P235GH ST35.8 SA192 Carbon Steel Seamless Pipe / Boiler Tube

Kuwonetsa katundu

The makina katundu wa boiler chitoliro ndi ndondomeko yofunika kuonetsetsa ntchito yomaliza utumiki (makina katundu) zitsulo, zomwe zimadalira mankhwala zikuchokera ndi kutentha mankhwala dongosolo zitsulo.Muyeso wa chitoliro chachitsulo, malingana ndi zofunikira zosiyanasiyana zogwiritsira ntchito, zimatchula ntchito yothamanga (mphamvu yamakokedwe, mphamvu zokolola kapena zokolola, elongation), komanso zizindikiro za kuuma ndi kuuma, komanso kutentha kwakukulu ndi kutsika komwe kumafunidwa ndi ogwiritsa ntchito. .
① Kutentha kwa ntchito ya chitoliro cha boiler ndi pansi pa 350 ℃, ndipo chitoliro chanyumba chimapangidwa makamaka ndi 10 ndi 20 carbon junction chitsulo chitoliro chotentha kapena chitoliro chozizira.Mayiko akunja amagwiritsa ntchito P235GH, SA192, ST35.8,106B, 210A1,210C
② Chitoliro chokwera kwambiri cha boiler nthawi zambiri chimagwiritsidwa ntchito potentha kwambiri komanso kupanikizika kwambiri, chitoliro chotenthedwa ndi mpweya wotentha kwambiri ndi nthunzi wamadzi, makutidwe ndi okosijeni ndi dzimbiri zidzachitika.Chitoliro chachitsulo chofunikira chimakhala ndi mphamvu zolimba kwambiri, makutidwe ndi okosijeni ambiri komanso kukana dzimbiri, komanso kukhazikika kwa minofu.
Chitoliro cha boiler chimagwiritsidwa ntchito kwambiri popanga chitoliro chamadzi, chitoliro chamadzi otentha, chitoliro chamadzi otentha kwambiri, chitoliro cha nthunzi chotenthetsera kwambiri cha boiler yamoto, chitoliro chachikulu ndi chaching'ono chautsi ndi chitoliro cha njerwa, etc.

Njira yoyendera bwino ya chitoliro chachitsulo chosasunthika

1. Kusanthula kapangidwe ka mankhwala: njira yowunikira mankhwala, kusanthula zida (chida cha infrared CS, spectrometer yowerengera molunjika, zcP, etc.).
2. Kuwunika kwapamwamba kwa chitoliro chachitsulo: 100%
A. Ultrasonic kuzindikira UT:
B. ET: (electromagnetic induction)
C. MT ndi kuzindikira kutayikira:
Kuzindikira zolakwika zamaginito, koyenera kuzindikira zolakwika zapamtunda ndi pafupi ndi pamwamba pa zida za ferromagnetic.
D. Kuzindikira zolakwika za Electromagnetic ultrasonic:
Palibe kugwirizana sing'anga chofunika, amene angagwiritsidwe ntchito kutentha mkulu ndi liwiro, akhakula ndi youma chitsulo chitoliro pamwamba kuzindikira chilema.
E. mayeso olowera madzi:
Fluorescence, kupaka utoto, ndi kuzindikira zolakwika za chitoliro chachitsulo pamwamba.
3. Thupi ndi mankhwala ntchito kuyendera chitoliro zitsulo;
4. Njira yoyendera ntchito ya chitoliro chachitsulo:
① Mayeso athyathyathya: zitsanzo zozungulira zooneka ngati C (S / D & gt; 0.15) H = (1 + 2) S / (+ S / D)
L=40 ~ 100mm pa kutalika kwa chigawo cha deformation =0.07~0.08
② Kukoka mayeso: L = 15mm popanda crack ndi woyenerera
③ Mayeso okulitsa ndi kupindika: tepi yapamwamba ndi 30 °, 40 ° ndi 60 °
④ Mayeso opindika: amatha m'malo mwa kuyesa kosalala (kwa chitoliro chachikulu).
