How to choose stainless steel seamless elbows? Three tips to teach you:
1. Look at the seams
Stainless steel seamless elbows are similar to fully pulled noodles, while inferior products have welding gaps.
2. Smell
Stainless steel seamless elbows only have a metallic smell, while inferior products may have a pungent sour smell due to mixed scrap steel.
3. Test strength
Tap with a hammer for comparison. The sound of stainless steel seamless elbows is as crisp as a silver bell, while inferior products have muffled sounds due to hidden injuries.
