Mabhenefiti emapaipi esimbi ecarbon akasungirirwa kwenguva refu akadzika arc mukushandisa mukuunganidza

Pane zvakanakira zvakawanda pakushandisa mapaipi esimbi esimbi esimbi anonyungudutswa kwenguva refu (LSAW) mukuita mapilling:

Murwi wesimbi weLSAW:
Mapaipi esimbi eLSAW (Longitudinal Submerged Arc Welding) anoshandiswa zvakanyanya semapaipi ekubatanidza zvinhu nekuda kwekugona kwawo kutsungirira mitoro inorema uye kupa rutsigiro rwechimiro. Mapaipi aya akagadzirwa kuburikidza nehurongwa hwekusanganisa zvinhu zvine simba guru, zvichikonzera chimiro chemapaipi chakasimba, chisina musono, uye chakafanana. Nzira yekusanganisa zvinhu inoenderera mberi inoshandiswa mumapaipi eLSAW inoita kuti pave nesimba rakawanda uye kuvimbika, zvichiita kuti akwanise kushandiswa pakusanganisa zvinhu.

Kuramba Kuora ne3LPE Yakaputirwa neLSAW pombi:
Kuti mapombi esimbi yeLSAW arambe akasimba, chifukidziro che3LPE (Three-Layer Polyethylene) chinowanzo shandiswa. Chifukidziro ichi chinopa simba rakanaka rekudzivirira ngura, chinodzivirira mapombi kubva muhunyoro, makemikari, uye kukuvara kwekunze. Mapombi matatu aya ane epoxy primer, copolymer glue, uye polyethylene topcoat, zvichigadzira chidziviriro chakasimba kubva mukuora. Izvi zvinoita kuti mapombi eLSAW akwanise kushandiswa pamusoro pevhu uye pasi pevhu, zvichiita kuti agare kwenguva refu.

Pipe Yakanakisisa yeLSAW WeldedMhinduro:
Kune mapurojekiti anoda mhinduro dzekuunganidza mapuranga dzinoshanda zvakanaka, dzinogara kwenguva refu, uye dzakavimbika,Mapaipi esimbi yekabhoni eLSAWndiyo sarudzo yepamusoro. Maumbirwo avo asina musono uye akafanana, pamwe chete ne3LPE coating, inoita kuti ngura isarambe zvakanaka uye ive nesimba risingaenzaniswi.

Kazhinji, kushandiswa kwemapaipi esimbi ecarbon akasungirirwa kwenguva refu akadzika midzi mukuisa mapaipi kunoita kuti pave nesimba, kugara kwenguva refu, kushanda zvakanaka pamari, kuchinjika, uye nyore kuisa, zvichiita kuti ave sarudzo yakakodzera kumapurojekiti akasiyana-siyana ekuvaka.
