Kuedzwa kweKuoma kwePombi yeSimbi yeCarbon: Gwaro reNyanzvi

Mukushanda kwezuva nezuva kwemuchina wesimbi kana panzvimbo yekuvaka, kuyedza kuomarara kunopfuura kungoongorora nguva dzose—ndiyo nzira inokurumidza yekuona kana pombi yakakodzera basa racho. Ungave uri kuongorora.LSAW yemutsetse une kumanikidzwa kwakanyanya kanazvikamu zvisina chinhuPamusana pefuremu yenhandare, kukosha kwekuoma kwayo kunokuudza chaizvo kuti simbi yakabatwa sei uye kuti ichaita sei kana yave kumanikidzwa.

Heino chokwadi chehunyanzvi chekuti tinochiyera sei uye kuti nei chichikosha kune zvaunofunga. 

Mufananidzo 1.Kuongororwa kwekuoma kwepombi yesimbi yekabhoni murabhoritari yedu.

Chikonzero Nei Tisingakwanise Kuregeredza Kuoma Kwepfungwa

Kuoma hakusi kungogumira pamusoro pemvura chete; asi inzira isingaparadzi yekunzwisisa mweya wepombi.

Kufungidzira Simba:Pane kubatana kwakananga pakati pekuomarara nesimba rekudhonza (Rm). Mumunda, tinowanzo shandisa mutemo wegunwe Rm≈ 3.45× HB kuti tiwane fungidziro yesimba nekukurumidza pasina kuda bvunzo yakazara yekudhonza.

Zvikanganiso pakurapa kupisa:Kana batch yeASTM A106 yaifanira kunge yakajairika asi ikabuda zvakanyanya, bvunzo inoratidza kuti mwero wekutonhora waive wakadzikira kana kuti tembiricha yechoto yaive isina kuenzana.

"Chisungo Chisina Simba" (Welds):Mumapaipi akasungirirwa seERW kana SSAW, nzvimbo ine njodzi yekupisa (HAZ). Kana nzvimbo iyi ikanyanya kuoma, inopwanyika. Mu "mafuta negasi" "sour service," weld yakasimba zvakanyanya isimba reHydrogen-Induced Cracking (HIC).

Zvinhu Zvitatu Zvikuru: Ndeipi Nzira Yaunofanira Kushandisa?

1. Brinell (HBW) – Yakanakisisa pakushandisa zvinhu zvakawanda

Kune mapurati esimbi asina kugadzirwa uye mapaipi ane madziro akakora, Brinell ndiyo inonyanya kushandiswa. Inoshandisa bhora retungsten carbide re10mm uye mutoro unorema (kusvika ku3000kg).

Nei ichishanda:Kupinda kukuru kwesimbi kunoratidza huwandu hwesimbi, zvichikupa kuverenga kwakawanda pane kusanzwisisika kwenzvimbo.

Fomura:

2. Rockwell (HRB/HRC) - Mambo weKugadzira

Kana uchida mhinduro mumasekonzi mashoma pamutsetse une ruzha rwakawanda, Rockwell ndiyo mhinduro. Inzira yekuverenga zvakananga isingade kuyerwa kwemaziso.

HRB:Yakanakira simbi dzisina kusimba dzakadai seQ235.

HRC:Zvinodiwa pasimbi dzemapaipi dzine simba guru (senge API 5L X70) kana zvikamu zvakadzimwa.

3. Vickers (HV) - Nyanzvi yeLab Precisionist

Vickers inoshandisa piramidhi yedhaimani uye inowanzo chengeterwa lab. Kana uchida kuyera kuomarara kwesimbi pakati pemusono wakamanikana weld kuti uwane nzvimbo chaiyo iyo simbi yakatyoka, Vickers ndiyo yega chishandiso chebasa racho.

Tafura Yekutarisa: Kuoma Kwakajairika neGiredhi

Kunyange zvazvo kukosha kweMTR (Mill Test Report) kwakasiyana, heano mabhenji atinotsvaga mumagiredhi akafanana:

Zano Renyanzvi: Kune nzvimbo dzeH2S "dzinonaka", NACE MR0175 mitemo inovhara kuomarara kwechinhu ichi.22 HRC (inenge 248 HV)kudzivirira Kutsemuka kweStress Corrosion.

Kudzivisa "Data Rakaipa": Mitemo Yekuedza Munda

Kuti uwane mhedzisiro inonyatsoenderana neongororo, unofanirwa kudzora mavariables:

1.Uraya Kupfeka:Haugone kuyedzapombi yakabatidzwakuburikidza ne zinc. Zinc yakapfava uye ichakupa pfundo rakakombama. Unofanira kukuya pamusoro kusvika pasi pesimbi.

2.Tarisa Ukobvu:Kana madziro ako akatetepa, "anvil effect" (kuoma kwekutsigira kwemuchina) ichabuda ropa mumhedzisiro yako. Madziro epombi yako anofanira kunge akakora kanenge kagumi kupfuura kudzika kwegomba.

3.Funga Nezvenzvimbo:Usabatanidza bvunzo dzako. Kurova kwega kwega kunoshanda - kunoomesa simbi yakaipoteredza. Chengeta nzvimbo dzako dzekuyedza dziri pakati pemadhayamita matatu kuti uverenge zvakachena uye zvakazvimirira.

Kuedza kuomarara ndiko kudzivirira kwako kukuru kubva pakukundikana kwezvinhu. Nekusarudza nzira chaiyo—Brinell yekusimba kwehukuru, Rockwell yekumhanya, kana Vickers yekuongororwa kwe forensic weld—unova nechokwadi chekuti pombi yako yesimbi yekabhoni inosangana nezvinodiwa zvekuchengetedza zveinjiniya yemazuva ano.
