I would like to ask the experts: how to inspect waterproof sleeves, elbows, tees, flanges, gaskets, and seamless steel pipes? What aspects should be paid attention to during the inspection? Please provide a detailed explanation; I’m a beginner. Thank you
I’m here to learn from everyone!* ! Please give me your advice. Ah ah
Is it to check for leaks or a quality inspection?
Alas, nothing at all, such a disappointment! ! !
For this guy, it’s fine as long as nothing is missed; a quick inspection should be enough. If it’s about checking the materials, it’s sufficient that they are smooth and flat with no burrs; if necessary, sampling for flaw detection can be carried out. As for the material, there is nothing to check – it’s just carbon steel, so no material testing is required. There are standards for everything; HGT20592~20635-2009 for steel pipe flanges, gaskets, and fasteners ； GB12459-2005 Steel Butt-Welded Seamless Fittings ； GB8163-2008 Seamless Steel Tubes ； GBT8163-2008 Seamless steel pipes for fluid transport; check it out by yourself.
