Mapaipe a ntchentche

Kulumikizana kumapangidwa ndikukhomerera kumapota wina ndi mnzake ndikuzisindikiza pogwiritsa ntchito ma gaskes osiyanasiyana. Milandu imapangidwa nthawi zambiri ya aluminium, mkuwa, mkuwa kapena chitsulo cha kaboni. Zinthu zomwe amakonda kwambiri pakugwiritsa ntchito njira zambiri ndi zitsulo zopangidwa kaboni. Kuphatikiza apo, ma flanges amatha kukhazikitsidwa mkati mwa mitundu yosiyanasiyana ya zingwe. Nthawi zambiri, zinthu zodzikongoletsera zimasankhidwa monga momwe zimakhalira ndi zitoliro. Kusankhidwa kwa zinthuzi kumachitika kuti ateteze zoopsa za Galvanic. Kusankha koyenera kwa zinthu zomwe zimasinthidwa kumaganiziridwa malinga ndi miyezo ya A. 182.

Teses wowombedwa umapangidwa chifukwa cha Astm ASME B16.11 Miyezo. Miyezo imeneyi imakonzekereratu ndikusankha kuchuluka koyenera komanso kutentha, ma radiose komanso zinthu zofunika pakupanga ma tees. Kuphatikiza apo, miyezo ya B16.11 imangololedwa pa carbon ndi alloy zitsulo. Tesi owala bwino amatha kupangidwa m'magulu atatu opanikizika omwe ali; Kalasi 3000, kalasi 6000 ndi kalasi 9000.

Kubuula kwa cylindrical kumachepetsa kugwiritsa ntchito chofinya mopatura kwambiri monga; kutentha kwamphamvu kapena mawonekedwe apamwamba. Ma flanges awa amawombedwa pamapaipi kapena zowonjezera pogwiritsa ntchito butding yomwe imapangitsa kuti thupi likhale lokhazikika. Kusuntha kumalumikizana kumathandizanso kugwiritsa ntchito chifukwa cha mtengo wake wotsika. Samafuna kuti apolisi athetse bwino ngati mawongoleredwe.

Mantha ndi zigawo zomwe zimagwira ntchito ngati cholumikizira pakati pa mapaipi akulu, ma valves kapena mapampi. Ubwino wokwezeka kwambiri wa kugwiritsidwa ntchito mophweka kusokonekera kotsuka ndikuyang'ana kuderali cholumikizidwa ndi ma flanges. Ma flanges nthawi zambiri amapangidwa ndi kugwiritsa ntchito njira zoweta kapena zosokoneza. Makina a flange amapanga cholumikizira pakati pa zinthu zosiyanasiyana.

Chifukwa chake, kukhazikika kwa ma flanges kumasuka ndikosavuta. Komabe, mphamvu ya zowongoka ndi ziwiri mwa magawo awiri mwa atatu azomwe zidalimidwa. Zovuta zina zokhala ndi zopondera ndikuti ndizosatheka kukonza chingwe cha chiuno kapena kukonza matope chifukwa cha zotsalazo pazenera sizowongoka. Gulu lachitatu loyaka ndi zitsulo zopota. Malingaliro awa amagwiritsidwa ntchito pa mapaipi ang'onoang'ono omwe ayenera kulolera zopanikizana. Mphamvu ya ma swn the told imalumikizana ndi mavuto amkati ndi ofanana ndi ma flanges.

Kutanthauzira kwamitundu yoyaka kumachitika kudzera pa Asme B16.5. Chifukwa chake zimalumikizana ngati; Tsisi yolowerera, kutsikira, zitsulo zotsekemera, zopingasa, zopindika. Zovala zowoneka bwino ndizosavuta kuzindikira. Kubuka kwa cylindrica ndi radius pang'onopang'ono kumalumikizidwa ndi gawo lalikulu loperekera.
