Description

HGFF Group Co.,Ltd. is a manufacturer, distributor and exporter of Threaded / Screwed Unions. It is an innovative company that has received its ISO certification and also ensures complete customer satisfaction. The Stainless Steel Screwed Union is a screwed
joint design and consists of three interconnected pieces. It is designed to allow easy, quick and convenient disconnection of pipes for maintenance or texture replacement. They are primarily used for maintenance and installation purposes. A Forged Threaded ANSI B16.11 Union provides a simple nut transition which allows an
easy release at any time. These fittings are used in low-pressure environments where the dismantling of a pipe is required often. These ASME B16.11 Threaded Unions are used to join pipes or tubes of different dimensions. The above-mentioned fittings are provided to the clients in accordance with the international standards and
specifications. These Fittings are made by HGFF Group Co., LTD. under the expertise of professionals. Modern equipment is utilized for manufacturing the Threaded / Screwed Union Fittings.
