Chii chinonzi Pipe?

Pipe ichubhu ine hollow ine round cross chikamu chekufambisa kwezvinhu. Zvigadzirwa izvi zvinosanganisira zvinwiwa, gasi, pellets, hupfu nezvimwe. Izwi pombi rinoshandiswa richisiyaniswa kubva kuchubhu kuti rishande kune tubular zvigadzirwa zvehukuru hunowanzo shandiswa pombi uye pombi masisitimu. Pane ino webhusaiti, mapaipi anoenderana nedimensional zvinodiwa zve:ASME B36.10Welded uye Seamless Yakagadzirwa Simbi Pipe uyeASME B36.19Stainless Steel Pipe ichakurukurwa.

Pipe kana Tube?

Munyika yepombi, mazwi pombi uye chubhu achashandiswa. Pipe inowanzozivikanwa ne "Nominal Pipe Size" (NPS), ine madziro ukobvu kunotsanangurwa ne "Nhamba yehurongwa" (SCH).

Tube inogara ichitsanangurwa nedhayamita yayo yekunze (OD) uye ukobvu hwemadziro (WT), inoratidzirwa kungave muBirmingham waya gage (BWG) kana muzviuru zve inch.

Pipe: NPS 1/2-SCH 40 inotosvika kunze kwedhayamita 21,3 mm nemadziro akakora 2,77 mm.
Tube: 1/2 ″ x 1,5 inotosvika kunze kwedhayamita 12,7 mm nemadziro akakora 1,5 mm.

Iwo mashandisirwo makuru echubhu ari muHeat Exchangers, mitsara yezviridzwa uye madiki ekubatanidza pamidziyo yakaita sema compressors, boilers nezvimwe.

Zvishandiso zvePipe

Makambani einjiniya ane mainjiniya emidziyo kuona zvinhu zvichashandiswa mumapombi masisitimu. Yakawanda pombi ndeye kabhoni simbi (zvichienderana nebasa) inogadzirwa kune akasiyana ASTM zviyero.

Carbon-simbi pombi yakasimba, ductile, weldable, machinable, zvine musoro, yakasimba uye inogara yakachipa kupfuura pombi yakagadzirwa kubva kune zvimwe zvinhu. Kana kabhoni-simbi pombi inogona kusangana nezvinodiwa zvekumanikidza, tembiricha, marara kuramba uye hutsanana, isarudzo yechisikigo.

Simbi pombi inogadzirwa kubva kukanda-simbi uye ductile-iron. Iyo inonyanya kushandiswa ndeyemvura, gasi uye mitsetse yetsvina.

Pombi yepurasitiki inogona kushandiswa kufambisa zvinwiwa zvinoparadza, uye inonyanya kukosha pakubata magasi anoparadza kana ane ngozi uye kunyungudutsa mamineral acids.

Mamwe Masimbi uye Alloys pombi yakagadzirwa nemhangura, lead, nickel, ndarira, aruminiyamu uye akasiyana simbi asina tsvina anogona kuwanikwa nyore. Zvishandiso izvi zvinodhura uye zvinosarudzwa kazhinji nekuda kwekusagadzikana kwavo kwegora kune kemikari yemaitiro, Kutamisa Kupisa kwakanaka, kana nekuda kwesimba ravo rekusimba pakupisa kwakanyanya. Mhangura nemhangura alloys ndeyechinyakare kune mitsara yezviridzwa, kugadzira chikafu uye Heat Transfer michina. Masimbi asina tsvina ari kuwedzera kushandiswa kune izvi.

Lined Pipe

Zvimwe zvinhu zvinotsanangurwa pamusoro apa, zvakabatanidzwa kuti zvigadzire mapombi ane mitsetse.
Semuenzaniso, kabhoni simbi pombi inogona kuvharirwa mukati nezvinhu zvinokwanisa kutsungirira kurwiswa kwemakemikari inobvumira kushandiswa kwayo kutakura zvinwiwa zvinoparadza. Linings (Teflon®, semuenzaniso) inogona kuiswa mushure mekugadzira pombi, saka zvinokwanisika kugadzira spools yese yepombi isati yaiswa.

Zvimwe zvikamu zvemukati zvinogona kuva: girazi, mapurasitiki akasiyana-siyana, konkrete nezvimwewo, uyewo zvipfeko, seEpoxy, Bituminous Asphalt, Zink nezvimwe zvinogona kubatsira kuchengetedza pombi yemukati.

Zvinhu zvakawanda zvakakosha pakusarudza chinhu chakakodzera. Chinonyanya kukosha pane izvi idzvinyiriro, tembiricha, rudzi rwechigadzirwa, zviyero, mari nezvimwe.
