Ngaba umbhobho wentsimbi yekhabhoni ngumbhobho wentsimbi odityanisiweyo?

Umbhobho wentsimbi yekhabhoni awukho umbhobho wentsimbi odityanisiweyo. Umbhobho wentsimbi yeCarbon ubhekisa kwizinto ezithile zombhobho wentsimbi yintsimbi yekhabhoni, ebhekisa kwintsimbi ye-iron-carbon alloy enomxholo wekhabhoni Wc ngaphantsi kwe-2.11%. Ukongeza kwikhabhoni, ngokuqhelekileyo iqulethe inani elincinci le-silicon, i-manganese, i-phosphorus, isulfure kunye nezinye izinto ezingcolileyo. kunye nezinye izinto ezishiyekileyo zilandelela. Ukongezelela, le mbhobho yensimbi ye-carbon inoluhlu olubanzi lwezicelo, ezisetyenziswa ikakhulu ekwakhiweni, iibhulorho, oololiwe, izithuthi, iinqanawa kunye namashishini ahlukeneyo okuvelisa oomatshini.

Imibhobho yentsimbi yekhabhoni inokohlulwa ibe yimibhobho yentsimbi yekhabhoni edityanisiweyo kunye nemibhobho yentsimbi engenamthungo ngokwenkqubo yokuvelisa.

Imibhobho yentsimbi edityanisiweyo yeCarbon inokohlulwa ibe ziindidi ezintathu: imibhobho yentsimbi edityanisiweyo ethe tye, i-arc edityanisiweyo yentsimbi, imibhobho yentsimbi edityanisiweyo, kunye nemibhobho yentsimbi ethe tye ethe tye ngokwendlela yokwenza umthungo wentsimbi.
Umbhobho odityanisiweyo we-Longitudinal: I-weld ikwindlela ethe tye, ngoko ibizwa ngokuba yi-straight seam welded pipe.
Umbhobho odityanisiweyo we-Spiral: Umthungo we weld ukwimilo engqukuva, ebizwa ngokuba yi-spiral welding.

Iindlela ezintathu ze-welding zineenzuzo zazo kunye nokungonakali, kwaye yiyiphi enye enokusetyenziswa kuxhomekeke kwiimfuno zoyilo. Umbhobho wensimbi odityanisiweyo wekhabhoni unokufakwa kwiindawo ezininzi, ezifana neeprojekthi zokubonelela ngamanzi kunye nokuhambisa amanzi, iiprojekthi zokupakisha, imibhobho yogutyulo, ukuhanjiswa kweoyile kunye negesi, iintsika zesakhiwo kunye nezinye iiprojekthi. Indlela yangoku ye-welding ye-carbon steel welded steel pipe i-welding ye-arc enecala eliphindwe kabini. Le ndlela ye-welding inokusebenza okuphezulu, umgangatho ophezulu we-weld kunye nomphezulu ogudileyo.

Indlela yokuvelisa umbhobho wentsimbi yeCarbon engenamthungo:

Imibhobho yentsimbi yekhabhoni engenamthungo yohlulwe ibe ziindidi ezimbini: imibhobho yentsimbi eshushu eqengqelekayo (ekhutshiweyo) engenamthungo kunye nemibhobho yentsimbi etsalwa ngokubanda (eqengqiwe) ngenxa yeenkqubo ezahlukeneyo zokwenza izinto. Iityhubhu ezibandayo (eziqengqelekayo) zihlulwe zibe ziindidi ezimbini: iibhubhu ezijikelezayo kunye neebhubhu ezikhethekileyo.

1. Umbhobho wentsimbi eshushu eqengqelekayo (ekhutshiweyo) wekhabhoni yentsimbi engenamthungo: umbhobho wetyhubhu engqukuva → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuqengqelekayo amathathu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa → ukususwa kwetyhubhu → ukusika (okanye ukunciphisa) → ukupholisa → ukolula → Uvavanyo loxinzelelo lwamanzi ( okanye ukufumanisa isiphene) → ukuphawula → ugcino

Izinto eziluhlaza zokugubungela umbhobho we-carbon steel seamless yi-tube billet ejikelezileyo, kunye ne-tube embryo ejikelezayo kufuneka inqunywe ngomatshini wokusika ukukhulisa iibhilidi ezinobude obumalunga nemitha eyi-1, kwaye ihanjiswe esithandweni ngebhanti yokuhambisa. I-billet yondliwa kwiziko ukutshisa, iqondo lobushushu limalunga ne-1200 degrees Celsius. Amafutha yihydrogen okanye iacetylene. Ulawulo lobushushu kwisithando somlilo ngumba ophambili. Emva kokuba ityhubhu ejikelezayo iphumile kwisithando somlilo, kufuneka ihlatywe nge-piercer pressure. Ngokubanzi, oyena mgqobhozi uxhaphakileyo ngumgqobhozo we-cone roll. Olu hlobo lokugqobhoza lunemveliso ephezulu, umgangatho olungileyo wemveliso, ukwandiswa kwedayamitha ye-perforation enkulu, kwaye unokunxiba iindidi zentsimbi. Emva kokubhoboza, i-tube billet ejikelezayo inqunyulwa ngokulandelelana, iqhubekile okanye ikhutshwe yimiqulu emithathu. Emva kwe-extrusion, ityhubhu kufuneka ikhutshwe ukuze ilinganiswe. Ubukhulu ngesantya esiphezulu se-rotary cone gqobhoza imingxuma kwibillet ukwenza ityhubhu. Ububanzi bangaphakathi bombhobho wensimbi buchongwa ngobude bobubanzi bangaphandle be-drill bit yomatshini wokulinganisa. Emva kokuba umbhobho wensimbi ulinganisiwe, ungena kwinqaba yokupholisa kwaye upholiswe ngokutshiza amanzi. Emva kokuba umbhobho wensimbi upholile, uya kulungiswa. Emva kokulungiswa, umbhobho wensimbi uthunyelwa kwi-metal flaw detector (okanye uvavanyo lwe-hydraulic) ngebhanti yokuhambisa ukukhangela impazamo yangaphakathi. Ukuba kukho ukuqhekeka, iibhubhu kunye nezinye iingxaki ngaphakathi kombhobho wensimbi, ziya kufunyanwa. Emva kokuhlolwa komgangatho wemibhobho yentsimbi, ukhetho olungqongqo lwencwadi luyafuneka. Emva kokuhlolwa komgangatho wombhobho wensimbi, penda inombolo ye-serial, inkcazo, inombolo yebhetshi yokuvelisa, njl. Kwaye yakhweliswa kwindawo yokugcina impahla ngecrane.

2. Umbhobho wentsimbi epholileyo ozotyiweyo (eqengqelekayo) wekhabhoni yentsimbi engenamthungo: ityhubhu engqukuva blank→ukufudumeza→ukugqobhoza→isihloko→uchoko→ukuchola→ukufaka ioyile (icwecwe lobhedu)→umzobo obandayo ohamba ngeendlela ezininzi (ukuqengqeleka okubandayo)→ityhubhu engenanto→unyango lobushushu→Ukuqondisa →uvavanyo lwe-hydrostatic (ukubona iziphene)→ukuphawula→ugcino
