Mwachidule
Cholinga chathu nthawi zonse ndi kukhutiritsa makasitomala athu popereka chithandizo chagolide, mtengo wapamwamba komanso mtundu wapamwamba wa API 5CT Casing Tubing. Potsatira malingaliro abizinesi a 'customer 1st, forge ahead', tikulandira makasitomala ochokera mnyumba mwanu ndi kunja kuti agwirizane nafe ndikukupatsani chithandizo chothandiza kwambiri! Tikuyembekezera kugwirizana ndi inu kuti tipindule pamodzi ndi chitukuko chapamwamba. Tinatsimikizira khalidwe, ngati makasitomala sanakhutire ndi khalidwe la mankhwala, mukhoza kubwerera mkati 7days ndi mayiko awo oyambirira.

Chofunikira Choyesa
Kuphatikiza pakuwonetsetsa kupangidwa kwamankhwala ndi makina amakina, mayeso a hydrostatic amachitidwa m'modzim'modzi, ndikuyesa kuphulika ndi kuwongolera kumachitika. . Kuphatikiza apo, pali zofunika zina za microstructure, kukula kwa tirigu, ndi decarburization wosanjikiza wa chitoliro chomalizidwa chachitsulo.
Tensile Test:
1. Pazinthu zachitsulo zomwe zimapangidwa, wopanga amayenera kuyesa mayeso. Kwa chitoliro chowotcherera chamagetsi, chomwe chimayikidwa pachosankha cha wopanga, kuyesa kwachitsulo kumatha kuchitidwa pa mbale yachitsulo yomwe imagwiritsidwa ntchito popanga chitoliro kapena perfomred pa chitoliro chachitsulo mwachindunji. Kuyesa kochitidwa pa chinthu kungagwiritsidwenso ntchito ngati kuyesa kwazinthu.
2. Machubu oyesera adzasankhidwa mwachisawawa. Pamene mayesero angapo akufunika, njira yotsatsira iwonetsetse kuti zitsanzo zomwe zatengedwa zikhoza kuyimira chiyambi ndi mapeto a kutentha kwa kutentha (ngati kuli koyenera) ndi malekezero onse a chubu. Pamene mayesero angapo akufunika, chitsanzocho chiyenera kutengedwa kuchokera ku machubu osiyanasiyana kupatula kuti chitsanzo cha chubu chokhuthala chikhoza kutengedwa kuchokera kumalekezero onse a chubu.
3. Chitsanzo cha chitoliro chosasunthika chikhoza kutengedwa pamalo aliwonse pamtunda wa chitoliro; chitsanzo chowotcherera chitoliro chiyenera kutengedwa pafupifupi 90 ° ku msoko wowotcherera, kapena posankha wopanga. Zitsanzo zimatengedwa pafupifupi kotala la m'lifupi mwake.
4. Ziribe kanthu kusanachitike komanso pambuyo poyesera, ngati kukonzekera kwachitsanzo kukupezeka kuti kuli kolakwika kapena palibe kusowa kwa zipangizo zomwe sizikugwirizana ndi cholinga cha kuyesa, chitsanzocho chikhoza kuchotsedwa ndikusinthidwa ndi chitsanzo china chopangidwa kuchokera ku chubu chomwecho.
5. Ngati kuyesa kwamphamvu koyimira gulu lazinthu sikukwaniritsa zofunikira, wopanga atha kutenga machubu ena atatu kuchokera mugulu lomwelo la machubu kuti awonenso.
Ngati zobwereza zonse za zitsanzozo zikukwaniritsa zofunikira, gulu la machubu ndiloyenera kupatula chubu losayenerera lomwe linayesedwa poyamba.
Ngati zitsanzo zingapo zayesedwa koyambirira kapena chimodzi kapena zingapo zoyesedwanso sizikukwaniritsa zofunikira, wopanga akhoza kuyang'ana gulu la machubu amodzi ndi amodzi.
Gulu lazinthu zokanidwa litha kutenthedwanso ndikusinthidwanso ngati gulu latsopano.
Mayeso a Flattening:
1. Chitsanzo choyesera chidzakhala mphete yoyesera kapena mapeto odulidwa osachepera 63.5mm (2-1 / 2in).
2. Zitsanzo zikhoza kudulidwa musanayambe chithandizo cha kutentha, koma malinga ndi kutentha komweko monga chitoliro chikuyimira. Ngati mayeso a batch agwiritsidwa ntchito, miyeso iyenera kutengedwa kuti izindikire mgwirizano pakati pa zitsanzo ndi chubu lachitsanzo. Ng'anjo iliyonse pagulu lililonse iyenera kuphwanyidwa.
3. Chitsanzocho chidzaphwanyidwa pakati pa mbale ziwiri zofanana. Pazoyeserera zilizonse zoyeserera, weld imodzi idaphwanyidwa pa 90 ° ndipo ina idaphwanyidwa pa 0 °. Chitsanzocho chiyenera kuphwanyidwa mpaka makoma a chubu agwirizane. Pamaso pa mtunda pakati pa mbale zofananira ndi zochepa kuposa mtengo wotchulidwa, palibe ming'alu kapena kusweka kuyenera kuwonekera mu gawo lililonse la chitsanzo. Pa nthawi yonse yopalasa, pasakhale dongosolo losauka, ma weld osakanizidwa, delamination, kuwotcha zitsulo, kapena kutulutsa zitsulo.
4. Ziribe kanthu kusanachitike komanso pambuyo poyesera, ngati kukonzekera kwachitsanzo kukupezeka kuti kuli kolakwika kapena palibe kusowa kwa zipangizo zomwe sizikugwirizana ndi cholinga cha kuyesa, chitsanzocho chikhoza kuchotsedwa ndikusinthidwa ndi chitsanzo china chopangidwa kuchokera ku chubu chomwecho.
5. Ngati chitsanzo chilichonse choyimira chubu sichikukwaniritsa zofunikira, wopanga angatenge chitsanzo kuchokera kumapeto komweko kwa chubu kuti ayesedwe mowonjezera mpaka zofunikirazo zikwaniritsidwe. Komabe, kutalika kwa chitoliro chomalizidwa pambuyo pa sampuli sikuyenera kukhala osachepera 80% ya kutalika koyambirira. Ngati chitsanzo chilichonse cha chubu choyimira gulu lazinthu sichikukwaniritsa zofunikira, wopanga atha kutenga machubu ena awiri kuchokera pagulu lazinthu ndikudula zitsanzozo kuti ayesenso. Ngati zotsatira za kubwereza izi zonse zikukwaniritsa zofunikira, gulu la machubu ndiloyenera kupatula chubu chomwe chinasankhidwa poyamba monga chitsanzo. Ngati zitsanzo zoyesereranso sizikukwaniritsa zofunikira, wopanga akhoza kuyesa machubu otsala a batch imodzi ndi imodzi. Posankha wopanga, gulu lililonse la machubu limatha kutenthedwanso ndikuyesedwanso ngati gulu latsopano la machubu.
Kuyesa Kwamphamvu:
1. Kwa machubu, mndandanda wa zitsanzo udzatengedwa kuchokera ku chigawo chilichonse (pokhapokha ngati ndondomeko zolembedwa zasonyezedwa kuti zikwaniritse zofunikira za malamulo). Ngati dongosolo lakhazikitsidwa pa A10 (SR16), kuyesako ndi kovomerezeka.
2. Pa casing, mapaipi 3 achitsulo ayenera kutengedwa pagulu lililonse kuti ayesedwe. Machubu oyesera adzasankhidwa mwachisawawa, ndipo njira yachitsanzo idzaonetsetsa kuti zitsanzo zomwe zaperekedwa zikhoza kuyimira chiyambi ndi mapeto a kayendedwe ka kutentha kwa kutentha ndi kutsogolo ndi kumbuyo kwa manja panthawi ya chithandizo cha kutentha.
3. Charpy V-notch impact test
4. Ziribe kanthu kusanachitike komanso pambuyo poyesera, ngati kukonzekera kwachitsanzo kukupezeka kuti kuli kolakwika kapena palibe kusowa kwa zipangizo zomwe sizikugwirizana ndi cholinga cha kuyesa, chitsanzocho chikhoza kuchotsedwa ndikusinthidwa ndi chitsanzo china chopangidwa kuchokera ku chubu chomwecho. Zitsanzo siziyenera kuganiziridwa kuti ndi zolakwika chifukwa chakuti sizikukwaniritsa zofunikira za mphamvu zomwe zimagwiritsidwa ntchito.
5. Ngati zotsatira za zitsanzo zoposa imodzi ndizochepa kuposa zomwe zimafunikira mphamvu zowonongeka, kapena zotsatira za chitsanzo chimodzi ndizochepa kuposa 2/3 ya zomwe zimafunikira mphamvu zowonongeka, zitsanzo zitatu zowonjezera zidzatengedwa kuchokera ku chidutswa chomwecho ndipo kuyesedwanso. Mphamvu yachitsanzo chilichonse yomwe yayesedwanso ikhala yokulirapo kapena yofanana ndi mphamvu yomwe yaperekedwa.
6. Ngati zotsatira za kuyesa kwina sizikugwirizana ndi zofunikira ndipo zikhalidwe za kuyesa kwatsopano sizikukwaniritsidwa, ndiye kuti zitsanzo zitatu zowonjezera zimatengedwa kuchokera ku zidutswa zitatu za batch. Ngati zina zonse zowonjezera zikukwaniritsa zofunikira, gululo ndiloyenera kupatula lomwe linalephera poyamba. Ngati zowonjezera zowonjezera zowonjezera sizikukwaniritsa zofunikira, wopanga angasankhe kuyang'ana zidutswa zotsalira za batchi imodzi ndi imodzi, kapena kutenthetsanso batchiyo ndikuyiyang'ana mu batchi yatsopano.
7. Ngati zambiri mwazinthu zitatu zoyambirira zomwe zimafunikira kutsimikizira gulu la ziyeneretso zikanidwa, kuyang'ananso sikuloledwa kutsimikizira kuti gulu la machubu ndiloyenera. Wopanga atha kusankha kuyang'ana magulu otsalawo pang'onopang'ono, kapena kutenthetsanso batch ndikuyiyang'ana mu batchi yatsopano..
Mayeso a Hydrostatic:
1. Chitoliro chilichonse chidzayesedwa ndi hydrostatic pressure test ya chitoliro chonse pambuyo pa kukhuthala (ngati kuli koyenera) ndi chithandizo chomaliza cha kutentha (ngati kuli koyenera), ndipo chidzafika pamtundu wodziwika bwino wa hydrostatic popanda kutaya. Nthawi yoyeserera yoyeserera idapangidwa osakwana 5s. Kwa mipope yowotcherera, ma welds a mapaipi aziyang'aniridwa ngati akutuluka pansi pa kukakamizidwa kwa mayeso. Pokhapokha ngati kuyezetsa kwa chitoliro chonse kwachitidwa pasadakhale pa kukanikiza komwe kumafunikira pa chitoliro chomaliza, fakitale yokonza ulusi iyenera kuyesa hydrostatic (kapena kukonza mayeso otero) pa chitoliro chonse.
2. Mipope yomwe imayenera kutenthedwa kutentha idzayesedwa ndi hydrostatic test pambuyo pa kutentha komaliza. Kuthamanga kwa mayeso a mapaipi onse okhala ndi malekezero a ulusi ayenera kukhala osachepera mayeso a ulusi ndi ma couplings.
3 .Pambuyo pokonza kukula kwa chitoliro chotsirizidwa chakumapeto ndi ziwalo zonse zazifupi zomwe zimatenthedwa ndi kutentha, kuyesedwa kwa hydrostatic kudzachitika pambuyo pa mapeto apansi kapena ulusi.
