless steel pipe fittings widely used in chemical industry, chemical fertilizer, petroleum, medical machinery manufacturing.
Surface defects of raw materials,Small black spots on the surface of the area will affect the BQ property;Hardness is too low, polishing is not easy to shine, and hardness is too low.
Elbows should be stored in a dry and ventilated place in sequenc.Stainless steel elbow should be inspected as planned.The exposed processing surface should be kept clean, clean of dirt, and stored in a clean and dry place indoors.
The tensile strength of stainless steel elbow is greater than 530 N/mm is 2 times that of galvanized pipe, 3-4 times that of copper pipe, 8-10 times that of PPR pipe, and has good ductility and toughness
The stability of stainless steel pipeline effectively prevents pollution due to material reasons. Stainless steel pipeline strength is high, can withstand strong vibration and impact, with no water leakage, no burst, fire, seismic characteristics, and widely applicable, in addition to disinfection and sterilization, do not need to control the water quality.
Stainless steel pickling passivation treatment is mainly impregnated method, paste method, brushing method, spray method, cycle method, electro- chemical method and other 6 methods, among which, impregnation method, paste method, stainless steel elbow spray method is more suitable for stainless steel chemical ship and equipment pickling passivation.
