Chitoliro cha X42 SSAW Spiral Welded Chubu

Chitoliro cha X42 SSAW Spiral Welded Tube Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Chidule ichi ndi kupereka muyezo wopanga mapaipi kuti azitha kutumiza madzi, gasi ndi mafuta m'mafakitale amafuta ndi gasi wachilengedwe.

Pali magawo awiri a zinthu zomwe zagulitsidwa, PSL 1 ndi PSL 2, PSL 2 ili ndi zofunikira zofunika pa carbon equivalent, notch strength, maximum voeld strength ndi tensile strength.

Pankhani ya mapaipi achitsulo, njira zosiyanasiyana zowotcherera zimagwiritsidwa ntchito kuti pakhale kulumikizana kwapamwamba komanso kodalirika. Njira imodzi yotereyi ndikuwotcherera kwa arc yozungulira pansi pamadzi(SAW), yomwe imagwira ntchito yofunika kwambiri popanga chitoliro cha X42 SSAW. Monga mtsogoleri wamakampani, Cangzhou Spiral Steel Pipe Group Co., Ltd., yodziwika ndi mtundu wake wa Wuzhou, imatsatira miyezo yapadziko lonse lapansi ndipo imaonetsetsa kuti zinthu zake (kuphatikiza chitoliro cholumikizidwa cha X42 spiral submerged arc welded) zikugwirizana ndi API Spec 5L, ASTM A139, ASTM A252 ndi EN 10219. Mu blog iyi tikufufuza dziko losangalatsa la chitoliro cha X42 SSAW, ndikuwunikira zabwino zogwiritsa ntchito spiral submerged arc welding popanga chitoliro cholumikizidwa cha spirally.

Dziwani zambiri za Spiral Submerged Arc Welding (SAW):

Kuwotcherera kwa arc kozungulira, komwe kumadziwikanso kuti SAW, ndi njira yapadera yowotcherera yomwe imagwiritsidwa ntchito popanga mapaipi ozungulira mongaChitoliro cha X42 SSAWNjirayi imaphatikizapo kusungunula waya wotuluka ndi chitsulo choyambira pogwiritsa ntchito kutentha komwe kumapangidwa ndi kuyaka kwa arc pakati pa waya ndi madzi otuluka pansi pa madzi otuluka. Madzi otuluka amagwira ntchito ngati chotchinga choteteza, kuteteza zodetsa mlengalenga kuti zisasokoneze njira yosokera. Njirayi ili ndi ubwino wambiri poyerekeza ndi njira zina zowotcherera.

Ubwino wa kuwotcherera kwa arc wozungulira pansi pa madzi:

1. Ma weld okhazikika komanso abwino kwambiri: Njira ya SAW yomwe imagwiritsidwa ntchito mu chitoliro cha X42 SSAW imapanga ma weld ofanana komanso abwino kwambiri. Pamene arc imamizidwa mu flux, imapanga malo olamulidwa omwe amateteza malo osokera ku zinthu zakunja, kuonetsetsa kuti malo olumikizirana ndi okhazikika komanso odalirika apangidwa. Izi zimapangitsa kuti mapaipi osokera ozungulira akhale amphamvu komanso olimba kwambiri.

Kuwerengera Kutalika kwa Kuwotcherera kwa Chitoliro Chozungulira

2. Kugwira ntchito bwino kwambiri: Kuwotcherera kwa arc pansi pa madzi ozungulira kumapereka ntchito yabwino kwambiri chifukwa cha momwe imagwirira ntchito yokha. Njirayi imaphatikizapo kudyetsa waya wowotcherera nthawi zonse, zomwe zimapangitsa kuti ntchito ichitike mwachangu komanso kukhala yolondola. Kuchuluka kwa malo oyikamo zinthu komanso kudalira pang'ono ntchito zamanja kumathandiza kuti ntchito iyende bwino komanso kuti ikhale yotsika mtengo.

3. Yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana: Chitoliro cha X42 SSAW chopangidwa ndi spiral submerged arc welding chimagwiritsidwa ntchito kwambiri m'mafakitale ambiri. Mapaipi awa amagwiritsidwa ntchito poyendetsa mafuta ndi gasi, mapaipi amadzi, pothandizira zomangamanga, poyika maziko, ndi zina zambiri. Kusinthasintha komanso kudalirika kwa chubu cha X42 SSAW kumapangitsa kuti chikhale choyenera kugwiritsidwa ntchito mofunikira.

4. Makhalidwe abwino a makina: Njira ya SAW imatsimikizira kuwongolera bwino magawo a kulumikiza panthawi yopanga mapaipi olumikizidwa a X42 spiral submerged arc. Kuwongolera kumeneku kumatha kuwonjezera mawonekedwe a makina, kuphatikizapo kulimba kwa impact, mphamvu yotulutsa ndi mphamvu yokoka. Zotsatira zake, mapaipi awa ali ndi kukana kwakukulu ku mphamvu zakunja ndipo ndi oyenera ngakhale m'malo ovuta.

Pomaliza:

Tikafufuza dziko la kulumikiza kwa arc submerged spiral mu kupanga mapaipi a X42 SSAW, zimamveka bwino chifukwa chake njira imeneyi imagwiritsidwa ntchito kwambiri mumakampani opanga zitsulo. Kulumikiza kwa arc submerged spiral kumapereka zabwino zambiri monga mipata yolumikizirana yokhazikika, kugwira ntchito bwino, kusinthasintha komanso kukonza bwino zinthu zamakanika, kuonetsetsa kuti mapaipi olumikizidwa mozungulira, monga mapaipi achitsulo a X42 SSAW opangidwa ndi Cangzhou Spiral Steel Pipe Group Co., Ltd., akukwaniritsa miyezo yapamwamba kwambiri. Chifukwa chake, pankhani yodalirika, kulimba komanso magwiridwe antchito, chubu cha X42 SSAW chimatsimikizira kukhala chisankho chabwino kwambiri pa ntchito zosiyanasiyana zamafakitale.
