Spiral pombi dzinonyanya kushandiswa kuoiri uye echisikigo magasi mapaipi, uye iwo mataurirwo anoratidzwa nekunze dhayamita * madziro ukobvu.Spiral pombi dzinogona kusungirirwa kune rimwe divi kana mativi ese.Iyo welded pombi ichava nechokwadi chekuti mvura yekumanikidza bvunzo, kusimba kwesimba re weld uye kutonhora kwekukotama kuita kunosangana nezvinodiwa.
Surface treatment method:
1. Kuchenesa
Solvents uye emulsions zvinoshandiswa kuchenesa pamusoro pesimbi kubvisa mafuta, girisi, guruva, smoothing agent uye yakafanana organic matter, asi haigoni kubvisa ngura, oxide scale, welding flux, nezvimwewo pamusoro pesimbi, saka inongova. inoshandiswa seyeyero yekubatsira mukugadzira anti-corrosion.
2. Zvishandiso zvekubvisa ngura
Kutanga, shandisa mabhurashi ewaya uye mamwe maturusi ekupurudzira pamusoro pesimbi, iyo inogona kubvisa yakasununguka kana yakaomeswa oxide chiyero, ngura, welding slag, etc. Kubvisa ngura kwezvishandiso zvemaoko kunogona kusvika padanho reSa2, uye maturusi emagetsi anogona kusvika. iyo Sa3 level.
3. Kunhonga
Kazhinji, nzira mbiri dzemakemikari uye electrolysis dzinoshandiswa pakunhonga.Pipeline anticorrosion inoshandisa makemikari pickling, iyo inogona kubvisa oxide scale, ngura, uye machira ekare.Dzimwe nguva inogona kushandiswa sejecha uye kubvisa ngura.Kucheneswa kwemakemikari kunogona kuita kuti chitarisiko chisvike kune imwe nhanho yehutsanana uye kushata, asi anchor pateni yayo haina kudzika, uye zviri nyore kusvibisa mamiriro acho.
4. Kupfapfaidza (kukanda) kubvisa ngura
Kupfapfaidza (kukanda) kubvisa ngura ndiyo mota ine simba repamusoro inodhiraivha (kukanda) mapanga kuti itenderere nekumhanya kwazvo, zvekuti simbi yesimbi, simbi yekupfura, simbi wire chikamu, zvicherwa uye mamwe mabrasives anopfapfaidzwa (akandwa) pamusoro. pamusoro pepombi yesimbi pasi pesimba re centrifugal simba., Kwete chete inogona kubvisa zvachose ngura, oxides uye tsvina, asiwo pombi yesimbi inogona kusvika kune inodiwa yepakati roughness pasi pekuita kwehukasha hunotyisa uye kuputika kweabrasive.
Mushure mekupfapfaidza (kukanda) kubvisa ngura, kwete chete iyo yemuviri adsorption mhedzisiro yepombi yepamusoro inogona kuwedzerwa, asiwo mechanical adhesion effect ye-anti-corrosion layer uye pombi yepamusoro inogona kusimbiswa.Naizvozvo, kupfapfaidza (kukanda) kubvisa ngura inzira yakanaka yekubvisa ngura yepipeline anticorrosion.Kazhinji kutaura, kupfura kuputika (jecha) kubvisa ngura kunonyanya kushandiswa mukati nekunze kwepamusoro kurapwa kwepombi, uye kupfura kuputika (jecha) kubvisa ngura kunonyanya kushandiswa pakurapa kwepamusoro kwepombi.
National mwero spiral simbi pombi inonzi 9711.1 spiral simbi pombi, 9711.2 spiral simbi pombi, zvinhu classification: 16Mn spiral simbi pombi, Q345B spiral simbi pombi, L245 spiral simbi pombi, L360 spiral simbi pombi, X40-X80 spiral simbi pombi, main chinangwa, spiral simbi pombi yekuchenesa tsvina, kucheneswa kwemvura Spiral simbi pombi, spiral simbi pombi dzezvidyarwa zvemvura, spiral simbi pombi dzemagetsi ekugadzira makemikari mabhizinesi, spiral simbi pombi dzesimba renyukireya, spiral simbi pombi dzekufambisa mvura inopfuta, spiral simbi pombi dze. kufambisa zvinwiwa zvisingatsvi, pombi dzepasi rose dzakatenderedza simbi, uye Ministry of Petroleum standard SY/T5037 spiral Steel Pipe.Ichi chigadzirwa chinoshandisa inopisa-yakakungurutswa simbi tambo seyakagadzirwa zvinhu, inogadzirwa neyakajairwa inodziya spiral kuumba, uye inosungirirwa ne otomatiki yakanyudzwa arc welding process.Chigadzirwa chinoshandisa API SPEC 5L, EN10217, GB/T9711.1, GB/T9711.2 zviyero.Inonyanya kushandiswa muindasitiri yemafuta uye gasi rechisikigo kutakura zvinwiwa zvinopisa uye zvisingabatike zvinwiwa uye zvimiro zvesimbi.
