Square pombi izita re square pombi uye rectangular nyere, kureva, simbi pombi ine akaenzana uye asina kuenzana divi kureba. Iyo inogadzirwa neakakungurutswa strip simbi mushure mekuita kurapwa. Kazhinji, simbi yeshinda inosunungurwa, yakasimudzwa, yakasvibiswa uye yakasungirirwa kuti iite pombi yakatenderedzwa, yobva yakungurutswa kuita pombi yakaenzana kubva papombi yakatenderera, yobva yacheka muhurefu hunodiwa.

1. Kutsauka kunobvumirwa kwemadziro emadziro epombi yeskweya hakupfuurire kana kubvisa 10% yezita remadziro ukobvu kana ukobvu hwemadziro husingapfuuri 10mm, pamwe kana kubvisa 8% yehukobvu hwemadziro kana ukobvu hwemadziro hwawedzera. kupfuura 10mm, kunze kwekukobvu kwemadziro emakona nenzvimbo dzeweld.

2. Iyo yakajairwa yekutakura kureba yeskweya rectangular pombi ndeye 4000mm-12000mm, kazhinji 6000mm uye 12000mm. Iyo rectangular chubhu inotenderwa kuendesa zvipfupi uye zvisina kuisirwa kureba zvigadzirwa zvisingasviki 2000mm, uye zvakare inogona kuendeswa muchimiro che interface chubhu, asi Demander ichacheka iyo interface chubhu kana ichiishandisa. Huremu hwemapfupi geji uye asiri akagadziriswa gauge zvigadzirwa hazvipfuure 5% yehuwandu hwekutakura huwandu. Kune masikweya nguva machubhu ane theoretical huremu hunodarika 20kg / m, haingapfuure gumi muzana yehuwandu hwekutakura huwandu.

3. Kukombama kwedhigirii rekona rectangular pombi haifaniri kudarika 2mm pamamita, uye dhigirii rekukombama rose haringapfuuri 0.2% yehurefu hwose.

Zvinoenderana nemaitiro ekugadzira, masikweya machubhu akakamurwa kuita inopisa-yakakungurutswa isina sikweya machubhu, inotonhora inodhirowa seamless square machubhu, extruded seamless square machubhu uye welded square chubhu.

Iyo welded square pombi inokamurwa kuita

1. Zvinoenderana nemaitiro - arc welding square chubhu, kuramba welding square chubhu (yakakwira frequency uye yakaderera frequency), gasi welding square chubhu uye choto welding square chubhu.

2. Maererano ne weld - yakananga welded square pipe uye spiral welded square pipe.

Kuronga kwezvinhu

Square machubhu akakamurwa kuita akajairwa kabhoni simbi sikweya machubhu uye yakaderera alloy square machubhu zvinoenderana nezvinhu.

1. Ordinary carbon steel yakakamurwa kuita Q195, Q215, Q235, SS400, 20# simbi, 45# simbi, nezvimwewo.

2. Yakaderera alloy simbi yakakamurwa kuita Q345, 16Mn, Q390, St52-3, nezvimwewo.

Production standard classification

Square chubhu yakakamurwa kuita yenyika standard square chubhu, Japanese standard square chubhu, British standard square chubhu, American standard square chubhu, European standard square chubhu uye isiri-standard square chubhu zvinoenderana nemaitiro ekugadzira.

Section shape classification

Square mapaipi akaiswa muchikamu zvichienderana nechikamu chimiro:

1. Simple chikamu square chubhu: square chubhu, rectangular chubhu.

2. Square chubhu ine chikamu chakaoma: ruva rakaita square chubhu, yakavhurika square chubhu, corrugated square chubhu uye yakakosha-yakaumbwa square chubhu.

Surface treatment classification

Mapaipi epamativi akakamurwa kuita hot-dip galvanized square pombi, electro galvanized square pombi, oiled square pombi uye pickled square pombi zvinoenderana nepamusoro kurapwa.

Shandisa classification

Square machubhu anokamurwa nekushandiswa: masikweya machubhu ekushongedza, sikweya machubhu echishandiso chemuchina, masikweya chubhu eindasitiri yemakemikari, sikweya machubhu ekugadzirwa kwesimbi, masikweya machubhu ekuvaka ngarava, sikweya machubhu emotokari, masikweya machubhu e matanda esimbi nemakoramu, nemachubhu masikweya ezvinangwa zvakakosha.

Wall ukobvu classification

Rectangular machubhu akaiswa pasi pehukobvu hwemadziro: yakawedzera gobvu yakakomberedzwa rectangular chubhu, gobvu madziro ane rectangular machubhu uye matete-akavakirwa rectangular chubhu. Fekitori yedu ine tekinoroji yekugadzira pamusika, uye ine hunyanzvi. Kugamuchirwa shamwari dzepasirese kuti ubvunze. Tichaedza zvatinokwanisa kuti tisangane nezvido zvenyu zvakasiyana-siyana.
