Description
HeBei Pengrun Pipe Fittings Manufacturing Co., Ltd. has given an impetus to several industries during the last three decades, especially through its outstanding products and extraordinary services. We are certified to cater to the rigid and stringent
requisites of the most critical of industries. We are manufacturers, suppliers and exporters of Short Stub Ends, stub ends that have a smaller hub length, as opposed to Long Stub Ends, that have an elongated one. They are alternative to welded ages: they play the role of rotating backup flanges. Manufactured using the best machinery and resources, these Fittings are a cost-effective product as it is not necessary that the material from which the stub end is made matches the piping material. Let us know your industry
requirements and we can furnish you customized Stainless Steel Short Stub
Ends as well.
