Stainless steel seamless elbows are like installing a “steel knee” on the pipeline – allowing water, oil and gas, and chemical liquids to turn smoothly, without bulging, cracks, or rust! Oil pipelines, chemical plants, and hospital oxygen pipes are all in use. They are ‌pressure-resistant and resistant + lifelong non-retirement‌, and are the “hexagonal warriors” in the elbow industry!
If you want to buy a pair of stainless steel seamless elbows, the first step is to look at the surface steel stamp (equivalent to identity proof), the second step is to measure the thickness, and finally check whether the inner wall has defects.
The outer side of the stainless steel seamless elbow must have a steel stamp of the relevant material. If not, there is no need to guess that it is a fake or second-hand refurbished product; use a caliper to measure the thickness of the stainless steel seamless elbow at the bend. If the difference with the straight pipe section exceeds 10%, it is judged as a defective product; use the flashlight of a mobile phone to illuminate the elbow. If scratches and bumps are found on the inner wall, it is considered that the quality will be affected and it is recommended to return the goods.
