Kubva payakagadzirwa makore anodarika zana apfuura, simbi isina simbi ndiyo yave kushandiswa nevakawanda uye kufarirwa pasi rose. Chromium yemukati inopa kuramba kwayo kubva mukuora. Kupokana kunogona kuratidzwa mukudzikisa maasidhi pamwe nekupokana nekurwiswa kwepitting mumishonga yechloride. Iine kushoma kwekugadzirisa zvinodiwa uye kupenya kwakajairika, zvichiita kuti ive yakanaka uye yakanakisa zvinhu zvepombi dzesimbi isina tsvina. Stainless simbi pombi inopiwa mumhando dzakasiyana dzechigadzirwa, kusanganisira welded pombi uye isina musono pombi. Iyo yakagadzirwa inogona kuchinja, ichibvumira kuti ishandiswe mumhando dzakasiyana-siyana. Stainless simbi pombi inoshandiswa nguva dzose nemafemu akawanda emaindasitiri. Mune ino blog positi, marudzi akasiyana emapombi esimbi asina tsvina maererano nemaitiro ekugadzira uye akasiyana mazinga ari kuzotaurwa. Pamusoro peizvozvo, iyi blog positi zvakare ine nzvimbo dzakasiyana dzekushandisa dzepombi dzesimbi isina tsvina mumaindasitiri akasiyana.

Mhando dzakasiyana dzeStainless Simbi MapaipiKubva paKugadzira Nzira

Iyo nzira yekugadzira mapaipi akaiswa welded kubva kune inoenderera coil kana ndiro inosanganisira kukungurutsa ndiro kana coil muchikamu chedenderedzwa nerubatsiro rwe roller kana kubhenda midziyo. Iyo yekuzadza zvinhu inogona kushandiswa muhukuru-hukuru kugadzirwa. Mapombi akaiswa anodhura zvishoma pane mapaipi asina musono, ane nzira yekugadzira yakawanda inodhura. Kunyangwe idzi nzira dzekugadzira, dzinoti nzira dzewelding dzakakosha zvikamu zvepombi dzesimbi isina tsvina, ruzivo rweidzi nzira dzewelding hazvitaurwe. Inogona kunge iri musoro weimwe blog post yedu. Tataura izvozvo, nzira dzekushongedza dzepombi dzesimbi isina tsvina dzinowanzoita sechipfupiso. Zvakakosha kuziva zvipfupiso izvi. Kune akati wandei welded matekiniki, akadai se:

• EFW-Magetsi fusion welding
• ERW-Magetsi kuramba welding
• HFW- High frequency welding
• SAW-Akanyura arc welding (spiral seam kana musono wakareba)

Kune zvakare mhando dzisina musono dzepombi dzesimbi dzisina tsvina mumisika. Mune zvimwe zvakadzama, zvichitevera kugadzirwa kwemagetsi kuramba welding, simbi inokungurutswa mukati mehurefu hwayo. Seamless pombi yehurefu hupi hupi hunogona kugadzirwa kuburikidza nesimbi extrusion. Mapaipi eERW ane majoini akasungwa pamwe chete nepakati pawo, nepo mapaipi asina musono ane majoini anoenda kureba kwepombi. Iko hakuna welding mumapombi asina musono sezvo maitiro ese ekugadzira anoitwa kuburikidza neakasimba kutenderera billet. Mumadhayamita akasiyana-siyana, mapaipi asina musono akapedzwa kumadziro emadziro uye dimensional specifications. Sezvo pasina musono pamuviri wepombi, mapombi aya anoshandiswa mukumanikidza kwakanyanya senge oiri uye gasi kutakurwa, maindasitiri, nekunatsa.

Iko kemikari yesimbi yakazara ine pesvedzero huru pamagumo-zvigadzirwa zvemakanika zvivakwa uye nzvimbo dzekushandisa. Saka, hazvishamisi kuti vanogona kuiswa muzvikamu maererano nemakemikari avo. Nekudaro, uchiedza kutsvaga giredhi reiyo pombi yesimbi isina tsvina, marudzi akasiyana-siyana emanomenclature anogona kusangana. Miyero inonyanya kushandiswa pakuronga mapaipi esimbi iDIN (German), EN, uye ASTM mamakisi. Munhu anogona kutarisa tafura yereferensi kuti awane mamakisi akaenzana. Tafura iri pazasi inopa ongororo inobatsira yezviyero zvakasiyana izvi.

Iri chirevo chekare chinoti indasitiri uye zviyero zvakabatanidzwa zvakanyanya. Iyo yekugadzira uye yekuyedzwa mhinduro inogona kusiyana nekuda kwekusiyana kweakasiyana masangano zviyero kune akasiyana siyana ekushandisa. Mutengi anofanira kutanga abata zvakakosha zveakasiyana maindasitiri maratidziro emapurojekiti avo, asati anyatsoita mabasa ekutenga. Iri zvakare chirevo chakarurama chepombi dzesimbi isina tsvina.

ASTM chidimbu cheAmerican Society for Testing and Materials. ASTM International inopa masevhisi zviyero uye zvigadzirwa zvemaindasitiri kune akasiyana maindasitiri. Iri sangano parizvino rakashandira 12000+ zviyero zvinoshandiswa mumabhizinesi kutenderera pasirese. Stainless simbi mapaipi uye fittings vari pasi pamusoro 100 zviyero. Kusiyana nemimwe miviri yakajairwa, ASTM inosanganisira dzinenge marudzi ese emapombi. Semuenzaniso, seAmerica pombi zvinhu, iyo yese spectrum yepombi inopiwa. Seamless kabhoni mapaipi ane akakodzera kutsanangurwa anoshandiswa kune yakakwirira-tembiricha masevhisi. Iyo ASTM zviyero zvinotsanangurwa nekutemerwa kwemakemikari kuumbwa uye mamwe maitiro ekugadzira ane chekuita nechinhu. Mimwe ASTM zvinhu zviyero zvinopihwa pazasi semuenzaniso.

• A106- Yepamusoro tembiricha masevhisi
• A335-Seamless ferritic simbi pombi (yepamusoro tembiricha)
• A333- Welded uye isina musono alloy simbi mapaipi (Nekuda kwakaderera tembiricha)
• A312- Yesevhisi yehuori uye yakanyanya tembiricha sevhisi, inotonhora yakashanda welded, yakatwasuka musono welded, uye mapaipi asina musono anoshandiswa.

Yakasiyana Typeof Stainless Simbi Mapaipi Kubva pane Mashandisirwo Nzvimbo

Sanitary Pipes:Mapaipi ehutsanana anogadzirwa nesimbi isina tsvina uye anoshandiswa muhutsanana hwepamusoro senge maapplication ane hutsanana. Iyi mhando yepombi inopihwa iyo inonyanya kukosha muindasitiri yekuyerera kwemvura inoshanda. Iyo pombi ine yakanakisa corrosion resistance uye haina ngura nekuda kwekureruka kwayo kugadzirisa. Yakasiyana-siyana yekushivirira miganho inotarwa zvichienderana nekushandisa. Mapaipi ehutsanana ane ASTMA270 mamakisi anowanzoshandiswa.

Mechanical Pipes:Zvikamu zvehallow, zvikamu zvinotakura, uye silinda zvikamu zvinowanzo shandiswa mumakanika pombi maapplication. Iwo makanika anogona kudzorwa zviri nyore kusvika kune yakafara siyana yezvikamu zvimiro zvakaita rectangular, sikweya, uye mamwe maumbirwo anowedzera kusvika kune akajairwa kana echinyakare maumbirwo. A554 uye ASTMA 511 ndiwo anonyanya kushandiswa giredhi mhando mumakanika maapplication. Iwo ane akanakisa machinability uye anoshandiswa mumashandisirwo akaita semotokari kana michina yekurima.

Mapaipi akapolishwa:Mapombi esimbi akakwenenzverwa anoshandiswa mudzimba dzepamba zvichienderana nezvakatsanangurwa. Mapombi akakwenenzverwa anobatsira mukuderedza kusakara uye kubvaruka pazvinhu zvinoshanda. Iyo inobatsirawo mukudzikisa kwekunamatira uye kusvibiswa kwenzvimbo dzakasiyana dzemidziyo. Iyo electropolished surface ine huwandu hwakawanda hwekushandisa. Simbi dzesimbi dzakakwenenzverwa mapaipi haadi chero yakawedzera kupfekedzwa. Mapombi akakwenenzverwa ane basa rakakosha uye rakakosha mukunakisa nekuvaka mashandisirwo.
