Ukuqonda i-ASTM A139: Umqolo we-SAWH Pipe kunye ne-Spiral Welded Pipe Application

Ehlabathini lemibhobho yoshishino, iikhowudi kunye nemigangatho elawula izinto ezisetyenzisiweyo zibalulekile ekuqinisekiseni ukhuseleko, ukuqina kunye nokusebenza. Omnye wale migangatho nguI-ASTM A139, edlala indima ebalulekileyo kwimveliso kunye nokusetyenziswa kwe-SAWH (i-spiral arc welded hollow) imibhobho kunye nemibhobho edityanisiweyo e-spiral. Kule bhulogi, siza kuxubusha ngokubaluleka kwe-ASTM A139, iimpawu zepayipi ye-SAWH, kunye neenzuzo ze-Helical Welded Pipe kumashishini ahlukeneyo.

Yintoni i-ASTM A139?

I-ASTM A139 yinkcazo ephuhliswe yi-American Society for Testing and Materials (ASTM) echaza iimfuno ze-electrofusion (arc) umbhobho wentsimbi odityanisiweyo. Lo mgangatho usebenza ngokukodwa kwimibhobho esetyenziselwa ukuthutha ulwelo kunye neegesi. Inkcazo ihlanganisa uluhlu olubanzi lwamabakala ensimbi kwaye iqinisekisa ukuba imibhobho eveliswayo idibana neempawu ezithile zomatshini kunye nokuqulunqwa kweekhemikhali.

Umgangatho we-ASTM A139 ubalulekile kubavelisi kunye neenjineli kuba inika isikhokelo kwinkqubo yokuvelisa, kubandakanya ubuchule be-welding kunye nemilinganiselo yokulawula umgangatho ekufuneka ithathwe. Ngokuthobela le migangatho, abavelisi banokuqinisekisa ukuba iimveliso zabo zithembekile kwaye zifanelekile kwizicelo ezahlukeneyo, ukusuka ekuthuthweni kweoli kunye negesi ukuya kwizakhiwo zokwakha.

Indima yombhobho we-SAWH

Umbhobho we-SAWH okanye i-spiral arc welded umbhobho ongaphakathi luhlobo lombhobho odityanisiweyo owenziwe ngokudibanisa imicu yentsimbi ethe tyaba ibe sisilinda. Le ndlela yokuvelisa ivumela ukudalwa kwemibhobho yobubanzi obukhulu obunamandla kwaye bulula. Itekhnoloji ye-spiral welding esetyenziswa kwiimibhobho ye-SAWH inikeza iingenelo ezininzi, kuquka:

1. Ukusebenza kweendleko:Inkqubo yokuvelisa imibhobho ye-SAWH idla ngoqoqosho ngakumbi kuneendlela zendabuko, okwenza kube yinto ekhangayo kwiiprojekthi ezinkulu.

2. UKUGQIBELEKA:Umbhobho we-SAWH unokuveliswa ngobukhulu obuhlukeneyo kunye nobukhulu, okwenza ukuba ulungele uluhlu olubanzi lwezicelo, kubandakanywa ukuhanjiswa kwamanzi, iinkqubo zamanzi amdaka, kunye neengxenye zesakhiwo.

3. Amandla Ongeziweyo:Ukwakhiwa kwe-Spiral welded kunika amandla okongeziweyo kunye nokuchasana noxinzelelo lwangaphandle, okwenza umbhobho we-SAWH ulungele iimeko zoxinzelelo oluphezulu.

Izinto eziluncedo kwi-spiral welded pipe

Umbhobho odityanisiweyo we-Spiral lolunye uhlobo lombhobho odityanisiweyo oveliswe kusetyenziswa ubuchwepheshe bokuwelda okujikelezayo. Indlela ibandakanya ukusonga umcu wentsimbi malunga ne-mandrel kunye nokuwuwelda kwi-spiral eqhubekayo.Umbhobho weHelical Welded inikeza iingenelo ezininzi, kuquka:

1. Iimpawu zokuhamba eziphuculweyo:Umphezulu wangaphakathi ogudileyo we-Helical Welded Pipe unciphisa i-turbulence kwaye uphucula ukuhamba kwamanzi, okwenza kube yinto efanelekileyo kwi-oyile kunye ne-gas industry applications.

2. UBUNTU BUNCISIWE:Uyilo olujikelezayo luvumela iindonga ezinqabileyo ngaphandle kokunciphisa amandla, okwenza umbhobho ube lula kwaye kulula ukuwuphatha kunye nokuthutha.

3. Ubude obuSetyenzwayo:I-Helical Welded Pipe inokuveliswa ubude obude, ukunciphisa inani lamalungu afunekayo kumbhobho kunye nokunciphisa amathuba okuvuza.

Ukuququmbela

Isishwankathelo, i-ASTM A139 ngumgangatho ophambili wokuveliswa kombhobho we-SAWH kunye ne-spiral welded pipe, ukuqinisekisa ukuba la macandelo abalulekileyo ahlangabezana nemigangatho yokhuseleko oluyimfuneko kunye nokusebenza. Iimpawu ezizodwa ze-SAWH kunye ne-spiral welded pipe zibenza baxabiseke kumashishini ukusuka kulwakhiwo ukuya kumandla. Njengoko iteknoloji iqhubela phambili, ukubaluleka kokubambelela kwimigangatho emiselweyo efana ne-ASTM A139 kuya kukhula kuphela ukuqinisekisa ukuba iziseko zoncedo esithembele kuzo zihlala zikhuselekile kwaye zisebenza kakuhle. Nokuba uyinjineli, ikontraka, okanye umphathi weprojekthi, ukuqonda le migangatho kunye neenzuzo zezi ntlobo zemibhobho kubalulekile ukwenza izigqibo ezinolwazi kwiiprojekthi zakho.
