1. Lo lus nug: Dab tsi yog cov kev siv tseem ceeb ntawm cov high -cov raj seamless?
Teb: Cov raj no tau siv dav hauv kev ua tshuaj lom neeg, petrochemical, marine, hluav taws xob tsim hluav taws xob, thiab kev siv hluav taws xob kub siab -. Lawv zoo tagnrho rau kev tuav cov xov xwm corrosive thiab siab - qhov kub thiab txias.
2. Nqe Lus Nug: Cov khoom tseem ceeb ntawm Inconel 625, Incoloy 800, thiab Hastelloy C276 yog dab tsi?
Teb:
Inconel 625: Exceptional oxidation thiab corrosion kuj, siab zog ntawm siab kub, resistant rau chlorides thiab lwm yam aggressive tshuaj.
Incoloy 800: Zoo heev oxidation tsis kam thiab siab - qhov kub thiab txias, feem ntau siv hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
Hastelloy C276: Cov tshuaj tiv thaiv zoo tshaj plaws hauv oxidizing thiab txo qhov chaw ib puag ncig, tiv taus cov tshuaj chlorides, muaj zog acids, thiab kev daws teeb meem tshuaj.
3. Lo lus nug: Cov qauv thiab cov ntawv pov thawj dab tsi ua cov raj seamless ua raws li?
Teb: Lawv tau tsim raws li ASTM cov qauv (xws li ASTM B444, B409, B622), kom ntseeg tau cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab qhov tseeb qhov ntev. Cov ntawv pov thawj zoo li Mill Test Reports (MTRs) thiab ISO / CE ua raws li feem ntau yog muab.
4. Lo lus nug: Yuav ua li cas yog qhov zoo thiab kev ntseeg siab ntawm cov raj no muaj tseeb?
Teb:
Kev ntsuam xyuas tshuaj muaj pes tsawg leeg rau kev txheeb xyuas cov alloy.
Mechanical xeem: tensile zog, tawm los zog, hardness.
Tsis yog -kev kuaj kev puas tsuaj (NDT): ultrasonic lossis eddy tam sim no kuaj rau qhov tsis xws luag.
Visual tshuaj xyuas rau saum npoo zoo thiab qhov ntsuas qhov ntev.
5. Lo lus nug: Dab tsi yuav tsum tau ceev faj thaum lub sijhawm teeb tsa thiab ua haujlwm?
Teb:
Tsis txhob thermal shock thaum cua sov los yog txias.
Ua kom muaj kev sib raug zoo thiab kev txhawb nqa hauv cov kav dej.
Tiv thaiv kev sib cuag nrog cov hlau tsis sib xws kom tsis txhob galvanic corrosion.
Follow maximum operating temperature and pressure limits for each alloy type.
