Stainless Steel Reducers
Jiangsu Sheye Metal is a leading manufacturer specialized in stainless steel pipe fitting-stainless steel reducers. Stainless steel reducer is one of the commonest stainless steel pipe fittings. Stainless reducer is the component in a pipeline that reduces the stainless pipe size from a larger to a smaller bore. The length of the pipe reduction is usually equal to the average of the larger and smaller pipe diameters. Stainless steel reducers can be mainly divided into two types: concentric stainless steel reducer and eccentric stainless steel reducer. Stainless steel reducers are usually concentric but eccentric reducers are used when required to maintain the same top-or bottom-of-pipe level. Stainless steel reducers are manufactured in inch and metric size. High quality, reasonable offer and super service make Sheye Metal win more market with positive company image. Sheye Metal is the quality source for your supplier system.
