HGFF GROUP Co., Ltd. has given an impetus to several industries during the last three decades, as We are certified to cater to the rigid and stringent requisites of the most critical of industries. Lap Joint Flanges are used with a stub end, which is welded to the pipe. Alloy Steel Lapped Joint Flanges are designed in a way that they swing over the pipe without the need to be welded. As they do not come in contact with the inner fluid, they do not corrode and can be re-used. Our ANSI B16.5 Stainless Steel Flanges are inexpensive and widely useful. In addition, they can be easily assembled and dismantled for a quick inspection
