Ukubambelela kwinkolelo "yokwenza iimpahla eziphezulu kuluhlu kunye nokwenza abahlobo nabantu abavela kuyo yonke indawo emhlabeni", sihlala sibeka umdla wabathengi kwindawo yokuqala.Ikhabhoni / ingxubevange Umbhobho Steel engenamthungo / Tube, China ASTM A519 20crmo 20cr ingenamthungo, Sibambelele kumgangatho obalaseleyo, amaxabiso akhuphisanayo kunye nonikezelo ngexesha kunye nenkonzo engcono, kwaye sinethemba lokunyaniseka lokuseka ubudlelwane obuhle bexesha elide kunye nentsebenziswano kunye namaqabane ethu amatsha kunye namadala asuka kwihlabathi jikelele. Wamkelekile ngokunyanisekileyo ukuba uzibandakanye nathi.
Isishwankathelo
Isicelo
Isetyenziswa ikakhulu kumatshini kwaye isetyenziselwa ukwenza iisilinda zerhasi.ibandakanya ikhabhoni kunye nentsimbi yensimbi engenamthungo, kwaye igquma zombini iityhubhu yoomatshini engenamthungo eshushu-egqityiweyo kunye netyhubhu yomatshini egqityiweyo engenamthungo ngokobukhulu ukuya kunye nokubandakanya i-12 3⁄4 ngaphakathi. (323.8 mm) ngaphandle kwedayamitha yeetyhubhu ezingqukuva ezinobunzima bodonga njengoko kufuneka.

Ukunyamezelwa kobungqingqwa beDonga akunakusetyenziswa kwiindonga ze-0.199 ngaphakathi (5.05 mm) nangaphantsi; qhagamshelana nomvelisi wokunyamezela eludongeni kwiisayizi zetyhubhu ezinjalo.
umlinganiselo obaluleke ngakumbi, emva koko iityhubhu esebenza ngokubanda kufuneka icaciswe ngaphakathi kwidayamitha kunye nobukhulu bodonga okanye ngaphandle kwedayamitha kunye nedayamitha yangaphakathi.
I-Right-Turned Mechanical Tubing-Ukwahluka kwidayamitha yangaphandle kunye nobukhulu bodonga abuyi kudlula ukunyamezela kwiThebhile. Itheyibhile igubungela ukunyamezela njengoko isetyenziswe kwidayamitha yangaphandle kunye nobukhulu bodonga kwaye isebenza kubukhulu obuchaziweyo.
I-Ground Mechanical Tubing—Ukwahluka kwi-diaam-eter yangaphandle akuyi kuba ngaphezu kokunyamezelana okukwiThebhile. Le mveliso idla ngokuveliswa kumbhobho obandayo.
Ubude—Iityhubhu zoomatshini ziqhele ukufakwa kubude belitye lokusila, 5 ft (1.5 m) nangaphezulu. Ubude obuqinisekileyo bokusika bubonelelwa xa buchazwe ngumthengi. Ukunyamezela ubude kuboniswe kwiThebhile.
Ukuthe tye-Ukunyamezela okuthe tye kwityhubhu engqukuva engenamthungo akusayi kudlula imali eboniswe kwiTheyibhile.
Imfuneko yoVavanyo
1.Uvavanyo lobunzima
Xa imida yokuqina ifuneka, umvelisi kuya kuboniswana naye. Ubulukhuni obuqhelekileyo zidweliswe kwiThebhile .Xa kucacisiwe, uvavanyo lobunzima luya kwenziwa kwi-1% yeetyhubhu.
2.Tension Tests
Xa iipropathi zokuqina zifuneka, kuya kuboniswana nomvelisi. Iipropathi eziqhelekileyo zokuqina kwamanye amabakala aqhelekileyo kunye neemeko zobushushu zidweliswe kwitheyibhile.
3.Uvavanyo olungonakalisiyo
Iindidi ezahlukeneyo zovavanyo lwe-ultrasonic okanye i-electromagnetic engasebenziyo ziyafumaneka. Uvavanyo oluza kusetyenziswa kunye nemida yokuhlola iya kusekwa ngumenzi kunye nesivumelwano somthengi.
4.Uvavanyo oluvuthayo
Xa kukho iimfuno ezikhethekileyo zokucoceka kwensimbi, iindlela zokuvavanya kunye nemida yokwamkelwa ziya kusekwa ngumenzi kunye nesivumelwano somthengi.
