BSP threads, ntawm qhov tod tes, siv British Standard Pipe ntsuas qhov system, nrog xov suab ntsuas hauv xov ib nti thiab txoj kab uas hla ntsuas hauv inches.

Q:  Cov metric xov puas tuaj yeem siv sib hloov nrog BSP xov?

A:  Metric threads thiab BSP threads tsis hloov pauv tau vim lawv qhov ntsuas sib txawv thiab cov qauv tsim. Metric threads muaj lub suab zoo dua thiab cov xov sib txawv piv rau BSP threads. Kev sim hloov lawv tuaj yeem ua rau tsis haum, xau, lossis puas tsuaj rau cov khoom sib txuas.

Q:  Puas muaj cov koom haum tsim qauv rau metric xov thiab BSP xov?

A:  Yog, muaj cov koom haum tsim qauv rau ob qho tib si metric xov thiab BSP xov. Lub koom haum International rau Standardization (ISO) tau teeb tsa cov qauv rau metric threads, kom ntseeg tau tias muaj kev sib raug zoo thiab kev sib haum xeeb thoob plaws lub tebchaws. Rau BSP threads, British Standards Institution (BSI) yog lub luag haujlwm los tsim thiab tswj cov qauv.

Q:  Cov kev lag luam twg feem ntau siv metric xov?

A:  Metric threads yog siv dav hauv kev lag luam xws li tsheb, tshuab, thiab kev tsim khoom. Lawv feem ntau pom nyob rau hauv cov teb chaws Europe thiab Esxias lub teb chaws uas cov metric system yog tus qauv ntsuas system. Metric threads muab cov kev sib raug zoo thiab txhim khu kev qha, ua rau lawv haum rau ntau yam kev siv.

Q:  Puas muaj qhov zoo ntawm kev siv BSP xov tshaj metric xov?

A:  BSP threads muaj qhov zoo hauv qee yam kev siv. Lawv feem ntau siv nyob rau hauv cov kav dej thiab hydraulic systems, tshwj xeeb tshaj yog nyob rau hauv lub teb chaws uas ua raws li lub British ntsuas system. BSP threads muaj ib tug taper tsim, uas tso cai rau ib tug nruj sealing thiab zoo dua tiv thaiv to los piv rau metric threads.

Q:  Cov metric xov thiab BSP xov puas tuaj yeem hloov pauv tau yooj yim?

A:  Kev hloov pauv ntawm metric xov thiab BSP xov yuav tsum tau ua tib zoo xav thiab tej zaum yuav tsis yooj yim ua tiav. Qhov sib txawv ntsuas tshuab, xov lub kaum sab xis, thiab pitches ua rau kev hloov pauv ncaj qha. Qee zaum, adapters lossis fittings nrog cov xov sib txuas yuav raug siv los txuas cov khoom sib txawv nrog ntau hom xov. Txawm li cas los xij, nws raug pom zoo kom siv cov xov zoo tsim nyog rau kev ua haujlwm zoo thiab kev nyab xeeb.
