Butt Weld Reducers for Connecting Pipes of Ibang Diameters

Butt weld reducers Ay mga tubo na may dalawang port ng iba't ibang diameter. Maaari silang gamitin upang magkakonekta ang mga tubo ng iba't ibang diameter sa pamamagitan ng welding, na nagbibigay ng makinis na paglipat para sa flow ng likido. Ito ay nagbabawas ng pagkawala ng paglaban at presyon, at tumutulong upang mapanatili ang epektibong operasyon ng sistema ng pipeline. Pinapayagan din ng mga reducers ng butt weld para sa flexible layout ng sistema ng pipeline sa limitadong espasyo, nagbibigay ng kaginhawahan para sa makinis na operasyon at pag-aayos ng layout.

Concentric butt weld reducer
Eccentric butt weld reducer

Ang mga conentric butt weld reducers ay ginagamit upang magkakonekta ng mga tubo ng iba't ibang diameters. Ang mga ito ay mga reducers na may gitnang axis na magkakasabay sa parehong dulo.
Ito ay konektado sa tubo sa pamamagitan ng welding, at may mataas na lakas at pagganap ng sealing, at maaaring makatiis ng mataas na presyon at temperatura.
Ito ay gawa ng stainless steel, duplex steel, o espesyal na alloy steel, at may mahusay na resistance ang corrosion, at maaaring labanan ang corrosion media tulad ng oksidasyon, acidity, alkalinity, at solusyon ng asin.

Ang mga eccentric butt weld reducers ay ginagamit upang magkakonekta ng mga tubo ng iba't ibang diameter, kung saan ang mga linya ng gitna ng axis ng dalawang dulo ay hindi magkakasabay.
Ito ay konektado sa tubo sa pamamagitan ng welding, na may mataas na lakas at pagganap ng sealing, at maaaring makatiis ng mataas na presyon at temperatura.
Ito ay ginawa ng stainless steel, duplex steel, o espesyal na alloy steel, na may corrosion resistance, at maaaring labanan ang corrosion media tulad ng oksidasyon, acidity, alkalinity, at solusyon ng asin.

Functions

Concentric butt weld reducers are used to connect two pipes with different diameters but coincident center axes.

Ang mga Concentric butt weld reducers ay nag-uugnay ng dalawang tubo sa iba't ibang diameter ngunit may magkakasabay na linya ng center axis, at angkop para sa mas maliit na sistema ng tubo ng diameter.

Eccentric butt weld reducers are used to connect two pipes with different diameters but non-coincident center axes

Ang Eccentric butt weld reducers ay ginagamit upang magkakonekta ng dalawang tubo sa iba't ibang diameter ngunit may mga axes na hindi coincident center, na nagpapahintulot para sa patayo at horizontal na offset ng mga tubo. Angkop ang mga ito para sa mga sitwasyon kung saan kailangang malutas ang patayo at horizontal na offset o kailangang maiwasan ang mga limitasyon sa espasyo.
