- Product Description
-
Ductile iron wide tolerance stepped coupling is a coupling used to connect two pipes or fittings of different sizes. It is made of ductile iron, which is a cast iron that is more flexible and durable than traditional cast iron.
The wide tolerance design of the coupling allows a larger range of pipe sizes to be connected, thereby reducing the need for multiple couplings and fittings. The stepped design of the coupling provides a safe and tight fit between the pipes, ensuring a leak-free connection.
Ductile iron wide tolerance stepped couplings are commonly used in industrial applications such as water and wastewater treatment plants, and oil and gas pipelines. They are also used in plumbing and HVAC systems to connect pipes of different sizes.
Overall, the ductile iron wide tolerance stepped coupling is a reliable and cost-effective solution for connecting pipes of different sizes. It can provide a safe and leak-free connection and can withstand the requirements of various applications.
• Wide OD range: 21mm on average.
• Small number of models with nominal diameter.
• Reliability:
-When the gasket between the end flange and the sleeve is compressed to the surface of the pipe, the permanent leak-proof joint.
-Corrosion protection: Epoxy powder coating (150 μm) and Dacrosome®Gr.B for 500 bolts.
• Ease and speed of installation:
-Angular deflection ± 6 °.
-Absorbs expansion and contraction.
-Adapt to dislocation.
-Important set gaps.
Conform to the standard:
-NF A 48-830: Cast Products-Ductile Iron
Pressure PVC drinking water pipe fittings.
-NF EN 545: Ductile iron pipes, fittings, accessories and their joints for water pipelines-Requirements and test methods.

Common Problem
★ 1. Cracks and fractures: Rubber rings may experience cracks and fractures during use due to stress or aging.
The treatment method can be to repair or replace rubber rings with cracks and fractures. Rubber patches or glue can be used for reinforcement during repair.
★ 2. Deformation and hardening: Rubber rings may undergo deformation and hardening when used for a long time or exposed to external environments such as high temperatures and chemicals.
The solution can be to replace the deformed and hardened rubber rings. In addition, appropriate maintenance measures can be taken, such as avoiding exposure to extreme temperatures and using suitable lubricants, to extend the service life of the rubber ring.
★ 3. Corrosion and aging: Rubber rings can experience corrosion and aging after prolonged use or exposure to corrosive effects such as chemicals and oxygen.
The solution can be to replace the rubber rings that have corrosion and aging. In addition, appropriate maintenance measures can be taken, such as storing in a dry, cool, and well ventilated environment, to extend the service life of the rubber ring.
★ 4. Friction damage: Rubber rings may experience friction damage when in contact or friction with other hard objects.
The treatment method can be to repair or replace the rubber ring with friction damage. Rubber patches or glue can be used for repair.
