From the names, we can conclude that the difference between the stainless steel seamless elbow and the stainless steel seamed elbow is that there is a seam around the elbow and it is seamless. So besides that, do you know what other methods can be used to identify them?
1. By observing the appearance
The inner and outer walls of stainless steel seamless elbows are smooth and have no welds; the inner and outer walls of stainless steel seamed elbows have welds. This is the most direct way to identify them.
2. By measuring wall thickness
The wall thickness of stainless steel seamless elbows is uniform; the wall thickness of stainless steel seamed elbows may become thinner due to welding.
3. Check the quality certificate
Stainless steel seamless elbow manufacturers provide quality certificates, including material certificates, pressure test reports, etc., through which stainless steel seamless elbows can be identified.
4. Pass the stress test
The pressure test was conducted to observe the deformation of the two under high pressure. The stainless steel seamless elbow has better pressure resistance.
The above points can help us distinguish between stainless steel seamless elbows and stainless steel seamed elbows. I hope it will be helpful to you!
