Kodi STPG 370 Pipe Material ndi chiyani?

STPG 370 ndi chitoliro chachitsulo chochepa cha carbon chotchulidwa mu Japanese standard JIS G 3454.

STPG 370 ili ndi mphamvu yocheperako ya 370 MPa ndi mphamvu zokolola zochepa za 215 MPa.

STPG 370 imatha kupangidwa ngati machubu achitsulo opanda msoko kapena machubu achitsulo otsekemera pogwiritsa ntchito njira yowotcherera yamagetsi (RW).Ndi yoyenera kugwiritsidwa ntchito pamapaipi opopera omwe amatha kutentha mpaka 350 ° C.

Kenako, tiyang'ana STPG 370 kuchokera kuzinthu zopangira, kupanga mankhwala, makina, kuyesa kwa hydrostatic pressure, kuyesa kosawononga, ndi zokutira zamagalasi.

Ngati kuyang'ana kwa akupanga kukugwiritsidwa ntchito, kuyenera kukhazikitsidwa pamlingo wokhwima kuposa chizindikiro cha UD kalasi mu JIS G 0582.

Ngati kuyesa kwamakono kwa eddy kukugwiritsidwa ntchito, kuyenera kutengera muyeso womwe ndi wolimba kwambiri kuposa chizindikiro cha gulu la EY mu JIS G 0583.

Zokhala ndi malata

Mu JIS G 3454, mapaipi achitsulo osatsekedwa amatchedwamapaipi akudandipo mipope yachitsulo yamalata imatchedwamipope yoyera.
