Noocyada Tuubooyinka aan kala go 'lahayn:Tuubo aan kala go 'lahayn oo kululiyo Tuubo aan kala go 'lahayn oo qabow-rogmaday

Tuubooyinka birta ah ee aan kala go 'lahayn ayaa inta badan loo isticmaalaa codsiyada dhexroorka yar yar, badanaa ka yar 24 inji. Dhab ahaantii, waxaa si gaar ah loogu doorbidaa dhuumaha leh dhexroor ka hooseeya 150 mm (6 inji) sababtoo ah xooggooda sare, iska caabbinta cadaadiska, iyo qaab-dhismeedkooda isku midka ah.

Marka laga soo tago wax soo saarka cabbirka yar ee caadiga ah, waxaan sidoo kale bixinnaa tuubooyin bir ah oo dhexroor weyn leh oo aan kala go 'lahayn si ay u daboolaan shuruudaha injineernimada gaarka ah.

Iyada oo loo marayo habka wax soo saarka kulul ee la duubay, tuubooyinka aan kala go 'lahayn waxaa la soo saari karaa ilaa dhexroorka ugu badan ee dibadda oo ah 20 inji (508 mm). Si loo helo qeexitaanno waaweyn, waxaan qaadannaa hab ballaarin kulul, kaas oo suurtageliya soo saarista tuubooyin aan kala go' lahayn oo gaaraya 40 inji (1016 mm).

Habkan sameynta ee horumarsan wuxuu hubinayaa in xitaa tuubooyinka aan tolnayn ee aadka u weyn ay sii wadaan:

Saxnaanta cabbirka saxda ah
Waxqabadka farsamada ee aadka u fiican
Iska caabinta cadaadiska deggan
Joogteyn tayo leh oo la isku halleyn karo

Natiijo ahaan, annagatuubo aan xuduud lahaynxalalku waxay taageeri karaan codsiyo badan oo adag, laga bilaabo nidaamyada warshadaha ee caadiga ah ilaa mashaariicda tamarta iyo kaabayaasha dhaqaalaha ee baaxadda weyn.

Heerka Tuubada API 5L

API 5L waxaa ku jira Darajada B, Tuubada Api 5l X42, Tuubada Api 5l X46, Tuubada Api 5l X52, Tuubada Api 5l X56, Tuubada Api 5l X60, Tuubada Api 5l X65, Tuubada Api 5l X70, iyo Tuubada Api 5l X80. Marka darajadu sii korodho, shuruudaha ayaa sii adkaanaya—gaar ahaan marka la eego sifooyinka u dhigma kaarboonka iyo farsamada—si loo daboolo baahiyaha cadaadiska sare iyo codsiyada dhuumaha ee muhiimka ah.

Isla heerkaas, waxaa sidoo kale jira farqi u dhexeeya tuubooyinka aan kala go 'lahayn iyo kuwa la alxamay ee ku jira halabuurka kiimikada. Tuubooyinka alxamay waxay caadi ahaan ku xiran yihiin xadad adag oo ku saabsan kaarboonka iyo sulfur si loo hubiyo alxam wanaagsan iyo waxqabad la isku halleyn karo xaaladaha adeegga cadaadiska sare leh.

Fiiro gaar ah: PSL2, daba-galaha (R, N, Q, M) waa qayb ka mid ah qeexitaanka darajada.

Heerka Tilmaamaha: PSL1, PSL2

PSL (Heerka Faahfaahinta Badeecada) waxaa loo qaybiyaa PSL1 iyo PSL2, waxaana loo fahmi karaa inay yihiin heerar tayo oo kala duwan.

Labaduba kuma kala duwana oo keliya shuruudaha kormeerka, laakiin sidoo kale waxay ku kala duwan yihiin qaab-dhismeedka kiimikada iyo waxqabadka farsamada. Guud ahaan, PSL2 waxay isticmaashaa kontaroolo adag si ay u buuxiso shuruudaha adeegga ee aadka u baahan.

Tijaabada Saamaynta: Looma baahna PSL1; looga baahan yahay PSL2 (marka laga reebo X80 xaaladaha qaarkood)
Tijaabada Aan Wax Burburin Ahayn (NDT): Looma baahna PSL1; looga baahan yahay PSL2

Hababka NDT sida baaritaanka ultrasound ama raajada ayaa loo isticmaalaa in lagu ogaado cilladaha gudaha iyo in la hubiyo daacadnimada walxaha iyada oo aan waxyeello u geysanayn tuubada.

Hel cabbiro faahfaahsan iyo xigasho

Maxaad noogu Dooranaysaa Bixiyahaaga Tuubada Birta ah ee API 5L

Doorashada alaab-qeybiyaha saxda ah waxay si toos ah u saameysaa jadwalka mashruucaaga, kharashka, iyo tayada. Waa kan waxa naga soocay:

✔ Sahay Degan oo loogu talagalay Mashaariicda Weyn

Waxaan ilaalinaa awoodda wax soo saarka iyo kaydka joogtada ah si aan u taageerno dalabaadka badan iyo mashaariicda EPC ee muddada dheer iyada oo aan dib u dhac lahayn.

✔ Noocyada Buuxa ee Darajooyinka iyo Cabbirrada

Laga bilaabo Darajada B ilaa X80, tuubooyinka aan sinayn oo alxanka leh (ERW / LSAW / SSAW) ayaa laga heli karaa cabbirro iyo tilmaamo kala duwan si ay ula jaanqaadaan shuruudaha dhuumaha kala duwan.

✔ Xakamaynta Tayada Adag

Dhammaan alaabada waxaa lagu soo saaray iyadoo la raacayo heerarka API 5L PSL1 / PSL2, oo leh diiwaanno kormeer oo dhammaystiran iyo raad-raac si loo hubiyo isku halaynta codsiyada cadaadiska sare leh.

✔ Xalalka Dahaadhka Sare

Waxaan bixinaa FBE, 3PE, 3PP, CWC, iyo dahaarka gudaha, annagoo bixinayna ilaalin daxalka muddada dheer ah oo loogu talagalay deegaannada xeebta iyo kuwa badda.

✔ Bixinta Degdegga ah iyo Xulashooyinka Dabacsan

Iyada oo la adeegsanayo kayd diyaar ah iyo jadwal wax soo saar oo hufan, waxaan hubineynaa waqtiyada gaaban ee hogaaminta waxaanan taageernaa shuruudaha loo habeeyey (dhererka, dahaarka, baakadaha).

✔ Khibrad Dhoofinta Caalamiga ah

Khibrad ballaaran oo ku saabsan dhoofinta Koonfur-bari Aasiya, Bariga Dhexe, Afrika, iyo Latin Ameerika, iyadoo si cad loo fahmay heerarka caalamiga ah iyo baahiyaha mashruuca.

✔ Qiimaha Warshadda ee Tartanka leh

Sahay toos ah oo ka timid soo saaraha oo leh qaab-dhismeed kharash oo la hagaajiyay, taasoo kaa caawinaysa inaad tartan ku sii jirto tartanka iibka iyo iibsiga.

Hel Qiimayn Degdeg ah

Noo soo dir shuruudahaaga (darajada, cabbirka, tirada, meesha aad u socoto), kooxdeennuna waxay ku siin doontaa qiimeyn xirfadeed 12 saacadood gudahood.

2. U fiirso taxaddarrada ku saabsan tuubooyinka birta kaarboon si looga fogaado dabka, qaraxyada, iyo shilalka sunta.

3. Ha u bandhigin unugga heerkul sare ama walxo daxal leh (haddii aad u baahato inaad ku jirto xaalad noocaas ah, fadlan dooro tuubo u adkaysta heerkulka sare ama u adkaysta daxalka).

4. Dooro walxaha tuubooyinka, iyo qeexitaannada ku habboon deegaanka, Dhexdhexaadka, Cadaadiska iyo heerkulka.

5. Samee baaritaannada iyo baaritaannada lagama maarmaanka ah ka hor inta aan la isticmaalin si loo waafajiyo tayada.
