Codsiyada daboolka saliidda:

Loo isticmaalo qodista ceelka saliidda waxaa inta badan loo isticmaalaa in geeddi-socodka qodista iyo ka dib marka la dhammeeyo ee taageerada derbiga ceelka, si loo hubiyo in geeddi-socodka qodista iyo hawlgalka caadiga ah ee ceelka oo dhan ka dib markii la dhammeeyey.Due in xaaladaha kala duwan ee juquraafi, gobolka stress dhulka hoostiisa waa adag yahay, iyo tallaabo dhamaystiran ee tensile, compressive, foorarsan iyo torsional stress on shuruudaha kaska laftiisa ay sabab u tahay tayada tuubada. Sabab qaar ka mid ah, waxay u horseedi kartaa hoos u dhigista wax soo saarka ceelka oo dhan, ama xitaa qashinka.

Noocyada daboolka saliidda:

Sida laga soo xigtay SY/T6194-96 “kasarka batroolka”, waxa loo qaybin karaa laba nooc: dunta gaagaaban iyo dakadkeeda iyo daboolka dunta dheer iyo qoorteeda.

Heerka daboolka saliidda iyo baakadaha:

Sida laga soo xigtay SY/T6194-96, daboolka gurigu waa in lagu xidhaa silig bir ah ama suunka birta ah. Qaybta bannaan ee dabool kasta iyo dunta qoortu waa in lagu xidhaa giraan ilaalin ah si loo ilaaliyo dunta.

Daboolka waa in lagu bixiyaa dunta iyo kooraska sida waafaqsan API SPEC 5CT1988 daabacaadda kowaad ama mid kasta oo ka mid ah foomamka dhamaadka tuubada soo socota: dhammaadka siman, dunta wareegsan ee aan lahayn koolada ama kooraska, dunta trapezoidal oo leh ama la'aan, dun toosan, farsamaynta dhamaadka gaarka ah, dhismaha giraanta shaabadda.

Heerka birta ee daasadda batroolka:

Heerka birta daboolka saliidda waxaa loo qaybin karaa darajooyin bir oo kala duwan iyadoo loo eegayo xoogga birta lafteeda, kuwaas oo ah H-40, J-55, K-55, N-80, C-75, L-80, C-90, C-95, P-110, Q-125, iwm.Xaalado kala duwan oo ceelal ah, qoto dheer oo qoto dheer, isticmaalka darajada birta ayaa sidoo kale ka duwan. Qalabka laftiisa ayaa sidoo kale looga baahan yahay in uu noqdo mid u adkaysta deegaanka daxalka. Meelaha xaaladaha juqraafiyeed ee adag, daboolka ayaa sidoo kale looga baahan yahay inuu u adkaysto burburinta.

Habka xisaabinta miisaanka ee daboolka saliidda waa sida soo socota:

KG/ m = (dhexroorka dibadda - dhumucda gidaarka) * dhumucda gidaarka * 0.02466

Dhererka daboolka saliidda:

Waxaa jira saddex nooc oo dherer ah oo ay qeexday API: R-1 4.88 ilaa 7.62m, R-2 7.62 ilaa 10.36m, R-3 10.36m ilaa ka dheer.

Nooca xirmada daboolka batroolka:

API 5CTNoocyada daboolka batroolka waxaa ka mid ah STC (xajin wareega gaaban), LTC (xajin wareega dheer), BTC (xarunta jaranjarada qayb ka mid ah), VAM (bockle king) iyo noocyada kale ee xirmooyinka.

Kormeerka waxqabadka jirka ee daboolka batroolka:

(1) Sida laga soo xigtay SY/T6194-96. Si loo sameeyo tijaabada fidsan (GB246-97) test tensile test (GB228-87) iyo hydrostatic test.

(2) tijaabinta hydrostatic, tijaabada fidsan, sulfide stress cracking test, test hardness (ASTME18 or E10 latest version), test tensile test, transverse impact test (ASTMA370, ASTME23 iyo nooca ugu dambeeyay ee heerarka laxiriira) sida ku cad qodobada Machadka Batroolka Mareykanka APISPEC5CT198

Soo dejinta iyo dhoofinta saliidda:

(1) Wadamada ugu muhiimsan ee soo dejinta saliida waa: Germany, Japan, Romania, Czech Republic, Italy, United Kingdom, Austria, Switzerland, United States, Argentina, Singapore sidoo kale soo dejinta.Heerarka soo dejinta waxay tixraacaan heerka API5A ee Machadka Batroolka Mareykanka, 5AX, 5AC. Darajada Birta waa H-40, J-55, N-80, P-110, C-75, C-95 iyo wixii la mid ah 244.510.03R-2, 244.511.05r-2, iwm.

(2) Waxaa jira saddex nooc oo dherer ah oo ay qeexday API: R-1 waa 4.88 ~ 7.62m, R-2 waa 7.62 ~ 10.36m, R-3 waa 10.36m ilaa ka dheer.

(3) Qayb ka mid ah badeecooyinka la soo dejiyo waxaa lagu calaamadeeyay LTC, tusaale ahaan, gacan-xidhka fidiyaha.

(4) Marka lagu daro heerarka API, tiro yar oo baadiyaha ah oo laga keeno Japan waxay u hoggaansamaan heerarka warshadaha Japan (sida Nippon Steel, Sumitomo, Kawasaki, iwm.), nambarada birta waa NC-55E, NC-80E, NC-L80, NC-80HE, iwm.

(5) Kiisaska sheegashada, waxaa jiray cillado muuqaal ah sida baaldi madow, dhaawaca xadhigga siliga, isku laabma tuubada jirka, xidhidhka jaban iyo dunta fogaanta adag ee dulqaadka, isku dhafka qiimaha J ee dulqaadka, iyo dhibaatooyinka tayada gudaha sida dildilaaca jilicsan iyo xoogga dhalidda hoose ee daboolka.
