High Quality Coating Steel Pipe
High Quality Coating Steel Pipe
(1) Iyo nzira yekugadzira yesimbi isina musono pombi inogona kukamurwa kuita akati wandei ekutanga mapoka: inopisa yakakungurutswa (extrusion), inotonhora yakakungurutswa (kudhirowa) uye inopisa yakawedzera simbi pombi.
(2) Zvinoenderana nekugadzira nzira, welded pombi inogona kukamurwa kuita yakatwasuka musono yakashongedzerwa simbi pombi, spiral welded simbi pombi, ndiro coil butt welded simbi pombi uye welded pombi thermal kuwedzera simbi pombi.
Zvichienderana nechimiro, pombi dzesimbi dzinogona kukamurwa kuita: pombi inotenderera, pombi yakaenzana, pombi ine rectangular, octagonal, hexagonal, D-yakaita, pentagonal uye mamwe akakosha-akaumbwa simbi pombi, yakaoma chikamu simbi pombi, kaviri concave simbi pombi, mashanu petal. quincunx simbi mapaipi, conical simbi pombi, marata simbi pombi, melon mbeu simbi pombi, kaviri convex simbi pombi, nezvimwe.
Simbi pombi inogona kupatsanurwa kuita: simbi pombi pombi, simbi pombi yezvishandiso zvinopisa, simbi pombi yemakanika indasitiri, pombi yesimbi yepetroleum uye geological kuchera, mudziyo wesimbi pombi, simbi pombi yemakemikari indasitiri, simbi pombi yechinangwa chakakosha, nezvimwe. Anti-corrosion classification yemadziro emukati: kupeta mvura epoxy coating ipn8710 anti-corrosion uye kupeta fusion bonded epoxy powder anti-corrosion.
Kurongeka kwekunze kwemadziro anti-corrosion: kupeta 2PE / 3PE anti-corrosion, single-layer PE anti-corrosion uye kupeta epoxy marasha asphalt anti-corrosion.Anti corrosion standard: FBE epoxy powder anti-corrosion inofanirwa kuenderana neSY / t0315-2005 tekinoroji yekumisikidzwa kweimwe layer fusion yakasungirirwa epoxy poda yekunze yekupfeka yepombi yesimbi, 2PE / 3PE anti-corrosion ichaenderana neGB / t23257-2009 tekinoroji standard ye polyethylene yekunze yakavharwa yepombi yesimbi yakavigwa, anti-corrosion pamusoro pekubvisa ngura: jecha rinoputika pamusoro pekunze kwepombi yesimbi richasvika SA2 1/2 maererano nezvinodiwa zveGB / t8923-2008, uye kudzika kwezviyo zveancho pa pamusoro pepombi yesimbi inofanira kuva 40-100 μ m.
Zvinhu zvekutanga zvemapombi esimbi anorwisa-corrosion anosanganisira spiral pombi, seam pombi dzakatwasuka, mapaipi asina musono, nezvimwewo kuChina, anoshandiswa zvakanyanya muminda yeinjiniya yepombi sekufambisa kwemvura kureba, peturu, indasitiri yemakemikari, gasi rechisikigo, kupisa. , kucheneswa kwetsvina, chitubu chemvura, zambuko, chimiro chesimbi, kutapurirana kwemvura yemugungwa nekuputira.
Pamusoro pekuvandudza hupenyu hwesevhisi yepombi yesimbi kuburikidza ne-anti-corrosion, inoratidzwawo mune zvinotevera zvinhu:
1. Batanidza simba remagetsi repombi yesimbi pamwe nekudzivirira kwekuora kwepurasitiki;
2. Kuvhara kwekunze kwemadziro kunodarika 2.5mm, kusingagadziriswi nekukwenya uye kudhumhana;
3. Iko friction coefficient yemukati rusvingo iduku, 0.0081-0.091, kuderedza kushandiswa kwesimba;
4. Rusvingo rwemukati runosangana nemitemo yehutano yenyika;
5. Rusvingo rwomukati rwakatsetseka uye haruna nyore kuyera, nekuzvichenesa basa.
