Sihlala siva ngenkqubo ye-tubing, ityhubhu engubani, ityhubhu, isixhobo se-tubing, i-tubing ye-metring, i-winring fubrung, i-piubing ye-tiub, i-tubing ejijekileyo, njalo njalo. Ngamagama amaninzi, ngubani igama eliqhelekileyo? Makhe sichaze ngokucokisekileyo ityhubhu yentsimbi engenasitayile engezantsi.
Ukuqonda ukuba ityhubhu yentsimbi engenanto ibizwa njani kwaye ihlelwe, ingcinga yokuqala kunye neyona nto ididayo kukucacisa:ityhubhukunye nombhobho. Zombini ityhubhu kunye nombhobho zithetha umbhobho we-pipe ngesiNgesi, kwaye akukho guqulelo ihambelana neTshayina. Ke yintoni umahluko phakathi kwabo?
1. Okokuqala, iindlela zokumelwa zahlukile: Iityhubhu zimelwe kubungakanani bodwa, ngelixa iityhubhu zodonga zimelwe yi-NPS (ubukhulu be-pipel pipe) ye-picter.
I-2. Imigangatho eyahlukeneyo: Umgangatho wetyhubhu yi-A269 kunye ne-ASTM A213, ngelixa umgangatho wombhobho yi-A312.
3. Ukudilizwa okwahlukileyo: Uluhlu lokunyamezela kwetyhubhu luncinci kunelo lombhobho. Kwi-cinezelo yexinzelelo, ityhubhu inokuthi ibonakalise ngokuchanekileyo uxinzelelo (i-PSI), ngelixa umbhobho edla ngokumelwa luxinzelelo lwe-PN.
I-4. Amazwe ayahlukile: Ityhubhu ikwimeko ye-inneled, kwaye akukho mfuneko yokuba i-pipe, yiyo loo nto ityhubhu ingabhekisa ngokuthe ngqo, ngelixa umbhobho kufuneka anxibelelane ne-elbow.
5. Izicelo ezahlukileyo: ityhubhu ineenkcazo ezininzi, ngoko isetyenziswa kakhulu kwiinkqubo zesixhobo, ngelixa umbhobho embalwa kwaye uninzi lweenkqubo zendlela kunye nenkqubo yendlela.
Leliphi igama elingqinayo lesiTshayina "letyhubhu" kunye "nombhobho"? Siyakholelwa ukuba isengqiqweni kakhulu ukuhambelana "nenkqubo yombhobho" kunye "nombhobho wesixhobo" ngokulandelelana. Lo mthetho umahluko usekwe kwisicelo kwaye ukwangumahluko ophambili phakathi "kwetyhubhu" kunye "nombhobho".
Amanye amagama kulula ukwahlulahlula:
I-1. Ukusuka kwimbono yendlela yokwenza imibhobho ye-Welding ebizwa ngokuba yimibhobho ye-WelDed, ngelixa imibhobho eyenziwe ngokuguqulwa ngokuchanekileyo kunye nemizobo ebandayo ibizwa ngokuba yityhubhu yethungo. Ityhubhu engenamthungo kufuneka ihlelwe njengokuchaneka kwetyhubhu kunye netyhubhu yetyhuzula engenamthungo esekwe kwintshukumo yabo yokuchaneka kunye nendlela yokubanda yokwenza.
I-2. I-BA TUBE ibhekisa ekuthini ukuqaqanjelwa kwetyhubhu, i-EP Tube ibhekisa kwi-Tubrochemical ye-Tube, i-tube ye-acid ibhekisa ekususweni kwe-oxidey kwi-acid yokufumana i-tube ye-Acid emva kokuba i-tube iqhubekile, yindawo esisiseko ye Ityhubhu, kwaye ityhubhu yokuphumeza ibhekisa kunyango lwepoling yepoling womphezulu wetyhubhu.
3. Ngokuphatheni imibhobho ye-fluid kunye netyhubhu, ikakhulu zibizwa ngokuba zimi kwi-engile yokusebenzisa.
I-4. Ityhubhu ye-metric ihambelana netyhefu ye-tubing, kwaye ihleliwe phantsi kwesixhobo. Ityhubhu ye-tuby ityhubhu ene-Diameter kunye nobunzima beWall bungalinganiswa kumacandelo aqhekekileyo.
5. Umbhobho otyunjiweyo ngumphunga, kwaye umbhobho wombhobho otyunjiweyo unokufumaneka kwinkcazo eneenkcukacha ngengcinga yokuthengiswa kweHikelok.
I-Hikelok, umvelisi wobungcali beevalves zesixhobo kunye nezixhobo ezifanelekileyo.
Iinkcukacha ezi-odolo zoku-odola, nceda ujonge ukhethoiikhathalogukwiIwebhusayithi yaseHikelok. Ukuba unayo nayiphi na imibuzo yokukhetha, nceda uqhagamshelane ne-hipti's iiyure ezingama-24 kwi-Intanethi.
