Warshada Xirfadlayaasha ah ee S45c E355 Gr 20 Dhuumaha Birta ah ee Birta ah ee Mo40 Tubada Honed iyo Dhuumaha
Sharaxaad Gaaban:
Tuubooyinka birta makaanikada ah waxaa loo isticmaalaa mashiinada ama qaybaha la sameeyay ee warshadaha, baabuurta, mishiinada beeraha, diyaaradaha, gaadiidka, maaraynta alaabta iyo qalabka guriga.Waxa loo soo saaray si sax ah dhexroorka ka baxsan iyo cabbirka dhumucda gidaarka.
Laga soo bilaabo dhowrkii sano ee la soo dhaafay, shirkadeena waxay nuugtay oo u dheefshiiday tignoolajiyada casriga ah si isku mid ah gudaha iyo dibaddaba.Dhanka kale, ururkayaga shaqaale koox ka mid ah khubarada u heellan kobaca Warshadaha Xirfadlaha ah ee S45c E355 Gr 20 Pipe Steel Mo40 Honed Tube iyo Dhuumaha, Iyadoo loo marayo shaqadayada adag, waxaan had iyo jeer ku jirnay safka hore ee wax soo saarka tignoolajiyada nadiifka ah.Waxaan nahay lammaane cagaaran oo aad isku hallayn karto.Nala soo xidhiidh maanta wixii macluumaad dheeraad ah!
Laga soo bilaabo dhowrkii sano ee la soo dhaafay, shirkadeena waxay nuugtay oo u dheefshiiday tignoolajiyada casriga ah si isku mid ah gudaha iyo dibaddaba.Dhanka kale, ururkayagu wuxuu ka shaqeeyaa koox khubaro ah oo u heellan koritaankaChina Gr 20 Dhuumaha birta ah ee aan xumi lahayn iyo S45c E355 tuubada, Si loo daboolo baahida sii kordheysa ee macaamiisha guriga iyo korkeedaba, waxaan sii wadi doonaa horumarinta ruuxa ganacsi ee "Tayada, Hal-abuurka, Hufnaanta iyo Credit" waxaanan ku dadaali doonnaa inaan sare u qaadno isbeddellada hadda jira oo aan horseedno moodada.Waxaan si diiran kuugu soo dhaweyneynaa inaad soo booqato shirkadeena oo aad sameyso iskaashi.
Tuubooyinka makaanikada waxaa loo adeegsadaa codsiyada qaab dhismeedka farsamada iyo iftiinka.
Tuubooyinka makaanikada waxaa loo soo saaray si ay u buuxiyaan shuruudaha isticmaalka dhamaadka gaarka ah, qeexitaannada, dulqaadka iyo sifooyinka kiimikada.
Tuubooyinka farsamada iyo qaab dhismeedka iftiinka.Tani waxay u oggolaaneysaa isku mid ahaanshaha guryaha oo dhan tuubada oo dhan marka la barbar dhigo tuubooyinka ama tuubooyinka caadiga ah.Tuubooyinka makaanikada waxaa loo soo saari karaa qeexitaannada caadiga ah marka loo baahdo, laakiin badanaa waxaa loo soo saaraa waxqabadka "caadiga ah", iyada oo diiradda koowaad la saarayo xoogga dhalidda ee cabbirka saxda ah iyo dhumucda derbiga.Qaar ka mid ah codsiyada aadka loo sameeyay, xoogga wax-soo-saarka ayaa laga yaabaa inaan xitaa la cayimin, iyo soo saarista tuubooyinka farsamada "ku habboon isticmaalka".Tuubooyinka makaanikada waxaa ku jira codsiyo qaab dhismeed iyo mid aan dhisneyn oo ballaaran.
Waxaan u adeegsanaa khibradeena birta iyo wax soo saarka si aan u soo saarno alaabada tuubada farsamada ee aan fiicnayn si aan u daboolno baahiyahaaga.
Tan waxaa ka mid ah kaarboon, alloys iyo xitaa darajooyinka birta caadiga ah;la jeexjeexay, la caadiyeeyay oo la xanaaqay;culayska la yareeyey oo aan diiqada lahayn;oo damiyey oo xanaaqsan.
Dhuumaha birta ee mashiinada iyo baabuurta, ee loo isticmaalo samaynta iyo habaynta tubbada jirridda baabuurta iyo tubooyinka dabada, qalabka saxda ah, qalabka iyo qalabka.
Qaabka baabuurka iyo tuubada dabada
Soo-saarka iyo habaynta qalabka saxda ah, qalabka iyo qalabka.
Shuruudaha keenista: GBK, BKS, BK, BKW, NBK.
Hubi oo tijaabi:Halabuurka kiimikada, sifooyinka farsamada, muuqaalka iyo tijaabinta cabbirka, tijaabinta aan burburin, baaritaanka cabbirka walxaha.
Daaweynta dusha sare:Saliid galinta, faashash, toogashada.

Alaabooyinka tubbada ee khaaska ah ee isku xidhka tuubooyinka waxay ku bilaabmaan birta tayada ugu sareysa.Darajada, falanqaynta kiimikada iyo xaaladda dusha si taxadar leh ayaa loo tixgaliyaa, iyo hababka wax soo saarka ayaa loo habeeyey si loo gaaro tubbada ugu fiican ee isticmaalka dhamaadka.
Habayntu waxay ka samaysan tahay tuubo wareeg ah iyadoo lagu sawirayo qabow.Tuubada waxaa lagu sawiraa mander qaabaysan ama iyada oo loo sii marayo dhinta qaabaysan, ama labadaba.Dulqaadyada la wanaajiyay, dhammaynta iyo natiijadii sifooyinka farsamada.
Tuubooyinka aan xidhnayn iyo alxanka ee codsiyada farsamada iyo injineernimada guud.Tubooyinka dhismaha iyo ujeedooyinka qaabdhismeedka sida dhismayaasha madaniga ah, aasaaska, iwm.
