Uluhlu lwethu loNikezo

Ukususela ekusekweni kwayo ngo-2014,Intsimbi yeBotopuye waba ngumthengisi ohamba phambili we-carbon steel pipe eMntla China, owaziwa ngenkonzo ebalaseleyo, iimveliso ezikumgangatho ophezulu, kunye nezisombululo ezibanzi.

Inkampani inikezela ngeendidi zemibhobho ye-carbon steel kunye nemveliso ehambelana nayo, kubandakanywa i-seamless, i-ERW, i-LSAW, kunye ne-SSAW ipayipi yensimbi, kunye nomgca opheleleyo wokufakelwa kwemibhobho kunye neeflange.Iimveliso zayo ezikhethekileyo zikwabandakanya i-alloys ephezulu kunye ne-austenitic stainless steels, elungiselelwe ukuhlangabezana neemfuno zeeprojekthi ezahlukeneyo zepayipi.

Inkqubo yokuVelisa

Imibhobho yentsimbi ye-ASTM A53 inokuthi ingabinamthungo okanye idityaniswe.

Indlela yokuvelisa engenamthungo (Uhlobo S) kukusebenza okushushu kwentsimbi kwaye, ukuba kuyimfuneko, ukugqitywa okubandayo kwemveliso ye-tubular esebenza ngokushushu ukufezekisa imilo efunekayo, imilinganiselo kunye neempawu.

Bend Test

Ye-DN ≤ 50 [NPS ≤ 2], ubude obaneleyo bombhobho buya kukwazi ukugoba kubanda nge-90 ° malunga ne-cylindrical mandrel, ububanzi bayo buphindwe kalishumi elinesibini kwi-diameter yangaphandle yombhobho, ngaphandle kokuphuhlisa iintanda nakweyiphi na indawo.

Iphinda-phinda-yomelele ngakumbi(XXS) umbhobho phezu kwe-DN 32 [NPS 1 1/4] akufuneki ukuba ifakwe kuvavanyo lokugoba.

Uvavanyo lokucaba

Iityhubhu zentsimbi ezingenamthungo akufuneki ukuba zibe phantsi kovavanyo lokucaba.

Ukuba ifunwa yinkontileka, uvavanyo lunokwenziwa ngokwenkqubo kwi-S1.

Uvavanyo lweHydrostatic

Zonke iisayizi zemibhobho yentsimbi engenamthungo iya kugcina ixabiso elithile loxinzelelo lwamanzi ngaphandle kokuvuza ubuncinane imizuzwana emi-5.

Uxinzelelo lovavanyo lwemibhobho yentsimbi engapheliyo inokufumaneka kwiThebhile X2.2.

Uxinzelelo lovavanyo lwemibhobho yentsimbi ephothiweyo kunye nedityanisiweyo inokufumaneka kwiTheyibhile X2.3.

Uvavanyo loMbane olungonakaliyo

Ingasetyenziswa njengenye indlela yovavanyo lwe-hydrostatic.

Ubude bonke bombhobho ngamnye ongenamthungo buya kufakwa kuvavanyo lombane olungonakaliyo ngokuhambelana neE213, E309, okanyeE570.

Ukwaleka komphezulu

Umgangatho we-ASTM A53 uchaza iimfuno zemeko yombhobho omnyama kunye nokufakwa okushushu kwe-galvanized coating yeemibhobho zentsimbi.

Umbhobho omnyama

Umbhobho omnyama ubhekisela kubume bombhobho wensimbi ngaphandle konyango olungaphezulu.

Iibhobho ezimnyama zihlala zisetyenziselwa kwiindawo apho ixesha lokugcina lifutshane, indawo engqongileyo yomile kwaye ayinayo i-corrosion, kwaye ixabiso ngokuqhelekileyo liphantsi ngenxa yokuba akukho ngubo.

I-Hot-dip ye-Galvanized Coating

Imibhobho eyenziwe ngegalvanized, ekwaziwa njengemibhobho emhlophe, ihlala isetyenziswa kwindawo ezifumileyo okanye ezidlekayo.

I-zinc kwi-coating ye-zinc ingaba nayiphi na ibakala le-zinc kwi-ASTM B6.

Umbhobho wegalvanized uya kukhululeka kwiindawo ezingagqunywanga, amadyungudyungu, iidiphozithi eziqukuqelayo, kunye nokufakwa kwenkunkuma emdaka.Amaqhuma, uqikelelo, iiglobhu, okanye iidiphozithi ezinzima ze-zinc eziya kuphazamisana nokusetyenziswa okucetyiweyo kwezixhobo aziyi kuvunyelwa.

Umxholo weZinc ungekho ngaphantsi kwe-0.55 kg/m² [1.8 oz/ft²].

Ezinye iiCoatings

Ukongeza kumbhobho omnyama kunye nokufakwa kwe-galvanized, iintlobo zokugqoka eziqhelekileyo ziqukaipeyinti, 3LPE, FBE, njl. Uhlobo olufanelekileyo lokugquma lunokukhethwa ngokweemfuno ezithile zendawo yokusebenza.
