I-Victaulic ingumkhiqizi ohamba phambili emhlabeni wezinhlelo zokuxhuma amapayipi ngomshini. Uchungechunge lwayo lwe-Vic-300 MasterSeal™ butterfly valve-761 kanye nochungechunge lwe-Vic-Check® check valve-716 kanye no-716H lugunyazwe isitifiketi sohlobo lwe-DNV (Det Norske Veritas).
Isitifiketi sokugunyazwa sisebenza kuze kube uJuni 2017 futhi sihlanganisa amapayipi amapayipi e-Class III asetshenziselwa ukupholisa amanzi ahlanzekile, ukubuyiswa kwe-condensate, amasistimu angabalulekile, amapayipi okukhipha amanzi ahlanzekile nomoya wesevisi ongabalulekile.
I-Vic-300 MasterSeal butterfly valve isidlulile isitifiketi sohlobo lwe-DNV, ububanzi bosayizi ngu-DN50 – 300 (2” – 12”), ukucindezela okulinganiselwe kungu-21 bar (300 psi), izinga lokushisa ngu-0 – 121°C (32 – 250°) F) .
Umzimba we-valve ye-Vic-300 kanye ne-disc zenziwe nge-ductile iron ehambelana ne-ASTM A-536, futhi i-disc ine-electroless nickel coating ehambisana ne-ASTM B-773. Ungakhetha i-EPDM, i-nitrile rubber noma isihlalo senjoloba esiyi-fluorine. Idizayinelwe amajoyinti ama-grooved, ingasetshenziswa ne-Vic-Flange Adapter Type 741.
Uma kuqhathaniswa namavalvu amaningi endabuko, lawa mavalvu ahlinzeka ngokugeleza okungcono nokusebenza kangcono kokuvala kanye neminyaka yokuphila ende. Idizayini eyingqayizivele yediski ye-offset kanye nesiqu seziqephu ezimbili kungakhuphula izinga lokugeleza futhi kunciphise ithoshi yokusebenza kuze kufike ku-35%, futhi kunikeze uphawu lwebhamuza le-360-degree. Isihlalo senjoloba esithuthukisiwe sokucindezela kumzimba we-valve sivala ngokulinganayo ezinhlangothini zombili ze-valve, kunciphisa ukuguga kwesikhathi eside futhi kwandise impilo yesevisi.
Ngaphezu kwalokho, ama-valve e-MasterSeal kulula ukuwafaka nokuyinakekela ngenxa yokuthi alula futhi indawo yawo kunethiwekhi yamapayipi angashintshwa ngokungenamkhawulo. Amavalvu okugcina e-flange asindayo kakhulu futhi angakhomba kuphela endaweni elandelayo etholakalayo yembobo yebhawodi lapho kuqondaniswa i-lever noma i-opharetha yegiya. Lezi zici zenza ama-valve e-MasterSeal abe yisinqumo esicacile nesilula kubanikazi bemikhumbi, abaqhubi kanye nabasebenzi babo.
Ukugunyazwa kohlobo lwe-DNV yamavalvu okuhlola kuhlanganisa uchungechunge lwe-716H ngosayizi webanga le-DN50-DN80 (2”-3”), ingcindezi elinganiselwe ye-25 bar (365 psi) kanye nobubanzi besayizi DN100-DN 300 (4”) ngochungechunge lwe-716 Product – 12”) Isilinganiso sokucindezela amabha angama-21 (300 psi). Izinga lokushisa lincike ezintweni ezikhethiwe zokuvala.
I-valve yokuhlola yenziwe nge-ductile iron ehambisana ne-ASTM A-536 noma i-ASTM A-395. I-EPDM, irabha ye-nitrile noma izigxivizo zenjoloba e-fluorine zingakhethwa ukuze kuhlanganiswe amandla okucindezela okuphezulu nokusebenza kokwehla kokucindezela okuphansi. Idizayini yokuphela eyi-grooved ivumela ukuxhumana okusheshayo nokulula kusetshenziswa ukufakwa kwe-Victaulic noma ukufakwa kwesitayela se-Vic-Flange 741.
Imikhiqizo namasevisi achazwe kulokhu kukhululwa kwabezindaba akugunyazwanga isikhulu sasolwandle.
Imboni yezokwakha imikhumbi yomhlaba wonke iyahlomula ekubuyiseleni kabusha okuqinile kwama-oda okwakhiwa kwemikhumbi embonini yemikhumbi ngo-2021. Ngokusho kwedatha yezinyanga eziyisithupha evela enkampanini yocwaningo lwemakethe i-Clarkson Research Service, kusukela ngo-June, ama-oda womhlaba wonke abesezingeni eliphakeme leminyaka eyisikhombisa ngoJanuwari. 30, 2021. Kokubili izikhungo zemikhumbi zase-China nezaseNingizimu Korea zibike ukukhula okuqinile kwama-oda kulo nyaka. Ezinyangeni eziyisithupha zokuqala zalo nyaka, la mazwe amabili asengabakhiqizi abakhulu bemikhumbi, ikakhulukazi abalingisa ngamakhonsathi. Ngalesi sikhathi…
Umqhubi wetheminali waseJalimane u-Hamburger Hafen und Logistik AG (HHLA) wethule umqondo omusha wesistimu yezimpahla zamabhokisi esekelwe ku-Hyperloop. Uhlelo olusha lwathuthukiswa ngokubambisana nenkampani yokuqala i-Hyperloop Transportation Technologies (HyperloopTT) futhi yakhelwe ukuhamba phakathi kwamachweba nezindawo eziya phakathi nezwe ngesivinini sezindiza, ngaphandle kwesidingo sezindiza. Ngokusho kwe-HyperloopTT, umklamo ungahambisa iziqukathi eziyi-2,800 ngosuku (isigidi esingu-1 ngonyaka) ohlelweni lomugqa owodwa. Amaphilisi ayo “HyperPort” amise okwe-pod azovalwa…
Ngemva kwemibiko eminingi yamanani entengo yenkontileka yesikhathi eside ekhuphuka ngokushesha ukuze aqophe amazinga, kungase kube nezimpawu ezithile zokunciphisa ukukhula-kodwa akukho ukukhululeka komphakathi wabathumeli abanenkinga yezimali. I-Market intelligence platform i-Xeneta ibike ukuthi izinga lokukhula kwayo lehlile ngokwenkomba yayo yesikhathi eside ye-XSI yomphakathi. Ngokwemininingwane ye-Xeneta, ngo-2021, isilinganiso senkontileka yesikhathi eside sempahla yolwandle izokhuphuka ngaphezu kwama-37%, futhi…
U-Salvors uphakamise futhi wahlakaza ingxenye yesihlanu ye-roll-on ray yegolide eyayivaleleke e-St. Simmons Bay, Georgia ngoSepthemba 2019. Ngokufika kwesizini yeziphepho ka-2021, kukhona okunye ukusikeka okubili nezinye izingxenye ezintathu okudingeka kwenziwe ngaphambi kokuthi iphrojekthi iqedwe. Lo msebenzi kulindeleke ukuthi uthathe izinyanga ezimbalwa. Ngesikhathi somkhankaso wokufukula, isikebhe esidonsa amanzi sasebenzisa iziqapha-mlilo ukugeza inzika yomkhumbi ocwile ukuze kwehle isisindo. le ngxenye…
