PN Meaning
PN is the nominal pressure, Represents the unit in the international system of units is 0.1MPa, In the engineering unit system is kgf/cm2.
The determination of nominal pressure is not only based on the maximum working pressure, According to the maximum operating temperature and material characteristics, And not just to meet the nominal pressure is greater than the working pressure. Flange also has a parameter is DN, DN is a parameter that indicates the size of the flange.
Use matters needing attention
- 1. In order to prevent eye corrosion due to the flange heating, Welding current should not be too large, Less than 20% carbon steel welding rod, Arc should not be too long, Interlayer cooling, Narrow welding bead.
- 2. Keep dry when used in welding rod, The titanium calcium type should be dried for 1 hours by 150℃, Low a hydrogen type should be dried for 1 hours by 200-250℃, Prevent the covering of viscous oil and other dirt, In order to avoid the increase of carbon content and the quality of the welding parts.
- 3. Welding of stainless steel flange pipe fittings, Repeated heating of precipitated carbide, Reducing the corrosion resistance and mechanical properties.
- 4. Chromium stainless steel pipe flange after welding of large flange American Standard hardening, Prone to crack. If the same type of chromium stainless steel welding rod (G202, G207) welding, Must be more than 300℃ degrees above the preheating and welding of about 700℃ degrees after the cooling treatment, If the welding parts can not be carried out after welding heat treatment, Stainless steel flange and pipe fittings (A107, A207) should be used.
- 5. Stainless steel flange, In order to improve the corrosion resistance and welding, the appropriate amount of stability elements Ti, Nb, Mo, etc. Welding is better than the chromium stainless steel flange. When using the same type of chromium stainless steel flange (G302, G307), Should be more than 200℃ degrees above the preheating and welding of about 800℃ degrees after the tempering treatment, If the welding parts can not be heat treatment, Stainless steel flange pipe (A107, A207) should be used.
- 6. Stainless steel flange pipe fittings, Welding electrode with good corrosion resistance and oxidation resistance, Widely used in chemical, fertilizer, oil, medical machinery manufacturing.
