    Ekwakhiweni kwengqalasizinda, izinto ezisetshenziswayo zisebenzisa iqhaza elibalulekile ekufezekeni kwesikhathi eside nasekusebenzeni kwephrojekthi. Indwangu eyodwa ebaluleke kakhulu embonini yengqalasizinda yipayipi elivuthayo. Lawa mapayipi asetshenziswa kakhulu kwizicelo ezahlukahlukene ezifana nama-main mains namapayipi egesi, kanye nokucaciswa kwawo, kufaka phakathi amapayipi ase-welded kanye ne-welded and spiral kanye nolwandle, abucayi ekuqinisekiseni ukusebenza kwawo. Kule bhulogi, sizobheka ukujula okujulileKuvunguza welded Pipe Profitionnokubaluleka kwabo embonini yezokwakha.

    SIPiral Seam Pipeskwakhiwa kusetshenziswa indlela ebizwa ngokuthi yinqubo ye-Welding Chishon. Le nqubo ifaka ukusebenzisa amakhoyili asongwe ama-arouse ensimbi azokwakhiwa ngesimo se-cylindrical bese efakwa eceleni komthungo. Umphumela uba ipayipi elinamandla aphezulu nokuqina, okwenza kube lula ukuthola izicelo eziningi. La mapayipi asetshenziswaI-welded tubeUbuchwepheshe ngesikhathi sokwakha, ukuqinisekisa ukuthi bayamelana nezinto ezahlukahlukene zezemvelo kanye nezingcindezi, zizenze zilungele ukusetshenziswa ngaphansi komhlaba nangaphansi kwamanzi.

    Uma ucubungula imininingwane ebekiwe yepayipi eSpiral Seam, kubalulekile ukugxila ezintweni ezibalulekile ezifana nobubanzi, ubukhulu obudongeni kanye nebanga lezinto ezibonakalayo. Ububanzi bepayipi bunquma amandla alo okuhambisa uketshezi noma igesi, ngenkathi ubukhulu bodonga bubamba iqhaza elibalulekile ebuqothweni bayo bokuhleleka nokuphikiswa kwengcindezi. Ngaphezu kwalokho, ibanga lezinto ezibonakalayo libonisa ikhwalithi nokwakheka kwensimbi esetshenzisiwe futhi kungukucatshangelwa okubalulekile ekuqinisekiseni isikhathi eside nokusebenza kwepayipi kuhlelo lokusebenza olunikeziwe.

    Ekwakhiweni kweAmapayipi Amanzi Amkhulu, Amapayipi e-Siram Seam anezinzuzo eziningi. Amandla abo aphezulu aphezulu kanye nokumelana nokugqwala kwenza bahlele ngokuhambisa amanzi amabanga amade, kanti ukuguquguquka kwabo kuvumela ukufakwa okulula kwezithiyo nangezithiyo eziyinselele. Ngaphezu kwalokho, ukusetshenziswa kwamapayipi emthungo e-Spiral Seam kumapayipi wegesi wemvelo kuqinisekisa ukuthuthwa okuphephile nokusebenzayo kwegesi yemvelo, ukuhlinzeka ngemikhakha ebalulekile yemikhakha yokuhlala, yezentengiso nezezimboni.

    Spiral Steel Pipe

    Ngolunye uhlangothi lwengqalasizinda, ukucaciswa kwe-Spiral Seams kulawulwa ngamazinga nemigomo yokuqinisekisa izimboni ukuqinisekisa ikhwalithi nokusebenza kwawo. Isibonelo, i-American Petroleum Institute (API) ithuthukise amazinga wokwenza kanye nokusebenzisa ipayipi le-Spiral-Seam okushiwo izidingo zesayizi, amandla, nezinqubo zokuhlola. Ngaphezu kwalokho, umphakathi waseMelika wokuhlola nezinto zokwakha (i-ASTM) uhlinzeka ngokwakheka kwezinto ezibonakalayo kanye nemishini yokucaciswa kwempahla yamapayipi we-Spiral Seam ukuze uqinisekise ukuthembeka nokuhambisana kwabo nezindinganiso zezimboni.

    Ngokufundwa, ukucaciswa kwepayipi okuvuthayo okuvuthayo kubalulekile endimeni yabo ekwakhiweni kwengqalasizinda. Noma ngabe isetshenziselwa ama-main mains nomaImigqa yegesi, Lawa mapayipi anikela ngamandla angenakuqhathaniswa, ukuqina kanye nokuguquguquka, okwenza babaluleke kakhulu ezweni lanamuhla. Ngokunamathela kumazinga nemigomo yemboni, ukusetshenziswa kwamapayipi we-Spiral Seam kuqinisekisa ukuphepha kanye nokusebenza kahle kwezinhlelo ezibucayi zengqalasizinda, kuveze indlela yentuthuko esimeme kanye nentuthuko yenhlalo.
