Stainless Steel Sanitary Food Grade Welded Concentric Pipe Reducer
 
Stainless Steel Sanitary Food Grade Welded Concentric Pipe Reduceris a Hygienic reducer stainless steel pipe fitting with polished, crevice-free surface, widely used in food, beverage, dairy and pharmaceutical pipelines. It is installed at the diameter transition section of straight pipelines, mainly used to smoothly connect pipes of different sizesand reduce fluid resistance without residue. Made of SS304/316L, it adopts welded connection and complies with 3A, DIN and ISO standards. It is divided into different size specifications from 1/2"to 6", featuring stable pressure resistance, easy cleaning and strict hygiene performance.
 
The core difference between Stainless Steel Sanitary Food Grade Welded Concentric Pipe Reducer and ordinary products lies in hygienic polishing, crevice-free designandfood-grade materials. The inner wall is smooth and residue-free, complying with strict hygiene standards such as 3A and DIN, while ordinary pipe fittings are prone to material buildup and fail to meet standards. Our products adopt high-purity 304/316L stainless steelwithprecision welding and no burrs, featuring higher dimensional accuracy and stable pressure resistance. We also support customized sizes and seals, with stricter quality inspection and longer service life, offering superior safety and stability over similar products.
