Environmental Protection Policy Resulted to Production Slow Down


Hello All Clients, Friends, Buyers, 

As you know Chinese environmental protection policy are imposing increasingly and strictly, our flange industry was suffered great impact, our factory was received inspection every week almost, and in each inspection the production must be stopped (at least 2 day stopped per week), under this series circumstances, the order delivery time will be longer than before time, per container will take 25 days or more to complete at least, hope you can understand this serious situation and support us continue. This year the environmental policy was caused us very very difficult, but whatever we must support it, you know Chinese air water pollute was very serious, now we are updating our technology to reach the new policy. We also will do our best to make delivery as soon as possible.

About Flanges Rating PN64 and PN63

Any one who noted the flanges rating difference between PN64 and PN63? As we known, for the flange norms of DIN, BS4504 and UNI, flanges rating is PN64 for the nominal pressure, but from EN1092-1 norm, the nominal pressure revised to PN63. EN1092-1 norm was published later than DIN, UNI and BS4504, so I think maybe in future, PN63 will be popular nominal pressure to instead of PN64, this is the difference, but nowadays, we both use PN63 and PN64 rating for flanges, and PN63 flange, PN64 flange, maybe have not so much difference, this is my discovery, for any mistakes, can leave comments to m, thanks a lot.

Pipe Flanges Rating in Different Norms

There were a lot of flanges standards in the world, DIN, EN1092-1, BS4504, ANSI, AWWA, UNI, JIS, SANS, GOST, NFE, ISO, AS, NS etc, even every country have their owned norms for pipe flanges, but in fact, the flanges norms can be separated to American norms and European Norms, the American norms have ANSI, API, AWWA, MSS etc norms for flanges, their rating use “LBS”, for example 75lbs, 150lbs, 300lbs, 600lbs, 900lbs, 1500lbs, 2500lbs etc, but for European norms, like DIN, EN1092-1, BS4504, UNI etc, the rating USE “PN”, for example PN6, PN10, PN16, PN25, PN40, PN63, PN64, PN100 etc, also for the Russian flanges of GOST 12820 and GOST 12821, they are similar to European norms, but use PNxx mPa, for example, PN0.6MPA, PN1.0MPA, PN1.6MPA, PN2.5MPA, PN4.0MPA. In africa, the main flanges standard is SANS1123 or SABS1123, it is South African norm, its rating is for 600kpa, 1000kpa, 1600kpa, 2500kpa, 4000kpa etc, also similar to European Norms, In China, before time, Chinese flanges are similar to CCCP, but recently years, Chinese flanges norms revised to European system, also use PN6-PN100 rating. The flanges ratings are very important for flanges application, correct flanges rating will keep the application safe.
