01High-quality stainless steel threaded pipe fittings:
1. The crest of the thread should be sharp, even pitch and look shiny.
2. The crest of the thread can be touched by hand, it should be smooth and processing standard.
3. The front wall of the core of the stainless steel pipe fittings is uniform and the flow parts are smooth.
4. The pipe fittings are delivered after strict mechanical treatment, so the surface should be free of inclusions.
5. Low carbon content, corrosion resistance, oxidation resistance, strong toughness, and strong resistance to pressure.
02 Inferior stainless steel threaded pipe fittings:
1. The surface is rough, the thread crest is not sharp and thick, the pitch is uneven, the thread crest is sometimes damaged, and it is easy to leak.
2. The thread is not shiny
3. The core is crooked, the wall thickness is uneven, and it is easy to block after the fluid.
4. Rough surface, untreated surface, easy to be oxidized
5. High carbon content, easy to rust, poor toughness, and weak tensile strength.
