Chitoliro cha spral chomwe chili ndi chipilala chosayerekezeka ndi mphamvu ya astm A252

Chitoliro chazitsulo chowoneka bwino champhamvu chosayerekezeka ndi mphamvu ya asitikali a252 mawonekedwe

Kufotokozera kwaifupi:

Izi zikutanthauza kuti mupereke muyezo wopanga mapaipi kuti afotokozere madzi, mpweya ndi mafuta mu mafakitale ndi mafakitale a masitolo.

Pali magawo awiri a mawonekedwe awiri a pss, psl 1 ndi psl 2, psl 2 ali ndi zofunikira zothandizira kaboni chimodzimodzi, zolimbitsa thupi, mphamvu yayikulu.

Ponena za kuyika kwapakatikati, machitidwe a mapaipi amtundu ndi chinthu chofunikira kwambiri chomwe chimagwira ntchito yofunika m'mafakitale osiyanasiyana. Kugwiritsa ntchito zida ndi maluso oyenera pakupanga chitoliro kumatsimikizira kulimba, nyonga ndi kudalirika, ndipochitoliro cha spral chisanu ASME A252kutsogolo kwa njirayi yaukadaulo. Mu blog ino, tionana mwachidule za mikhalidwe yapaderayi yomwe ili ndi vuto lomwe lakhala lopanda kanthu pa ntchito zomanga zamakono.

Kufotokozera Za Zogulitsa

Mphamvu zosayerekezereletsa:

ASTM A252chitoliro chowalaimapangidwa ndi chitsulo chowoneka bwino kwambiri chomwe chimakumana ndi miyezo ya ASMM A252. Muyezo umatipatsa mphamvu kwambiri komanso kulimba kwa mapaipi, ndikuwapangitsa kuti azigwiritsa ntchito mitundu yosiyanasiyana kuphatikizapo kufala kwa mafuta ndi mafuta, maziko a pight ndi zida zamadzi. Mafuta owoneka bwino amawonjezera mphamvu ndi kukana mapaipi kupita ku mphamvu zakunja, kuonetsetsa kuti amatha kupirira madera apamwamba komanso nyengo yovuta.

Oyenera kuchita bwino ndi mphamvu:

Chimodzi mwazabwino za Asm A252 owoneka bwino achitsulo ndi luso lake lalikulu pakugwiritsa ntchito. Kupanga kwake ndikosavuta kunyamula ndikugwira chifukwa cholemera chowala poyerekeza ndi zida zina za matope. Kuphatikiza apo, kusinthasintha kwa mapaipi awa kumathandizira kugwada, kuchepetsa zofunikira za zoseweretsa ndi mafupa. Sikuti nthawi yopulumutsa iyi imachepetsa ndalama, zimapangitsa kuti mtundu ukhale yankho la mtengo wokwera mtengo wa ntchito zosiyanasiyana.

Kuthetsa Kukana Kulanda:

Trussion ndi vuto lalikulu pamawu ojambula, makamaka m'makampani omwe amagwira mankhwala ndi zinthu zowononga. Muyezo wa Astme A252 amatsimikizira kuti mapaipi owoneka bwino owoneka bwino. Mapaipi awa amakhala ndi zokutira zoteteza monga epoxy kapena zinn omwe amakhala ngati cholepheretsa othandizira, kufalitsa moyo wawo wogwiritsira ntchito ndikuchepetsa ndalama zokonza. Izi ndizopindulitsa makamaka munthawi yapansi kapena zoyambira pomwe mapaipi amadziwika kuti ndi nyengo yowononga zachilengedwe.

Chachikulu chonyamula mphamvu:

Chimodzi china chofunikira kwambiri cha Astm A252 Spowar World Heels ndi mphamvu yake yabwino kwambiri. Tekinolory yotentha yogwiritsa ntchito popanga mapulogalamu imathandizira mphamvu ya chitoliro ndi kuthekera kupirira katundu wolemera. Kaya mulimbikidwe ogwiritsa ntchito mlatho, mapangidwe a pansi kapena matope a pansi pa matope, zimapangitsa kulephera kwa kulephera ndikuonetsetsa kuti ndi zotetezeka kwambiri.

Kukhazikika kwachilengedwe:

Mu Era pomwe kuteteza chilengedwe ndi kuda nkhawa padziko lonse lapansi, osasankha zinthu zomangamanga ndikofunikira. Chikato cha Spraur chomwe chili ndi chisanu ASM A252 amagwirizana ndi zoyeserera zokhazikika chifukwa cha kulimba kwake ndikubwezeretsanso. Mapaipi amakhala ndi moyo wautali ndipo amatha kubwezeretsedwa mosavuta kumapeto kwa moyo wawo, kuchepetsa kufunika kwa kuchotsera chatsopano pakuwononga zinyalala ndikuchepetsa kuwonongeka kwa kaboni ndi kaboni.

Pomaliza:

Chikato cha Spraul Chanch Astm Astm A25 adasinthira mafakitale omwe ali ndi mphamvu zake zazikulu, kukhazikika komanso kuwononga mtengo. Mapaipi awa amakumana kapena kupitilira mafakitale, kuwapangitsa kusankha koyamba m'mafakitale angapo. Zovuta zake zabwino kwambiri komanso kukana kutukuka kutsimikiziridwa kuti zikuyenda bwino kwa ntchito zomangamanga ndikuthandizira kupita patsogolo kwa malonda padziko lonse lapansi. Mwa kugwiritsa ntchito mapaipi awa, ntchito zomanga zimatha kukonza bwino, kuchepetsa mtengo ndikuwonetsetsa kuti kudalirika kwa nthawi yayitali potsatira zachilengedwe.

M'mbuyomu: Mapaipi owoneka bwino am'maso am'madzi am'mphepete

Ena: Chipika chapamwamba cha X65 Ssaw: yankho lalitali kwambiri lazoyenera komanso zodalirika za mapaisi
