- Nws muaj zog compressive siab thiab kev tiv thaiv impact thiab tuaj yeem tiv tau lub siab thiab thauj khoom loj
- Siv dav hauv cov khoom siv hluav taws xob thiab kev tsim hluav taws xob, cov yeeb hlau seamless boiler yog cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob, thiab lawv qhov ua tau zoo cuam tshuam ncaj qha rau kev ua haujlwm thiab kev nyab xeeb ntawm hluav taws xob.
- Hauv kev lag luam petrochemical, lawv feem ntau siv los thauj cov roj thiab roj kub siab thiab siab, thiab lawv qhov ruaj khov thiab kev ntseeg siab heev.
- Cov yeeb hlau seamless boiler muaj kev tiv thaiv siab thiab corrosion zoo, thiab yog ib qho tseem ceeb ntawm kev siv dav hlau, kev tsim nkoj thiab lwm yam.
Carbon steel (SA-210 Gr. A1/A2, rau qhov siab nruab nrab thiab qis); Alloy steel (SA-213 T11/T22/T91, rau kub siab/siab); Stainless steel (304/316, rau cov chaw corrosive)
Kev Ua Khoom Chemical

Cov Khoom Mechanical
Lub Zog Tensile: Carbon steel ≥415 MPa; Alloy steel (T91) ≥585 MPa; Stainless steel ≥515 MPa
Lub Zog Yield: Carbon steel ≥255 MPa; Alloy steel (T91) ≥415 MPa; Stainless steel ≥205 MPa
Kev Ncua: ≥30% (tag nrho hom)
Kev Tiv Thaiv Kub thiab Corrosion
Carbon steel: ≤450°C, tiv thaiv oxidation me; Alloy steel (T91): txog 650°C, muaj kev tiv thaiv creep zoo; Stainless steel: txog 800°C, zoo heev hauv cov pa corrosive
Qhov Kub Ua Haujlwm
Kev Pab: -20°C txog 800°C (sib txawv raws li cov khoom); carbon steel txwv sab sauv 450°C (kev pheej hmoo oxidation); alloy/stainless steel rau cov seem kub siab tseem ceeb
Hom thiab Qhov Loj
Hom: Seamless (siab siab, superheaters); welded (siab qis, phab ntsa dej)
Txoj Kev Ncaws: 10mm-219mm (feem ntau: 38mm, 51mm, 63.5mm); Phab Ntsa Tuab: 2mm-20mm
Ntev: 3m-12m (tuaj yeem txiav raws li kev xav tau)
Kev Ua Raws Li Cov Qauv
ASTM (SA-178, SA-210, SA-213); ASME Section I (lub tshuab boiler hluav taws xob); DIN 17175 (European); JIS G3461 (Japanese industrial boilers)
Kev Tsim Kho
Seamless: Kub-rolled/extruded (tsis muaj vuam, siab siab); Welded: ERW/TIG (tus nqi qis rau cov chaw tsis tseem ceeb)
Tuaj yeem ua haujlwm (carbon/alloy steel yooj yim dua li stainless); Tuaj yeem tsim los ntawm khoov/flanging
Kev Siv Tseem Ceeb
Lub tshuab hluav taws xob: Superheaters, reheaters, phab ntsa dej, economizers
Lub tshuab boiler industrial: Cua sov hauv refineries, cov chaw tsim tshuaj
Marine: Cov tshuab pas dej nkoj (stainless/alloy rau kev tiv thaiv dej hiav txwv)
Kev Rov Qab Kub: Cov khoom siv hloov kub pa tawm
Cov Txiaj Ntsig Tseem Ceeb
Carbon steel: Tus nqi zoo rau siab nruab nrab-qis; Alloy steel: Lub zog siab ntawm qhov kub siab tshaj; Stainless steel: Tiv thaiv corrosion hauv cov pas kub nruj
Kev tsim seamless xyuas kom muaj kev ntseeg siab hauv cov seem siab siab tseem ceeb; Ntau hom loj rau ntau hom boiler
