Our Story

Let us make it… that’s our job.

Since 1960, our expert pipe flange manufacturers have mastered the art of crafting flanges. For all our machined products, we leverage state-of-the-art technology to get the job done in our New Jersey facility. As a flange manufacturer utilizing the latest technology, we can save your business both time and money. Understanding that time is money; we promise to always help you hit your deadlines.

If the part’s description says “Flange,” then send it to us. We will help you get the right item. Not sure what something is? That’s OK. We understand the various nuances of the pipe valve and fitting industry and are here to help. The Piping Supplies team understands that customer loyalty and trust are essential to the success of our business. For this reason, Piping Supplies is committed to creating consistent, reliable work at the highest industry standards. We hope to not only deliver effective solutions, but also help our customers with any pipe supply questions they may have.

We have years of experience working as a flange manufacturer and ,since our establishment, have machined nearly every kind of flange out there. One of our most requested flanges would most likely be the weld neck flange. Larger applications with high-pressure needs require a weld neck flange. We also handle slip on flanges. These are the alternative to weld neck flanges as they make it easy to weld the outer diameter of a pipe. Our experts can also help you with your blind flange, counter bore socket weld flange, threaded/companion flange and lap joint flange needs. If you have any questions regarding any of our flange types, please don’t hesitate to reach out to our helpful sales staff and customer service team.
