Daim ntawv thov teb
B7 threaded tuav yog cov nyiam fastener rauhigh-kub, siab-siab thiab hnyav-load industrial scenarios, dav siv nyob rau hauv:
Petrochemical kev lag luam:
Flange kev sib txuas, cov hlab ntsha siab, cov khoom siv hluav taws xob sib txuas, cov kav dej roj / roj thiab cov khoom siv refinery fastening.
Kev tsim hluav taws xob:
Boiler systems, chav turbines, nuclear fais fab nroj tsuag auxiliary khoom, thermal hwj chim pipeline thiab valve txuas.
Lub tshuab hnyav:
Loj gearboxes, hydraulic xovxwm puag, cov khoom siv tsuas thiab steel zeb dov zeb structural fastenings.
Kev tsim kho & infrastructure:
High-nce lub tsev steel qauv nodes, choj bearing rooj thiab hnyav-cov dej num txhawb kev sib txuas.
Kev tsim khoom lag luam:
High- cov twj tso kua mis siab, li qub, lub qhov cub muaj thiab siab - cov khoom siv ua haujlwm kub tau ruaj khov.
Offshore engineering:
Offshore platform pipeline kev sib txuas thiab cov khoom siv hnyav marine fastening (nrog kev txhim kho los tiv thaiv- kev kho corrosion).
Kev siv ceev faj
Kev sib txuam Fasteners:
Tshwj xeeb khub nrogASTM A194 Qib 2H / 7 hnyav hex txiv ntseej(2H rau ambient kub, 7 rau siab- kub tsawg dua los yog sib npaug rau 538℃) thiab siab - lub zog tiaj tus ntxhua khaub ncaws; zam kev sib xyaw nrog cov tsis yog- qauv lossis qis- qib fasteners.
Torque Control:
Siv lub calibrated torque wrench kom nruj kom tsim torque; siv high-kub los tiv thaiv- txeeb cov roj nplua nyeem rau siab- cov ntawv siv cua sov los tiv thaiv xov seizing thiab galling.
Kev txwv kub:
Tsis txhob siv nyob rau hauv ib puag ncig tshaj 538℃(1000℃F); xaiv tshwj xeeb siab -kub threaded tuav rau siab dua qhov yuav tsum tau muaj.
Environmental Adaptation:
Xaiv qhov kev kho deg rau ib qho kev ua haujlwm-dub oxide / oiled rau sab hauv tsev qhuav ib puag ncig, HDG / Dacromet rau sab nraum zoov / ntub dej; zam kev siv ncaj qha rau hauv hiav txwv siab siab - chloride ib puag ncig yam tsis muaj kev tshwj xeeb los tiv thaiv - kev kho corrosion.
