Inkqubo yokuVeliswa kweUmbhobho wentsimbi we-ASTM A252 LSAW:

I-Longitudinal Submerged-arc Welded (LSAW) Umbhobho wamkela iteknoloji ye-arc welding ephantsi kwamanzi, usebenzisa i-filler welding, i-particle yokukhusela i-flux engcwatywe i-arc.

I-LSAW sisishunqulelo sesiNgesi se-arc entywiliselweyo edityanisiweyo yentsimbi yomthungo ethe ngqo.Inkqubo yemveliso ye-arc edityanisiweyo yentsimbi yomthungo ibandakanya iteknoloji yokwenza i-JCOE, i-coil eyenza iteknoloji ye-arc welding ephantsi kunye ne-UOE yokwenza iteknoloji.

Inkqubo yokwenziwa koMbhobho weLongitudinal Submerged-arc Welded(LSAW) imi ngolu hlobo lulandelayo:

Ukukhangela ipleyiti yeUltrasonic → ukugoba komphetho → ukugoba kwangaphambili → ukwenza → ukuwelda kwangaphambili → i-welding yangaphakathi→ i-welding yangaphandle → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → Ukwandisa → uvavanyo lwe-hydraulic →l.I-Chamfering → Uhlolo lwe-Ultrasonic → Uhlolo lwe-X-reyi → uhlolo lwamasuntswana omagnetic ekupheleni kwetyhubhu

Ukumila kweMichiza:

Intsimbi ayiyi kuba ngaphezu kwe-0.050 % ye-phosphorus.

Oomatshini kunye novavanyo lwe-NDT lweUmbhobho wentsimbi we-ASTM A252 LSAW:

Uvavanyo lwe-NDT (RT).

Uvavanyo lweHydrostatic

Uvavanyo loomatshini

Ukugoba uvavanyo-ubude obaneleyo bombhobho buya kuma bugobe bubanda nge-90 ° malunga ne-cylindrical mandrel.

Uvavanyo lokucaba-Nangona uvavanyo lungafuneki, umbhobho uya kuba nakho ukuhlangabezana neemfuno zovavanyo lokuthambisa.

Uvavanyo lwe-Hydrostatic-ngaphandle kokuba kuvunyelwe, ubude bombhobho ngamnye buya kufakwa kuvavanyo lwe-hydro-static ngaphandle kokuvuza ngodonga lombhobho.

Uvavanyo lombane olungonakaliyo-njengenye indlela yovavanyo lwe-hydro-static, umzimba opheleleyo wombhobho ngamnye uya kuvavanywa ngovavanyo lombane olungonakaliyo.apho uvavanyo lombane olungonakalisiyo lwenziwayo, ubude buya kuphawulwa ngoonobumba”NDE”

Uvavanyo lwe-ultrasonic

Uviwo lwangoku lwe-eddy

Ukusetyenziswa kweUmbhobho wentsimbi we-ASTM A252 LSAW:

Umbhobho owenziwe phantsi kolu luhlu lwemibhobho yemibhobho apho i-cylinder yensimbi isebenza njengelungu elisisigxina eliphethe umthwalo, okanye njengeqokobhe ukwenza iimfumba zekhonkrithi ezifakwe kwindawo.

Ixabiso eliphantsi le-ASTM i-252 ye-Steel Pipe Pile

Ukunyamezela ububanzi bangaphandle, ubukhulu bodonga, ubude kunye nobunzima:

Ngaphandle Ububanzi	Idayamitha yangaphandle yeemfumba zemibhobho ayinakwahluka ngaphezu kwe-±1% ukusuka kwidayamitha yangaphandle echaziweyo.
Ubunzima bodonga	Ubunzima bodonga nakweyiphi na indawo abuyi kuba ngaphezu kwe-12.5% phantsi kobukhulu obuchaziweyo bodonga.
Ubude	Iimfumba zemibhobho ziya kunikezelwa ngobude obungakhethiyo obubodwa, ubude obuphindwe kabini, okanye ubude obufanayo njengoko kuchaziwe kumyalelo wokuthenga, ngokuhambelana nemida ilandelayo:	Single random ubude	16 ukuba 25ft (4.88 ukuba 7.62mm), intshi
		kabini ubude random	Ngaphezulu kwe-25ft (7.62m) kunye nomyinge omncinci we-35ft (10.67m)
		Ubude obufanayo	ubude njengoko kuchaziwe ngotshintsho oluvumelekileyo lwe ±1 ngo.
Ubunzima	Ubude bengqumba yombhobho nganye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bayo abuyi kwahluka ngaphezu kwe-15% ngaphezulu okanye i-5% phantsi kobunzima bethiyori, ibalwe kusetyenziswa ubude bayo kunye nobunzima bayo ngeyunithi yobude.
