Loose Flanges are used with an identical stub-end that enters the inside of the  Flange. The main advantage of this type of Flange is that once the pipe welds to the insert stub-end, these flanges can be rotated for more natural alignment of the bolting holes. However, these Loose Flanges and their stub ends can hold pressure about the same as slip-on flanges. Therefore, they are not suitable for situations with extreme external or changing loads of force. However, they give an improvement in a piping system that needs frequent dismantling for inspection or to remove build-ups.

At our manufacturing and testing facility, after completing each product batch, we perform their examination to meet the buyer’s expectations. Besides, we make products that can sustain in extreme solutions. Every batch of products is designed and produced by considering industry trends and the expectations of premium clients. Besides, we give products that are efficiently workable and long-lasting even for years.

Our company Nextgen Steel & Alloys have hired production experts to keep product quality within desired specifications. We fabricate product batch by performing different producers such as annealing, forging, forming, and cold working. Besides, we ensure to supply products that require less after instalment maintenance and care. We match the product specifications and quality standards using globally renowned standards for these flange products. We provide standard labelling and packaging along with standard shipping of our flanges.
