kabhoni simbi Rectangular tubing, Iyo imhando yehollow square cross section light thin-wall simbi pombi, inozivikanwawo sesimbi firiji bend chikamu.Iyo inogadzirwa neQ235 inopisa yakakungurutswa kana kutonhora yakakungurutswa simbi kana coil ndiro sechinhu chepasi nekutonhora kukotama kuumba uyezve nepamusoro frequency welding yakagadzirwa neskweya chikamu chimiro uye saizi yesimbi.Pamusoro pekukora kwemadziro, saizi yekona uye kumucheto kufuratira kweanopisa akakungurutswa akawedzera-gobvu madziro square chubhu anosvika kana kutopfuura mwero wekudzivirira welding inotonhora inogadzira square chubhu.
Carbon Steel Rectangular Tubing Classification
Seamless simbi chubhu uye welded simbi chubhu (welded pombi) inopisa yakakungurutswa isina sikweya chubhu, inotonhora inodhonzwa isina musono square chubhu, extrusion isina musono square chubhu, welded square chubhu.
Iyo welded square pombi yakakamurwa kuita:
1, zvinoenderana nemaitiro: arc welding square chubhu, kuramba welding square chubhu (yakakwira frequency, yakaderera frequency), gasi welding square chubhu, choto welding square chubhu;
2, maererano ne weld - yakatwasuka musono welding square pombi, spiral welding square pombi
Carbon Steel Rectangular Tubing Identification Method
1. Fake uye yakaderera rectangular pombi iri nyore kupeta.Kupeta mitsara yakasiyana-siyana yakatyoka yakaumbwa pamusoro pechubhu rectangular.Ichi chikanganiso chinowanzo mhanya kuburikidza nehurefu hwehurefu hwechigadzirwa.Chikonzero chekupeta ndechekuti nekuda kwekutsvaga kwekushanda kwepamusoro kwevagadziri vemanyepo uye vakaderera, huwandu hwekumanikidza hwakakura, nzeve inogadzirwa, iyo inotevera inopetwa inopetwa, chigadzirwa chakapetwa chinotsemuka mushure mekukotama, uye simba re simbi inoderedzwa zvikuru.
2. Kuonekwa kwekunyepedzera rectangular pombi kazhinji vane pockmarked phenomenon.Pockmarks hadzina kurongeka uye dzisina kuenzana hurema pamusoro pesimbi inokonzereswa nekupfeka kwakakomba kwe rolling groove.Groove rolling kazhinji inodarika mwero nekuda kwekutsvaga purofiti yevanogadzira shoddy rectangular pombi vanogadzira.
3. Iyo yepamusoro ye fake uye yakaderera rectangular chubhu iri nyore kugadzira mavanga.Pane zvikonzero zviviri:(1).Fake rectangular chubhu zvinhu hazvina yunifomu, tsvina.(2).Vagadziri veShoddy vanotungamira zvishandiso zviri nyore, zviri nyore kunamatira kusimbi, izvi tsvina
4. Shoddy material surface iri nyore kutsemuka, chikonzero ndechekuti billet yayo iadobe, adobe pores, adobe in the cooling process nekuda kwebasa rekushushikana kwekushisa, kuputika, mushure mekukunguruka kune kuputika.
5. Shoddy rectangular pombi iri nyore kukwenya, chikonzero ndechekuti shoddy rectangular pombi kugadzira michina iri nyore, nyore kugadzira burr, kukwenya pamusoro pesimbi.Kukwenya kwakadzika kunoderedza kusimba kwesimbi.
6. Fake rectangular chubhu isina simbi inopenya, tsvuku yakatsvuka kana zvikonzero zvemapoinzi maviri, billet yayo ndeye adobe. Iyo yekutenderera tembiricha yezvinhu zvisina kusimba haina mwero, tembiricha yavo yesimbi inoyerwa zvinoonekwa, saka haigone kukungurutswa maererano nezvakatsanangurwa. austenite nzvimbo, uye kushanda kwesimbi zvakasikwa hakugone kusvika pachiyero.
7. Mazariro akachinjika emachubhu enhema uye akaderera rectangular akaonda uye akaderera, ayo anowanzoita seakazadzwa nekusagutsikana.Chikonzero ndechekuti mugadziri ane kushivirira kukuru kwakashata uye kumanikidzwa kwemitsetse yekutanga yezvigadzirwa zvakapedzwa
8. Muchinjikwa weiyo fake rectangular chubhu ndeye oval, chikonzero ndechekuti mugadziri kuitira kuchengetedza zvinhu, kudzvanywa kweiyo yakapedzwa roller pamberi pezviviri yakakura, simba reiyi rebar rakaderedzwa zvakanyanya, asiwo. haina kuenderana nechiyero chechimiro saizi ye rebar.
9. Kuumbwa kwesimbi yepamusoro ndeye yunifomu, tonnage yemuchina wekuveura inotonhora yakakwirira, uye kuguma kwechiso chemusoro wekucheka kunonaka uye kwakarongeka.Pamusana pezvinhu zvakashata zvezvinhu zvenhema uye zvakaderera, chiso chekupedzisira chemusoro wekucheka kazhinji chine chiitiko chenyama inowira, kureva, iyo isina kuenzana uye isina-metallic luster.Uye nekuti mugadziri anocheka musoro zvishoma, musoro nemuswe zvinogona kuita senzeve huru.
10. Fake rectangular chubhu zvinhu zvine tsvina yakawanda, density yesimbi idiki, uye saizi haina kushivirira kana pasina vernier caliper, inogona kuyerwa nekuongororwa.Semuenzaniso, kune rebar 20, chiyero chenyika chinoti iyo yakanyanya kunaka kushivirira i5%.Pakuyera 9M, huremu hwayo huremu hwemudzi mumwechete ndeye 120kg, uye huremu hwayo hunofanira kuva: 120x (L-5%) = 114kg.Huremu chaihwo hwemudzi mumwechete wakayerwa idiki pane 114kg, saka isimbi yekunyepedzera%.Kazhinji, huwandu hwehuwandu hunoshanda zvirinani, zvakanyanya nekuda kwemhosho dzekuwedzera uye dzidziso yekugona kuitika.
11. Iyo yemukati dhayamita ye shoddy rectangular pombi inoshanduka zvakanyanya, nekuda kwezvikonzero zvinotevera: Steel tembiricha kusagadzikana ine Yin - Yang pamusoro.Kuumbwa kwesimbi hakuna kuenzana.Nekuti midziyo iri nyore, simba renheyo rakaderera, kubhuroka kweguyo kwakakura.Pachava nekuchinja kukuru mukati mevhiki imwe chete, kuitira kuti kusimbiswa hakusi yunifomu uye nyore kuputsika.
12. Chiratidzo uye kudhindwa kwemachubhu emhando yakanyatsoenderana.
13. Kupatsanuka kwemachubhu ane rectangular ane madhayamita ari pamusoro pe16 ari pamusoro peIM.
Iwo longitudinal mabara eshoddy simbi rebar anowanzo wavy.
Carbon Steel Rectangular Tubing A Formula To Calculate
2 [(a - d - 2 r + PI (d/r + 2) / 2 + (b - d - 2 r + PI (d/r + 2) / 2) x7.85 d (kg), a, b ye rectangular kureba nehupamhi (m), r (m) kumakona mana echubhu mhango, denderedzwa arc radius, d yemadziro ukobvu (mm).
