Exporter China Steel Welded Carbon Pipe
ExportCarbon Steel Pipe,China Steel Pipe,Yakaderera Carbon Simbi Pipe,welded pombi, kubva kuChina. Kambani yedu inoita zvekutengesa kunze kwenyika kwe welded simbi pombi uye seamless simbi pombi. Zviuru zvematani epombi dzesimbi dzakakandwa zvinotengeswa kunze kwenyika gore negore. Mapombi akasungwa anowanzo kutumirwa kunze kwenyika akakamurwa kuita LSAW uye SSAW. Unoziva here mutsauko uripo pakati peLSAW Pipe neSSAW Pipe?
LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), inonziwo SAWL pombi. Iko kutora ndiro yesimbi seyakagadzirwa, yoiumba nemuchina wekuumba, wobva waita maviri-mativi akanyudzwa arc welding. Kuburikidza nemaitiro aya iyo LSAW simbi pombi inowana yakanakisa ductility, weld kuoma, kufanana, plastiki uye chisimbiso chikuru.
Iyo LSAW pombi dhayamita yakakura kupfuura ERW, kazhinji kubva pa16 inch kusvika 60 inch, 406mm kusvika 1500mm. Kuita kwakanaka pane yakakwirira pressure resistance, uye yakaderera-tembiricha corrosion resistance.
Yakave yakashandiswa zvakanyanya mumafuta uye gasi mapaipi, inonyanya kudiwa yakakura dhayamita uye gobvu remadziro pombi ine simba rakakura uye kureba. Zvichakadaro mukuvaka chimiro chinoda kusimba kwakasimba, kurapwa kwemvura, indasitiri yekupisa, kuvaka bhiriji, etc. Zvinoenderana neAPI yakatarwa, iyo LSAW pombi (SAWL pombi kana JCOE pombi) yakanyatso kurongedzerwa mune yakakura scaled oiri uye gasi kutakura, muzviitiko izvo mapaipi kuyambuka guta, gungwa, nenzvimbo yemudhorobha. Aya ndiwo kirasi 1 uye kirasi 2 nzvimbo.
SSAW Pipe (Spiral Submerged Arc-Welding Pipe), inonziwo HSAW pombi (Helical SAW), welding line shape senge helix. Iri kushandisa iyo yakafanana welding tekinoroji ye Submerged Arc-Welding ine LSAW pombi. Zvakasiyana SSAW pombi ine spiral yakasungwa apo iyo LSAW iri kurebesa welded. Manufacturing process iri kukungurutsa simbi tambo, kuita kukunguruka kutungamira kuve nekona negwara repakati pombi, kuumba uye welding, saka welding seam iri mumutsara unotenderera.
Iyo SSAW pombi dhayamita dhayamita kubva pa20 inch kusvika 100 inch, 406 mm kusvika 2540 mm. The advantage chikamu tinogona kuwana dhayamita yakasiyana yeSSAW mapaipi ane saizi yakafanana yesimbi strip, pane yakafara application yezvakagadzirwa. simbi tambo, uye welding musono anofanira kudzivirira chekutanga kushushikana, kuita kwakanaka kutakura kushushikana.
Izvo zvisingabatsiri ndezvipimo zvakashata zvemuviri, welding seam urefu hwakareba kupfuura urefu hwepombi, zviri nyore kukonzera kukanganisa kwekutsemuka, mhepo yemhepo, cinder kubatanidzwa, chikamu chewelding, welding simba mukudhonza chimiro.
Kune oiri uye gasi pombi masisitimu, asi mune petroleum dhizaini, iyo SSAW pombi / HSAW pombi inogona kushandiswa chete mukirasi 3 uye kirasi 4 nzvimbo. Chimiro chekuvaka, kutakura kwemvura uye kurapwa kwetsvina, indasitiri yemafuta, zvivakwa nezvimwe.
Overview
Application
Iyo Inonyanya Kushandiswa kune simba uye kumanikidza zvikamu, uye kune zvakajairika chinangwa chiputi, mvura, gasi uye mhepo pombi.
