Yakagadzirwa mukutevedzera API 5L, ISO, uye ASTM zviyero, mapaipi aya akavakwa kuti amire kudzvanyirira kwakanyanya uye nharaunda dzakaomarara.
Nekuzvipira mukugadzira zvinhu nemazvo, Octal Pipe inopa-mhinduro dzinoshanda pasina kukanganisa kunaka, zvichiita kuti tive shamwari inovimbwa nayo pane zvaunoda pombi.
Product Overview
SSAW Welded Steel Pipe, inozivikanwawo seSpiral Submerged Arc Welded Pipe, inogadzirwa pachishandiswa-makoiri emhando yepamusoro semidziyo. Simbi inogadzirwa zvine mutsindo uye inonamatwa pachishandiswa otomatiki kaviri-waya yakanyudzwa arc welding technique. Iyi nzira yakasiyana-siyana yewelding inobvisa kusagadzikana panguva yewelding, kuve nechokwadi chepamusoro-mawelds emhando yepamusoro uye kushanda kwakagadzikana. Mapombi eSSAW anoshandiswa zvakanyanya mumapurojekiti akasiyana epombi, sekutakura mafuta & gasi uye zvivakwa zvekuvaka.
sSAW pombi Manufacturing Process
SSAW Welding (Double-Sided Submerged Arc Welding)
SSAW weldingkazhinji anoshandisapasi pemvura arc welding (SAW)kugadzira spiral seam ine kupinda kwakadzikama uye kudzokororwa kunaka kwakabatana, uye mitsetse mizhinji inoshandisa kaviri-sided welding (ID/OD) maererano neprojekti yakatarwa.
Kugadzirwa kwepombi dzesimbi dzeSSAW kunotevera nzira dzepamusoro dzepamusoro-kugadzirwa kwemhando yepamusoro uye nemazvo. Matanho akakosha anosanganisira:
- Raw Material Inspection: -makoiri esimbi emhando yepamusoro, akadai seQ235, Q345, uye magiredhi eAPI 5L, anoongororwa kuti anoenderana here nezviyero zvepasi rose (API, ISO, ASTM, nezvimwewo).
- Kuumba: Makoiri esimbi anotonhora-anogadzirwa kuita spiral shapes kuti ave nechokwadi chechimiro chakanyanya kunaka.
- Welding: Otomatiki kaviri-waya yakanyudzwa arc welding inogonesa kupinda mukati nekusimba kwemajoini.
- Kupisa Kurapa: Mapombi anoitisa kupisa kupisa maitiro (annealing kana normalizing) kudzoreredza kushushikana uye kunatsiridza michina zvivakwa.
- Kuedza & Kuongorora: Inosanganisira dimensional cheki, ongororo yekuona, ultrasonic bvunzo (UT), uye hydrostatic kuyedza kuve nechokwadi chemhando yechigadzirwa uye kuita.
- Surface Treatment: Anti-machira ekuora akadai se3PE neFBE anoiswa kuti awedzere kusimba kwepombi munzvimbo dzakaoma.

Pombi yeSSAW inobata sei kumanikidza?
Pressure capacity ndiyodhizaini-zvakavakirwa-zvinoenderana neOD, kukora kwemadziro, simbi giredhi (SMYS/ inobvumirwa kushushikana), dhizaini chinhu, corrosion allowance, uye tembiricha yekushandisa.pasi pekodhi inoshanda/spec. Kune SSAW/HSAW mutsetse pombi, kumanikidza kutendeseka kunochengetedzwa nekudzora iyohelical musono: vatengi vanowanzo tsanangurayakazara-kureba weld seam NDT (UT/RT maererano neprojekti yeITP)uye zvinoda hydrostatic kuyedzwa kana zvichibvira, saka kugamuchirwa kunobva pane yakanyorwa musono kuvimbika uye bvunzo humbowo. Mutemo unoshanda pakutenga ndewekuti: kana sevhisi iripamusoro-ngozi (yakanyanya kudzvanywa, sevhisi inovava, kana kuomesera zvinodiwa nemuridzi), simbisagiredhi/WT kusarudzwa uye musono NDT chiyeropane kuvimba nezvinonzi "pressure performance" zvakajairwa.
SSAW Welding & Seam Quality Control (Chii cheVatengi Audit)
Pamapurojekiti eSSAW/HSAW, "pass/fail" kashoma kutaura nezvesimba rinowanikwa-zvinouyamusono kugamuchira kurangwa. Vatengi vanowanzo kiya pazvinhu zvitatu zvakakosha, uye iyi ndiyo chaiyo iyo Octal Pipe inoisa kutonga uye humbowo.
- Seam kusarongeka (kuumba → weld kugadzikana):Iyo helical seam quality inotanga isati yave welding. Kana kuumbwa kwe spiral kusina kugadzikana, unozviona gare gare seseam kudzungaira, ovality drift, uye isina kuenzana bead profile, iyo inobva yatanga kuwedzera NDT uye kugadzirisa nhaurirano.

Mumatenda mazhinji, SSAW inova "mutengo-inoshanda" kana ichinge yadzikisa kupesana kweprojekiti{1}}kushoma kuvhiringika kwehurongwa, kuburitswa kweQA kuri nyore, uye kushomeka kwenzvimbo-pane kuvimba nemutengo wakaderera wega.
SSAW Pipe mu-World Worksite Environment
SSAW (HSAW) pombi inowanzotsanangurwa kana matambudziko enzvimbo yebasa ari pamusorokubata, kupfekedza kunaka, kukwana{{0}kuchimbidza, uye kuburitsa mapepa, kwete chete "simba repombi." KubvaOctal Pipe's procurement view, iyo chaiyo SSAW package ndiyo iyoinorarama nemamiriro epasaiti ine mashoma ekubata uye kushoma rework, inotsigirwa neuchapupu hwekuongorora hunoongororwa.
- Kubvumidzwa kupinda (nzira dzemumakomo / nhete ROW / kusimudza kushoma):
- Dambudziko repanzvimbo yebasa harisi rekushikirira pacharo-ndironguva yekuenzanisa: isina kuenzana pasi uye mapfupi ekusimudza mafambiro anowedzera nyaya dzakadaiovality, kutwasanuka kwekutwasanuka, uye kusagadzikana kwemagumo mamiriro, izvo zvinononotsa kukwana-uye kuwedzera kururamisa kwekumanikidzira. Octal Pipe inowanzo tsigira aya masaiti nekuvharadimensional controls (OD/ovality/straightness) uye kupera prep (PE/BE)kumberi, uye kutakura neakajeka bundle chiziviso kuti vashandi vasatambise nguva kuronga saizi pamberi pebasa.
- Ivhu rakanyorova (kuyambuka nzizi / manyoro / mvura yakakwira yepasi):
- Mukubata madhaka nekudzikira-mu, kurwadziwa kunowanzoitika ndekwekukanganisa kwekuvhara uye zororo rekugadzirisa basa rekuita, iyo inogona kunonoka kudzosera kumashure uye kukonzeresa kuongororwa kwakadzokororwa. Octal Pipe inogona kuwiriranisa odha nepasuru yekubatisa inoshanda (kana yatsanangurwa) uye kupa magwaro anotsigira ekuburitsa{1}}kuti timu yesaiti isarambe ichiratidza kubvuma mushure mekunge pombi yatoitwa.
- -zvakapararira (zvakavhurika-kuvakwa kwemunda / kureba-kutakurwa kwezvinhu):
- Kubudirira kunowanzorasika kunekukurumidza kuburitsa, kwete kumhanya kwekugadzira{0}}zvirongwa zvinobatikamabundle akasanganiswa, anoshaikwa ekutarisisa zvinongedzo, kana mapeji ekuongorora asina mepu zvakachena kumaki epombi.. Apa ndipo apo Octal Pipe inotarisisa pakutakura chirango: kupatsanura mijenya, kucherekedza kwakajeka, uye gwaro paki rinobatanidza.kupisa/coil → kumaka pombi → humbowo hwekuongorora → MTC, kuderedza QA kubata mapoinzi panguva yekuiswa.
- Mahwindo ebasa mapfupi (mikoto yemudhorobha / mashifiti ehusiku / mvumo-yebasa shoma):
- Kana vashandi vaine maawa mashoma, chero kusawirirana kunodhura:bevel kusawirirana, dimensional kusiyanisa, kana kusajeka kwekutarisa chiyeroinokurumidza kushanduka kuita kugaya / kushandazve uye mahwindo akapotsa. Vatengi vanowanzo tsanangura zvakati tsvikiti -zvinodikanwa (kushivirira, kupera kwekupedzisira, kureba nzira), uye Octal Pipe inogona kurongedza zvinhu zvinoenderana nemarekodhi ekuongorora anobatsira saiti QA kuburitswa pasina kunonoka.
