Chithunzi cha SSAW

Mtengo wa SSAWndi chitoliro chachikulu cha m'mimba mwake chopangidwa kuchokera ku koyilo yachitsulo ndi yowotcherera ndi msoko wozungulira (helical) pogwiritsa ntchito kuwotcherera pansi pamadzi.SSAW imayimira Spiral Submerged Arc Welded, ndi mawu akuti "SSAW chitoliro tanthauzo" pogula nthawi zambiri amatanthauza njira yopangira ma spiral SAW ndi kukwanira kwake-maulendo akutali ndi ntchito zazikulu-OD.
Mapaipi athu a SSAW amapezeka mokulirapo (φ508mm mpaka φ1626mm) komanso makulidwe a makoma osiyanasiyana, kuwonetsetsa kudalirika pakadutsa-kutumiza madzimadzi akutali. Opangidwa motsatira miyezo ya API 5L, ISO, ndi ASTM, mapaipi awa amamangidwa kuti athe kupirira kupsinjika kwakukulu komanso malo ovuta.
Podzipereka pakupanga zinthu mwatsatanetsatane, Octal Pipe imakupatsirani njira zotsika mtengo-zopanda kusokoneza mtundu wake, zomwe zimatipangitsa kukhala ogwirizana nawo odalirika pazomwe mukufuna.

SSAW Welded Steel Pipe, yomwe imadziwikanso kuti Spiral Submerged Arc Welded Pipe, imapangidwa pogwiritsa ntchito-makoyilo achitsulo apamwamba kwambiri monga zopangira. Chitsulochi chimapangidwa mozungulira komanso chowotcherera pogwiritsa ntchito njira yowotcherera yomwe ili pansi pawiri{2}}waya. Njira yapadera imeneyi yowotcherera imathetsa kupanikizika kwapang'onopang'ono panthawi yowotcherera, kuonetsetsa kuti{4}}zowotcherera zimakhala zapamwamba kwambiri ndipo zimagwira bwino ntchito. Mapaipi a SSAW amagwiritsidwa ntchito kwambiri pama projekiti osiyanasiyana amapaipi, monga mayendedwe amafuta & gasi ndi zomangamanga.

SSAW Welding (Kuwotcherera Kawiri-Sided Submerged Arc)
Kuwotcherera kwa SSAWkawirikawiri amagwiritsakuwotcherera kwa arc (SAW)kuti apange msoko wolowera mokhazikika komanso wolumikizana bwino, ndipo mizere yambiri imagwiritsa ntchito-zowotcherera mbali ziwiri (ID/OD) pamagawo onse a polojekiti.

Kapangidwe ka mapaipi achitsulo a SSAW amatsata njira zapamwamba zopangira-zapamwamba komanso zogwira mtima. Njira zazikulu ndi izi:

• Kuyang'anira Zinthu Zopangira: -magiredi achitsulo apamwamba kwambiri, monga Q235, Q345, ndi magiredi a API 5L, amawunikiridwa kuti akutsatira miyezo yapadziko lonse (API, ISO, ASTM, ndi zina zotero).
• Kupanga: Zitsulo zachitsulo ndizozizira-zopangidwa mozungulira kuti zitsimikizike kuti zisamangidwe bwino.
• Kuwotcherera: Automatic double{0}}waya wolowa pansi pa arc welding amaonetsetsa kuti weld alowa bwino komanso nyonga yolumikizana.
• Kutentha Chithandizo: Mipope imadutsa njira zochizira kutentha (annealing kapena normalizing) kuti muchepetse kupsinjika ndikuwongolera makina.
• Kuyesa & Kuyang'ana: Zimaphatikizapo macheke amtundu, kuyang'ana kowoneka, kuyesa kwa akupanga (UT), ndi kuyesa kwa hydrostatic kuti zitsimikizire mtundu wa malonda ndi magwiridwe antchito.
• Chithandizo cha Pamwamba: Anti-zopaka zowononga dzimbiri monga 3PE ndi FBE zimayikidwa kuti mapaipi azikhala olimba m'malo ovuta.

• Diameter Yakunja (OD): φ508–φ1626 mm (20"–64")
• Makulidwe a Khoma (WT): 6.4-25.4 mm
• Utali: 8.0–18.5 m(26'–62'); kudula mwamakonda-ku-utali womwe ulipo
• Maphunziro Ofunika:

• GB/T 9711: L190–L625 (e.g., L245, L290, L320, L360, L415, L450, L485)
• Magiredi ena pa pempho la mafotokozedwe a projekiti
• Miyezo Yothandizira: API 5L, ISO 3183, GB/T 9711, ASTM, EN, BS, DIN, CSA, DNV (muyezo wamapaipi akunyanja)
• Kupanga:Spiral Submerged Arc Welded (SSAW), double-sided SAW (ID/OD), coil-feed with edge milling, automated seam tracking, pa-line NDT, hydrostatic test, beveling, ndi coating line integration
• Mapeto Omaliza / Zopaka:Zowoneka bwino kapena zopindika kumapeto kwa muyezo; zakunja3LPE/FBE/epoxy(zokutira zamkati mwakufuna kwa polojekiti); kuyika chizindikiro ndi kutumiza kunja
• Kuyang'ana & Zolemba:100% hydrotest; UT / RT pa muyezo kapena ITP; MTCEN 10204 3.1/3.2ndi zolemba zonse za NDT zilipo

LSAW vs HSAW (SSAW) Mapaipi: Kusiyana Kwakukulu

Kodi chitoliro cha SSAW chimagwira bwanji kuthamanga?

Pakuti SSAW/HSAW mzere chitoliro, kuthamanga umphumphu wotetezedwa ndi kulamuliramsoko wa helical: ogula amatchulafull-utali weld seam NDT (UT/RT malinga ndi polojekiti ya ITP)ndipo amafuna kuyesedwa kwa hydrostatic ngati kuli koyenera, kotero kuvomereza kumachokera pa kukhulupirika kwa msoko ndi umboni woyesera. Lamulo lothandiza pogula zinthu ndi: ngati ntchitoyo ili yoopsa-kuchiopsezo (kuchulukira kwambiri, ntchito yowawa, kapena kukhwimitsa zofuna za eni ake), khwimitsanikalasi/WT kusankha ndi msoko NDT kuchulukam'malo modalira zonena za "pressure performance".

Pamapulojekiti a SSAW/HSAW, "pass/fail" nthawi zambiri imakhala yokhudzana ndi mphamvu zonse-imabwera kuchilango chovomerezeka cha msoko. Ogula nthawi zambiri amatseka zinthu zitatu zofunika kwambiri, ndipo apa ndipamene Octal Pipe imayika ulamuliro ndi umboni.

• Kusasinthasintha kwa msoko (kupanga → kukhazikika kwa weld):Ubwino wa msoko wa helical umayamba musanayambe kuwotcherera. Ngati kupanga kozungulira sikukhazikika, mumawona pambuyo pakekuyendayenda kwa msoko, kugwedezeka kwa ovality, ndi mbiri ya mikanda yosiyana, zomwe zimabweretsa NDT yowonjezera ndikukonza zokambirana. Octal Pipe imayang'anira kakhazikitsidwe-ndipo imasunga zowotchera mkati mwa zenera lodziwika bwino kuti msoko usamafanane kuchokera pachitoliro choyambirira mpaka chomaliza.
• NDT kuchuluka komwe kuli umboni-(osati "tinayesa"):Zomwe ogula amafunsa kwenikweni ndi:Kodi msoko wa helical amawunikidwa utali wonse?

Q: Kodi pali kusiyana kotani pakati pa LSAW ndi HSAW mapaipi?

A: Mtengo wa LSAWamagwiritsa amsoko wowongoka kuchokera ku mbale, pameneHSAW (nthawi zambiri SSAW)amagwiritsa amsoko wa helical kuchokera ku coil; kusankha kawirikawiri amayendetsedwa ndiMtundu wa OD, kuvomereza kwatsatanetsatane wa projekiti, ndi kuchuluka kwa kuyendera pamsoko.

Q: Kodi chitoliro chonse cha SSAW ndi chiyani?

A:SSAW imayimiraSpiral Submerged Arc Weldedchitoliro, kutanthauza msoko wa helical wopangidwa ndikuwotcherera kwa arc (SAW).
