Umbhobho we-SSAW

umbhobho we-SSAWngumbhobho omkhulu -owenziwe ngentsimbi yentsimbi kwaye udityaniswe ngomthungo ojikelezayo (helical) usebenzisa ukuwelda kwearc.I-SSAW imele iSpiral Submerged Arc Welded, kunye negama elithi "SSAW umbhobho intsingiselo" ekuthengeni kudla ngokubhekisa kule ndlela yokuvelisa ye-SAW ejikelezayo kunye nokufaneleka kwayo{0}}uthumelo olude kunye neeprojekthi ezinkulu ze-OD.
Imibhobho yethu ye-SSAW ifumaneka kwiidayamitha ezinkulu (φ508mm ukuya ku-φ1626mm) kunye nobukhulu beendonga eziguquguqukayo, ziqinisekisa ukuthembeka kwithuba elide{2}}lokuhambisa ulwelo olude. Iveliswe ngokuthobela i-API 5L, i-ISO, kunye nemigangatho ye-ASTM, le mibhobho yakhelwe ukumelana noxinzelelo olunzima kunye neendawo ezinzima.
Ngokuzibophelela kwimveliso echanekileyo, i-Octal Pipe inikezela ngexabiso-izisombululo ezisebenzayo ngaphandle kokuthomalalisa umgangatho, isenza iqabane elithembekileyo kwiimfuno zakho zemibhobho.

I-SSAW Welded Steel Pipe, ekwaziwa njengeSpiral Submerged Arc Welded Pipe, iveliswa kusetyenziswa{0}}iikhoyili zentsimbi ezikumgangatho ophezulu njengemathiriyeli ekrwada. Ipleyiti yentsimbi yenziwa ngokujikeleza kwaye idityaniswe kusetyenziswa ubuchule bokuwelda obuphindwe kabini{2}}ngocingo olufakwe emanzini. Le ndlela yokuwelda ikhethekileyo iphelisa uxinzelelo ngexesha lenkqubo yokuwelda, iqinisekisa{4}}izinga eliphezulu le welds kunye nokusebenza okuzinzileyo. Imibhobho ye-SSAW isetyenziswa ngokubanzi kwiiprojekthi ezahlukeneyo zemibhobho, ezifana nokuthuthwa kweoyile negesi kunye neziseko zophuhliso.

Ukuwelda kwe-SSAW (I-Welding ephindwe kabini-eMacaleni e-Submerged Arc)
SSAW ukuweldangokuqhelekileyo isebenzisaukuwelda kwe-arc emanzini (SAW)ukwenza i-spiral seam enozinzo lokungena kunye nomgangatho odibeneyo ophinda-phindayo, kwaye imigca emininzi ifaka i-welding ephindwe kabini ({0}}sided welding (ID/OD) ngokwenkcazo yeprojekthi.

Inkqubo yokwenziwa kwemibhobho yentsimbi ye-SSAW ilandela ubuchule obuphezulu bomgangatho ophezulu{0} kunye nemveliso esebenzayo. Amanyathelo angundoqo aquka:

• Ukuhlolwa kwezinto ezikrwada:-Umgangatho ophezulu weentsimbi zentsimbi, ezifana ne-Q235, i-Q345, kunye ne-API 5L amabakala, zihlolwe ukuthotyelwa kwemigangatho yamazwe ngamazwe (API, ISO, ASTM, njl.).
• Ukubumba: Iikhoyili zentsimbi ziyabanda-zenziwe zibe yimilo ejikelezayo ukuqinisekisa ukulunga kolwakhiwo.
• Ukuwelda: Okuzenzekelayo -ngocingo oluntywiliselwe i-arc welding iqinisekisa ukungena okugqwesileyo kunye nokomelela okudibeneyo.
• Unyango lobushushu: Imibhobho ingena kwiinkqubo zokunyanga ukushisa (i-annealing okanye i-normalizing) ukukhulula uxinzelelo kunye nokuphucula iimpawu zomatshini.
• Uvavanyo kunye noHlolo: Kubandakanya ukuhlolwa kwe-dimensional, ukuhlolwa okubonakalayo, uvavanyo lwe-ultrasonic (UT), kunye novavanyo lwe-hydrostatic ukuqinisekisa umgangatho wemveliso kunye nokusebenza.
• Unyango loMphezulu: I-Anti{0}}i-corrosion coatings efana ne-3PE kunye ne-FBE isetyenziselwa ukunyusa ukuqina kwemibhobho kwiindawo ezinzima.

• Ububanzi bangaphandle (OD): φ508–φ1626 mm (20"–64")
• Ukutyeba kweendonga (WT): 6.4–25.4 mm
• Ubude: 8.0–18.5 m(26'–62'); ukusika ngokwesiko-ukuya{3}}ubude obukhoyo
• AmaBanga oMathiriyeli:
• API 5L:IBangaA–X90(PSL1 / PSL2)
• GB/T 9711: L190–L625 (e.g., L245, L290, L320, L360, L415, L450, L485)
• Amanye amabakala ngesicelo sokucaciswa kweprojekthi
• Imigangatho exhaswayo: I-API 5L, ISO 3183, GB/T 9711, ASTM, EN, BS, DIN, CSA, DNV (umgangatho wombhobho we-offshore)
• Ukuvelisa:I-Spiral Submerged Arc Welded (SSAW), i-SAW ephindwe kabini- emacala omabini (ID/OD), icoil{1}}ifidi ene-edge milling, i-automated seam tracking, kwi{2}}line NDT, uvavanyo lwe-hydrostatic, i-beveling, kunye nokudityaniswa komgca wokutyabeka.
• Ukugqiba Ukugqiba / Iingubo:Iziphelo ezicacileyo okanye ezibeveled ngokomgangatho ngamnye; ngaphandle3LPE/FBE/epoxy(iingubo zangaphakathi zikhethwa yiprojekthi); ukumakisha kunye nokupakishwa kwamanye amazwe
• Uhlolo & Amaxwebhu:100% hydrotest; UT/RT ngokomgangatho okanye ITP; MTCEN {0}/3.2kunye neerekhodi ezipheleleyo ze-NDT ezikhoyo

I-LSAW vs HSAW (SSAW) Imibhobho: Iiyantlukwano eziphambili

Umbhobho we-SSAW uluphatha njani uxinzelelo?

Umthamo woxinzelelouyilo{{0}sekwe-ixhomekeke kwiI-OD, ubukhulu bodonga, ibakala lentsimbi (i-SMYS / uxinzelelo oluvumelekileyo), into yoyilo, isibonelelo sokutya, kunye nobushushu bokusebenza.phantsi kwekhowudi/spec esebenzayo. Kuba umbhobho womgca we-SSAW/HSAW, ingqibelelo yoxinzelelo ikhuselekile ngokulawulaumthungo we-helical: abathengi bakhankanyeepheleleyo-ubude be-weld seam NDT (UT/RT ngokweprojekthi ye-ITP)kwaye ifuna uvavanyo lwe-hydrostatic xa kufanelekile, ngoko ke ukwamkelwa kusekelwe kwingqibelelo yomthungo ebhaliweyo kunye nobungqina bovavanyo. Umthetho osebenzayo ekuthengeni ngulo: ukuba inkonzo ingaphezulu{1}}kumngcipheko (uxinzelelo oluphezulu, inkonzo emuncu, okanye iimfuno ezingqongqo zomnini), qinisaibakala / ukhetho lwe-WT kunye nomthungo we-NDT ububanziendaweni yokuxhomekeka kumabango aqhelekileyo "oxinzelelo lokusebenza".

Kwiiprojekthi ze-SSAW/HSAW, "ukupasa/ukusilela" kunqabile malunga namabango amandla enziwe afana nalawo enziwe ngabenzi-yehla kuulwamkelo lomthungo. Abathengi bahlala betshixa kwizinto ezintathu eziphambili, kwaye kulapho kanye i-Octal Pipe ibeka khona ulawulo kunye nobungqina.

• Ukungaguquguquki komthungo (ukwenza → uzinzo lweweld):Umgangatho we-helical seam uqala ngaphambi kokuba udibanise. Ukuba ukwakheka kwe-spiral akuzinzanga, uyibona kamva njengeukuzulazula komthungo, i-ovality drift, kunye neprofayili ye-bead engalinganiyo, ethi ke ibangele i-NDT eyongezelelweyo kunye neengxoxo zokulungisa. Umbhobho we-Octal ulawula ukusetwa kokwenza{1}phezulu kwaye igcina iiparamitha zokuwelda ngaphakathi kwefestile echaziweyo ukuze umthungo uhlale ungaguquguquki ukusuka kumbhobho wokuqala ukuya kowokugqibela kwiqashiso.
• Umda we-NDT obubungqina bophicotho ({0}}hayi "senze uvavanyo"):Eyona nto ibuzwa ngabathengi kukuba:Ngaba i-helical seam ihlolwe ubude obupheleleyo? Yeyiphi indlela, kwaye sisiphi isiseko sokwamkelwa?Umbhobho we-Octal uyahambelanaUkhuseleko lwe-UT/RTkunye nomgaqo we-disposition (ukwamkela/{0}}uvavanyo/ukwala) kumgangatho olawulayo kunye neprojekthi ye-ITP, kwaye ibonelela ngobungqina bokuhlola njengenxalenye yepakethe yokukhulula{1}}le yilento ethintela indawo yokubamba iindawo kunye{2}}nophononongo lokuhlola kwakhona.
• Ukulandeleka koxwebhu olusindayo kwinyani yesayithi:Ukulahlwa okuninzi kwenzeka emva kokunikezelwa xa imibhobho sele ibekwe kwinqanaba kwaye umxhasi akakwazi ukudibanisaubushushu/ikhoyili → ukuphawulwa kombhobho → iingxelo ze-NDT/hydro → i-MTC. Umbhobho we-Octal uhambisa ipakethe elandelekayo (EN{1}}; 3.2 ngesicelo) enemephu yeqashiso, ngoko ke i-QA inokukhulula imathiriyeli ngaphandle kokuleqa amakhonkco angekhoyo.

Xa abathengi bebuza iumahluko phakathi kwemibhobho ye-LSAW kunye ne-HSAW, umbuzo wokwenyani awuyiyo kuphela "ipleyiti vs ikhoyili" - loluphi uhlobo lomthungo olucutha ukuvunywa, umngcipheko wommandla, kunye nokuvezwa kweshedyuli phantsi kwenkcazo yeprojekthi.

Umahluko ophambili ochaphazela ukuvunywa kunye nokwenziwa kwendawo

Ngaba ixabiso lombhobho we-SSAW{0}} liyasebenza?

Kubukhulu bedayamitha, i-SSAW ihlala inexabiso-iyasebenza kuba i-coil{1}isekelwe kwizixhaso zokubumbaimveliso eqhubekayo kunye nokusebenza okuzinzileyo, ephucula ngokwesiqhelo iixabiso-ixesha lokukhokela ibhalansikwiipakethe ezinkulu{{0} zeOD. Ixabiso lokwenyani lidla ngokungenaiindleko ezifakiweyo zizonke, hayi ugcino % lwebango: xa ukuhanjiswa kwenziwaidityaniswe ngamaqashiso/ubungakanani ukutshatisa umphambili wokusebenza, iikontraka zinciphisa ixesha lokuhlela, ukuhamba kwecrane, kunye nokumisa "ubungakanani obulahlekileyo".

Kuninzi lwethenda, i-SSAW iba "yindleko-esebenzayo" xa ithoba ungquzulwano lweprojekthi{1}}olumbalwa lophazamiseko, ukukhutshwa kwe-QA okugudileyo, kunye nokusebenza okuncinci kwendawo{2}}kunokuthembela kwixabiso leyunithi kuphela.

Umbhobho we-SSAW (HSAW) usoloko uchazwa xa imingeni yendawo yokusebenza imalungaukuphatha, ukugquma ingqibelelo, ukufaneleka{0}ukukhawuleza kwesantya, kunye nokukhupha amaphepha, kungekhona nje "amandla ombhobho." UkusukaUmbhobho we-Octalimboniselo yentengo, iphakheji elungileyo ye-SSAW yileyoiphila kwiimeko zesayithi kunye neendawo ezimbalwa zokubamba kunye nokusebenza kwakhona okuncinci, exhaswa bubungqina bokuhlola obunokuphicothwa.

I-Octal Pipe ixhasa ezi ndawo ngokutshixaulawulo lwe-dimensional (OD/ovality/straightness) kunye nesiphelo prep (PE/BE)ngaphambili, kunye nokuhambisa ngechongi ecacileyo ye-bundle ukuze abasebenzi bangachithi ixesha lokuhlela ubungakanani kwindawo yomsebenzi.
