1. Qonda i-spiral welded carbon steel pipe:

Kuvunguza ashiselwe carbon steel pipeyakhiwe ngokuvunguza futhi ishiselwe ngamakhoyili ensimbi.Inqubo yokukhiqiza eyingqayizivele yenza lawa mapayipi aqine futhi ahlale isikhathi eside, akwazi ukumelana nezingcindezi eziphezulu zangaphakathi nangaphandle.Ikhono lokumelana nokugqwala kanye ne-deformation libuye lenze lifanelekele uhla olubanzi lwezinhlelo zokusebenza, kufaka phakathi amapayipi amanzi kanye ne-metal pipe welding.

2. Amashubhu kalayini wamanzi:

Ezinhlelweni zokusabalalisa amanzi, ukulethwa kwamanzi ahlanzekile ngendlela ephephile futhi ephumelelayo kubalulekile.Ipayipi le-Spiral welded carbon steel lifakazele ukuthi liyisinqumo esinokwethenjelwa samapayipi amanzi ngenxa yezakhiwo zalo ezimelana nokugqwala.Indawo ebushelelezi yala mapayipi inciphisa ukungqubuzana, iqinisekise ukugeleza kwamanzi njalo futhi kunciphisa ukuxokozela.Ukwengeza, amandla emvelo nokuqina kuqinisekisa ukuvikeleka ekuvuzeni, ukuphuka, kanye nokwehluleka kwesakhiwo, okuqinisekisa ukuqhubeka, ukuhlinzekwa kwamanzi okuthembekile.

3. Metal pipe welding:

Imboni yokushisela incike kakhulu ku-spiral welded carbon steel pipe ngezinhlelo zokusebenza ezihlukahlukene.Amandla angavamile nokuguquguquka kwala mapayipi kuwenza abe ekahle ekushiseleni amapayipi ensimbi.Kungakhathaliseki ukuthi kwakha amathange amakhulu okugcina, amapayipi athutha uwoyela negesi, noma izingxenye zesakhiwo ezindaweni zezimboni, amapayipi ensimbi ensimbi e-spiral ashiselwe adlala indima ebalulekile.Ukufana kwamajoyinti ahlanganisiwe kuqinisekisa ukuthembeka nokuphepha kwesakhiwo, kunciphisa isidingo sokugcinwa njalo noma ukulungiswa.

4. Izinzuzo kanye nezinzuzo:

4.1 Isixazululo esingabizi kakhulu: Ipayipi lensimbi le-Spiral welded carbon inikeza isixazululo esingabizi kakhulu samapayipi amanzi kanye nokushisela amapayipi ensimbi.Ukuqina kwazo kanye nokumelana nokugqwala kuqinisekisa impilo yesevisi ende, ngaleyo ndlela kunciphisa izindleko zokushintshwa nokugcinwa kwazo.

4.2 Kulula ukuyifaka: Ubuchwepheshe bokushisela okuvunguzayo obusetshenziswa enqubweni yokukhiqiza bungakhiqiza amapayipi amade naqhubekayo, anciphise isidingo sokuhlangana njalo.Lo mklamo owenziwe lula wenza inqubo yokufaka ibe lula, yonga isikhathi nomzamo.

4.3 Ukuguquguquka: Amapayipi ensimbi e-Spiral welded carbon steel ayatholakala ngezinhlobonhlobo zamadayamitha nogqinsi, okuwavumela ukuthi ajwayelane nezinhlelo zokusebenza ezihlukene.Zingenziwa ngokwezifiso ukuze zihlangabezane nezidingo ezithile zephrojekthi, zivumelane nezinhlobonhlobo zoketshezi, izingcindezi namazinga okushisa.

4.4 Ukuvikelwa kwemvelo: Insimbi ye-Carbon iyinto ekwazi ukugaywa kabusha enomthelela ekusimameni kwemvelo.Amapayipi ensimbi ane-spiral welded carbon steel angasetshenziswa kabusha futhi asetshenziswe kabusha, kuncishiswe imfucuza futhi kuvikelwe izinsiza zemvelo.

Ekuphetheni:

Amakhono kanye nezinzuzo Kuvunguza ashiselwe carbon steel amapayipi epayipi amanzi kanyeukushisela ipayipi lensimbiayikwazi ukubukelwa phansi.Ukudluliswa okuphumelelayo nokuthembekile kwamanzi noketshezi lwasezimbonini kuncike kakhulu ekuqineni kwazo, ukumelana nokugqwala kanye nokuzifaka kalula.Njengoba isidingo sengqalasizinda eqinile nengabizi silokhu sikhula, amapayipi ensimbi ensimbi ecijile eyi-spiral azohlala eyingxenye ebalulekile ekuqinisekiseni ukusebenza kahle kwezinhlelo zamanzi nezinqubo zezimboni emhlabeni wonke.
