Now the stainless steel pipe fittings Market products, the real phenomenon is serious, then how to distinguish between true and false stainless steel pipe fittings, Metal machine network that can be identified by the following points:
Carefully compare dental front and tooth distance, high-quality stainless steel pipe fittings:
1. The standard eye to see the sharp teeth, teeth distance evenly and bright.
2. Feel: teeth front smooth, processing depth specifications.
3. The core positive wall evenly, flow pieces unblocked.
4. The factory before the mechanical treatment, the surface without folder, sundries.
5. Low carbon content, decay resistance, oxidation resistance, toughness and strong resistance to pressure.
Conversely, shoddy stainless steel pipe fittings:
1. Coarse build, bad tooth front and thick, tooth distance is not standard, tooth front when damage, easy to leak.
2. The thread can not see luster, gray feel poor,
3. The core crooked, wall thickness unevenness, fluid after easy plugging.
4. Surface roughness, the surface is not processed, easy to be oxidized
5. High carbon content, not resistant to decay, poor toughness, weak tensile strength.
we have our own pipe fitting factory since 1998 ,which covers 100 acres. In 1998, we invested and set up a new flange factory. Up to now, we have a complete production system, and become a professional and competitive group in this field.
