Chiyambi:
Ma flange achitsulo ndi zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito polumikiza mapaipi, ma valve, mapampu, ndi zida zina m'mafakitale osiyanasiyana. Amapereka kulumikizidwa kotetezeka komanso kopanda kutayikira, kuonetsetsa kuti magwiridwe antchito ndi odalirika a machitidwe osiyanasiyana. Komabe, ndikofunikira kumvetsetsa kuti mayiko osiyanasiyana ali ndi miyezo yawoyawo yachitsulo kuti awonetsetse kuti amagwirizana komanso chitetezo. Mu blog iyi, tiwona momwe zitsulo za flange zimayendera m'maiko osiyanasiyana komanso momwe amagwiritsira ntchito.
Kumvetsetsa Miyezo ya Steel Flange:
Miyezo yachitsulo ya flange imatchula kukula, zida, ndi zofunikira zaukadaulo popanga ma flanges. Miyezo iyi imatsimikizira kugwirizana ndi kusinthasintha kwa ma flanges kuchokera kwa opanga osiyanasiyana padziko lonse lapansi. Tiyeni tifufuze pamiyezo yodziwika padziko lonse lapansi yachitsulo flange:
1. National Standard Flange (China - GB9112-2000):
The GB9112-2000 ndiye dziko muyezo flange ntchito China. Imakhala ndi magawo angapo, monga GB9113-2000 mpaka GB9123-2000. Miyezo iyi imaphimba mitundu yosiyanasiyana ya flanges, kuphatikiza Welding Neck (WN), Slip-On (SO), Blind (BL), Threaded (TH), Lap Joint (LJ), ndi Socket Welding (SW).
2. American Standard Flange (USA - ANSI B16.5, ANSI B16.47):
Muyezo wa ANSI B16.5 umagwiritsidwa ntchito kwambiri ku United States. Imaphimba ma flanges okhala ndi miyeso monga Class 150, 300, 600, 900, ndi 1500. Kuwonjezera apo, ANSI B16.47 imaphatikizapo ma flanges okhala ndi kukula kwakukulu ndi kupanikizika kwapamwamba, komwe kumapezeka mumitundu yosiyanasiyana monga WN, SO, BL, TH, LJ, ndi SW.
3. Japanese Standard Flange (Japan – JIS B2220):
Japan imatsatira muyezo wa JIS B2220 wama flanges achitsulo. Muyezo uwu umayika ma flange kukhala 5K, 10K, 16K, ndi 20K. Monga miyezo ina, imaphatikizanso mitundu yosiyanasiyana ya ma flanges monga PL, SO, ndi BL.
4. German Standard Flange (Germany – DIN):
Muyezo waku Germany wa flanges umatchedwa DIN. Muyezowu umaphatikizanso zinthu zosiyanasiyana monga DIN2527, 2543, 2545, 2566, 2572, 2573, 2576, 2631, 2632, 2633, 2634, ndi 2638. Izi zikuphatikiza mitundu ya flange, monga WPL, BL, BL.
5. Italian Standard Flange (Italy - UNI):
Italy itengera UNI muyezo wa flanges zitsulo, zomwe zikuphatikizapo UNI2276, 2277, 2278, 6083, 6084, 6088, 6089, 2299, 2280, 2281, 2282, ndi 2283 mitundu, kuphatikizapo WPLN, flange SO BL, ndi TH.
6. British Standard Flange (UK - BS4504):
British Standard Flange, yomwe imadziwikanso kuti BS4504, imagwiritsidwa ntchito ku United Kingdom. Zimatsimikizira kuyanjana ndi chitetezo pamakina a mapaipi aku Britain.
7. Miyezo ya Unduna wa Zamankhwala (China - HG):
Unduna wa Zamankhwala ku China udafotokozeranso mitundu ingapo yama flanges achitsulo, monga HG5010-52 mpaka HG5028-58, HGJ44-91 mpaka HGJ65-91, HG20592-97 (HG20593-97 mpaka HG20614-906), ndi HGJ44-91 mpaka HGJ65-91, HG20592-97 (HG20593-97 mpaka HG20614-906), ndi HG20614-906 (HG20616-97 mpaka HG20635-97). Miyezo iyi idapangidwira makamaka makampani opanga mankhwala.
8. Miyezo ya Dipatimenti Yamakina (China - JB/T):
Dipatimenti ya Mechanical ku China yakhazikitsanso miyezo yosiyanasiyana yazitsulo zazitsulo, monga JB81-94 mpaka JB86-94 ndi JB / T79-94 mpaka J. Miyezo iyi ikugwirizana ndi zofunikira zamakina.
Gulu la Jindalai Steel lili ndi mizere yamakono yopanga, kusungunula, kupanga ndi kutembenuza, okhazikika popanga m'mimba mwake yayikulu, kuwotcherera lathyathyathya, kuwotcherera matako ndi ma flanges opanikizika, etc., muyezo wa dziko, American standard, Japanese standard, British standard, Chijeremani chokhazikika komanso chosakhazikika, ndikuvomera zojambula makonda.
