Immaculatam ferro Flangeet ipsumflangeMaterial quam ad identify? Quam distinguere dure materiam de duabus generis flanges est relative simplex. In his DHDZ LABIUM Manufacturer accipit vos simpliciter intelligere simpliciter ad distinguere materiam duplici generis products.
I. Primum est complevitflange, flangesurface without galvanized, general product brush anti-corrosion paint, gas or oil to wipe clean surface, and then use a small amount of water droplets to the flange top, if carbon steel flanges is generally a few hours or even not to exceed a hours will have obvious tan rust (remember not to drip off water exposure, Or not necessarily can see), if it is stainless steel flange, generally will only leave a watermark, there will be no rust.
II. Nudus oculus:immaculatam ferro FlangeetCarbon Steel Flangecolor est actu magis obvious. Superficies immaculatam ferro LABIUM est lenis et superficies ipsum ferro LABIUM est fere paulo aspera. Erit manifestum est si duo flanges diversis materiae comparari.
Dupliciter duo modi potest dure distinguereAliquam ferro flangesaut ipsum ferro flanges. Hoc non potest confirmare quod est propria materia est, ut accurate determinare materiam de immaculatam ferro etCarbon Steel FlangeTum potest referri ad duo modi:
III. Aliquam Steel Liquid test, plerumque solum applicabilis adimmaculatam ferro FlangeSecundum mutationem coloris et color effectus temporis ad confirmandas est quaedam materia.

IV. Est etiam per modum saepe usus est perFlange Manufacturers, Quod est recta legere scanner. Potest verius deprehendere quod flange factum est, sed ejus pretium est relative sumptuosus, quod est a major defectus huius modum.
