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

Kwihlabathi leepayipi zoshishino, iikhowudi kunye nemigangatho elawula izixhobo ezisetyenzisiweyo zibalulekile ekuqinisekiseni ukhuseleko, ukuqina kunye nokusebenza. Omnye wale migangatho nguloI-ASTM A139, edlala indima ebalulekileyo ekuvelisweni nasekusetyenzisweni kweepayipi ze-SAWH (spiral arc welded hollow) kunye neepayipi ze-spiral welded. Kule blog, siza kuxoxa ngokubaluleka kwe-ASTM A139, iimpawu zepayipi ye-SAWH, kunye neenzuzo zePipe ye-Helical Welded kwiimveliso ezahlukeneyo.

Yintoni i-ASTM A139?

I-ASTM A139 yinkcazo eyenziwe yi-American Society for Testing and Materials (ASTM) echaza iimfuno zombhobho wentsimbi odityanisiweyo nge-electrofusion (arc). Lo mgangatho usebenza ngokukodwa kwiipayipi ezisetyenziselwa ukuthutha ulwelo kunye neegesi. Le nkcazo igubungela uluhlu olubanzi lweeklasi zentsimbi kwaye iqinisekisa ukuba iipayipi eziveliswayo ziyahlangabezana neempawu ezithile zoomatshini kunye nokwakheka kweekhemikhali.

Umgangatho we-ASTM A139 ubalulekile kubavelisi nakwiinjineli kuba unika isikhokelo kwinkqubo yemveliso, kubandakanya iindlela zokuwelda kunye namanyathelo okulawula umgangatho ekufuneka athathwe. Ngokulandela le migangatho, abavelisi banokuqinisekisa ukuba iimveliso zabo zithembekile kwaye zifanelekile kwiintlobo ngeentlobo zezicelo, ukusuka ekuthuthweni kweoyile negesi ukuya ekusetyenzisweni kwezakhiwo.

Indima yombhobho we-SAWH

Umbhobho we-SAWH okanye umbhobho ongenanto odibeneyo we-spiral arc luhlobo lombhobho odibeneyo owenziwe ngokuhlanganisa imicu yesinyithi esithe tyaba ngendlela ye-spiral. Le ndlela yokuvelisa ivumela ukwenziwa kwemibhobho emikhulu enobubanzi obuqinileyo nobukhaphukhaphu. Itekhnoloji yokugubungela ejikelezayo esetyenziswa kwiImibhobho ye-SAWH Inika iingenelo ezininzi, kuquka:

1. Ukusebenza kakuhle kweendleko:Inkqubo yokuvelisa imibhobho ye-SAWH idla ngokuba yeyongayo kuneendlela zemveli, nto leyo eyenza ukuba ibe lukhetho olunomtsalane kwiiprojekthi ezinkulu.

2. UKUSEBENZISA OKUNINZI:Umbhobho we-SAWH unokwenziwa ngobukhulu obahlukeneyo nobukhulu, nto leyo eyenza ukuba ufaneleke kwiintlobo ngeentlobo zezicelo, kuquka amanzi, iinkqubo zamanzi amdaka, kunye nezinto zokwakha.

3. Amandla Aphuculweyo:Ulwakhiwo oludibeneyo olujikelezayo lunika amandla ongezelelweyo kunye nokumelana noxinzelelo lwangaphandle, nto leyo eyenza umbhobho we-SAWH ulungele iimeko zoxinzelelo oluphezulu.

Iingenelo zombhobho odibeneyo ojikelezayo

Umbhobho odibeneyo ojikelezayo lolunye uhlobo lombhobho odibeneyo owenziwe ngeteknoloji yokudibanisa ojikelezayo. Le ndlela ibandakanya ukusonga umcu wentsimbi ujikeleze i-mandrel uze uwudibanise ngendlela ejikelezayo eqhubekayo.Umbhobho we-Helical Welded Inika iingenelo ezininzi, kuquka:

1. Iimpawu zokuhamba kwamanzi eziphuculweyo:Umphezulu ongaphakathi ogudileyo weHelical Welded Pipe unciphisa ukuxinana kwaye uphucula ukuhamba kolwelo, nto leyo eyenza ukuba ilungele ukusetyenziswa kushishino lweoyile negesi.

2. Ubunzima buncitshisiwe:Uyilo olujikelezayo luvumela iindonga ezincinci ngaphandle kokuphazamisa amandla, nto leyo eyenza umbhobho ube lula kwaye kube lula ukuwuphatha nokuwuthutha.

3. Ubude obunokulungiselelwa ngokwezifiso:Umbhobho oWeldiweyo weHelical unokwenziwa ngobude obude, nto leyo enciphisa inani lamalungu afunekayo kumbhobho kwaye inciphise amathuba okuvuza.

Ukuququmbela

Ngamafutshane, i-ASTM A139 ngumgangatho obalulekileyo wokuveliswa kombhobho we-SAWH kunye nombhobho odibeneyo ojikelezayo, oqinisekisa ukuba ezi zinto zibalulekileyo ziyahlangabezana nemigangatho yokhuseleko kunye nokusebenza efunekayo. Iimpawu ezizodwa ze-SAWH kunye nombhobho odibeneyo ojikelezayo zizenza zibe luncedo kakhulu kumashishini aqala kulwakhiwo ukuya kumandla. Njengoko iteknoloji iqhubeka ihambela phambili, ukubaluleka kokunamathela kwimigangatho esele imiselwe njenge-ASTM A139 kuya kukhula kuphela ukuqinisekisa ukuba iziseko esixhomekeke kuzo zihlala zikhuselekile kwaye zisebenza kakuhle. Nokuba ungunjineli, umakhi, okanye umphathi weprojekthi, ukuqonda le migangatho kunye neenzuzo zezi ntlobo zemibhobho kubalulekile ekwenzeni izigqibo ezinolwazi kwiiprojekthi zakho.
