Our company specializes in the production of ductile iron pipe fittings，Adopting ost foam casting process technology, supporting full-automatic molding machine, intermediate frequency electric furnace,sand processing equipment, finishing equipment.Production and processing of high-quality pipe fittings.

The ductile iron materia features similar mechanical properties with carbon steel such as highmechanical strength,good ductility,and the same anti-corrosion performance as cast iron.Therefore,it has gradually become the world's most safe and reliable pipes and fittings in the field of watersupply and drainage.

The double-flange force-transmitting joint is a connecting component used in piping systems for flanged connections; it serves the dual functions of facilitating installation adjustment and transmitting axial forces. It consists of a main body, an expansion sleeve, a sealing ring, a gland, and force-transmitting tie rods.

Butterfly valves feature a simple structure, compact size, and light weight, consisting of only a few components. Furthermore, they allow for rapid opening and closing—requiring only a 90-degree rotation—making operation straightforward. Concurrently, these valves exhibit excellent fluid control characteristics. When a flanged butterfly valve is in the fully open position, the thickness of the disc constitutes the primary resistance encountered by the fluid flowing through the valve body; consequently, the pressure drop generated across the valve is minimal, resulting in superior flow control performance. Butterfly valves are available in two distinct sealing configurations: resilient sealing and metal sealing. In valves utilizing resilient sealing, the sealing ring may be embedded within the valve body or affixed to the periphery of the disc.

Connection for pipes in material ductile iron, steel,PVC,AC ect; Working pressure PN10/16/25; Maximum temperature -10℃ to +70℃; Suitable for portable water, neutral liquids and sewage; WRAS approved.

The Double-Flange Limited Expansion Joint consists of several main components: a body, a sealing ring, a gland, and a telescopic short pipe. Building upon the inherent capabilities of a standard loose-flange expansion joint, this design incorporates a limiting device that utilizes double nuts to lock the assembly at its maximum extension limit. The pipeline is free to expand and contract within its permissible range; however, should it exceed this maximum limit, the device acts as a mechanical stop, thereby ensuring the safe and secure operation of the pipeline. This product is particularly well-suited for connecting pipelines subject to vibration, or those featuring specific gradients or directional bends.

Based on the configuration of the sealing surfaces, gate valves can be classified into wedge-type gate valves and parallel-type gate valves. Wedge-type gate valves are further subdivided into single-disc, double-disc, and elastic-disc types; parallel-type gate valves are subdivided into single-disc and double-disc types. Based on the position of the valve stem threads, they can be classified into rising-stem valves and non-rising-stem valves.
