Product Introduction

 Product Characteristics

KRH yoking flexible steel expansion joint can be used for pipe connection for the reliable performance and easy installation. Under low pressure, seal will be done through elastic deformation of seal ring; when pressure is increased, self-seal will be done through medium on seal ring, some space between pipe ends shall be kept to compensate displacement and flexure resulted from pipe¡¯s thermal expansion and cold compression. Yoking joints are widely used on pipes as fire fighting, mine, power, chemical industry and urban water supply, etc, special flange short pipes can be manufactured by order when the products are used to connect with pump, valve and pipe parts.
