Ukuguqula phakathi kwentambo yemethrikhi kanye nentambo ye-BSP kudinga ukucatshangelwa ngokucophelela kanye nokuhambisana nezimfuneko ezithile zohlelo lokusebenza, okuhlanganisa ukukhetha ama-adaptha alungile noma okokufaka. Ngokuqonda umehluko oyinhloko nokucabangela izinselele nezinkinga zokuhambisana, ukuguqulwa okuyimpumelelo kungafinyelelwa, kuqinisekiswe ukusebenza okuphelele nokusebenza kahle.

imibuzo ejwayelekile ukubuzwa

Q:  Yimuphi umehluko omkhulu phakathi kwentambo yemethrikhi nentambo ye-BSP?

IMP:  Umehluko omkhulu phakathi kwentambo yemethrikhi kanye nentambo ye-BSP usekuklameni kwawo kanye nezinhlelo zokulinganisa. Imicu yemethrikhi ilandela isistimu yokulinganisa imethrikhi, isebenzisa amamilimitha ukuthola ukuphakama kwentambo nobubanzi. Izintambo ze-BSP, ngakolunye uhlangothi, zisebenzisa isistimu yokulinganisa ye-British Standard Pipe, enentambo yokuphakama kukalwa ngemicu iyintshi ngayinye nobubanzi obukalwa ngamayintshi.

Umbuzo:  Ingabe intambo yemethrikhi ingasetshenziswa ngokushintshana nentambo ye-BSP?

A:  Imicu yemethrikhi nemicu ye-BSP azishintsheki ngenxa yezinhlelo zazo zokulinganisa ezihlukene nemiklamo. Imicu yemethrikhi inokuphakama kangconywana kanye ne-engeli yentambo ehlukile uma kuqhathaniswa nochungechunge lwe-BSP. Ukuzama ukushintshanisa kungase kubangele ukulingana okungafanele, ukuvuza, noma ukulimala kwezingxenye ezinentambo.

Q:  Ingabe zikhona izinhlangano zokumisa intambo yemethrikhi nentambo ye-BSP?

A:  Yebo, kukhona izinhlangano zokumisa kuzo zombili izintambo zemethrikhi kanye nentambo ye-BSP. I-International Organization for Standardization (ISO) ibeka amazinga ochungechunge lwemethrikhi, iqinisekisa ukuhambisana nokufana kuwo wonke amazwe. Ochungechungeni lwe-BSP, i-British Standards Institution (BSI) inesibopho sokusungula nokugcina amazinga.

Q:  Yiziphi izimboni ezisebenzisa kakhulu intambo yemethrikhi?

A:  Imicu yemethrikhi isetshenziswa kakhulu ezimbonini ezifana nezezimoto, zemishini, nezokukhiqiza. Zivame ukutholakala emazweni aseYurophu nase-Asia lapho uhlelo lwemethrikhi luwuhlelo lokulinganisa olujwayelekile. Izintambo zemethrikhi zinikeza ukuxhumana okunembayo nokuthembekile, okubenza bafanelekele izinhlelo zokusebenza ezihlukahlukene.

Q:  Ingabe zikhona izinzuzo zokusebenzisa intambo ye-BSP phezu kwentambo yemethrikhi?

A:  Imicu ye-BSP inezinzuzo ezinhlelweni ezithile. Zivame ukusetshenziswa ezinhlelweni zamapayipi nama-hydraulic, ikakhulukazi emazweni alandela uhlelo lokulinganisa lwaseBrithani. Imicu ye-BSP inomklamo we-taper, ovumela ukuvala okuqinile nokumelana kangcono nokuvuza uma kuqhathaniswa nemicu yemethrikhi.

Umbuzo:  Ingabe intambo yemethrikhi nentambo ye-BSP ingaguqulwa kalula?

IMP:  Ukuguqula phakathi kwentambo yemethrikhi nentambo ye-BSP kudinga ukucatshangelwa ngokucophelela futhi kungase kungenzeki kalula. Amasistimu okulinganisa ahlukene, ama-engeli entambo, nama-pitches enza ukuguqulwa okuqondile kube inselele. Kwezinye izimo, ama-adaptha noma okokufakwa okunezintambo ezihambisanayo kungase kusetshenziselwe ukuxhuma izingxenye ezinezinhlobo ezahlukene zentambo. Nokho, kunconywa ukusebenzisa uhlobo olufanele lwentambo ukuze usebenze kahle nokuphepha.
