Ezweni lamapayipi, igama elithi DSAW pipe livame ukuvela ezingxoxweni mayelana nemikhiqizo yensimbi ephezulu. DSAW, nomaI-Double Submerged Arc Welding, kuyindlela esetshenziselwa ukukhiqiza amapayipi amakhulu amakhulu, ikakhulukazi embonini kawoyela negesi, kanye nasezintweni zasolwandle nezakhiwo. Le bhulogi izobheka kabanzi ukuthi liyini ipayipi le-DSAW, inqubo yalo yokukhiqiza, kanye nezinzuzo zalo.
Inqubo yokukhiqiza amapayipi e-DSAW ibandakanya izinyathelo ezimbili ezibalulekile: ukwakhiwa kwamapayipi kanye nokushisela. Okokuqala, ishidi lensimbi eliyisicaba ligoqwe libe yisimo se-cylindrical. Imiphetho yeshidi ibe isilungiselelwa ukushiselwa. I-DSAW ihlukile ngoba isebenzisa ama-arcs amabili okushisela acwiliswa ngaphansi kongqimba lwe-granular flux. Lokhu akugcini nje ukuvikela i-weld ekungcoleni, kodwa futhi kuqinisekisa ukungena okujulile, okuholela ekuboshweni okuqinile, okuqinile.
Enye yezinzuzo eziyinhloko zamapayipi e-DSAW yikhono lawo lokumelana nezingcindezi eziphezulu kanye nezimo zemvelo ezimbi kakhulu. Lokhu kuzenza zibe zilungele ukuthutha uwoyela negesi amabanga amade, lapho ukwethembeka kuwukhiye. Ukwengeza, amapayipi e-DSAW aziwa ngokuqina kwezindonga zawo ezifanayo, okunomthelela ekuthembekeni kwesakhiwo nokusebenza kwawo.
Enye inzuzo yeIpayipi le-DSAWwukuthi iyonga imali. Le nqubo yokukhiqiza ingakhiqiza ipayipi elikhulu lobubanzi ngenani eliphansi kunezinye izindlela, njengepayipi elingenamthungo noma i-ERW (ipayipi elishiselwe ukumelana nogesi). Lokhu kwenza ipayipi le-DSAW libe inketho ekhangayo ezimbonini eziningi ezifuna ukulinganisa ikhwalithi nesabelomali.
Sengiphetha, amapayipi e-DSAW ayingxenye ebalulekile emikhakheni eyahlukene, ikakhulukazi amandla kanye nengqalasizinda. Ukwakhiwa kwazo okumazombezombe, ukusebenza kahle kwezindleko, kanye nekhono lokusingatha izimo ezinzima kuzenza zibe ukukhetha okuphezulu ezinhlelweni eziningi. Ukuqonda izinzuzo kanye nenqubo yokukhiqiza yamapayipi e-DSAW kungasiza izinkampani zenze izinqumo ezinolwazi lapho zikhetha isixazululo samapayipi samaphrojekthi azo.
