ERW pipes, or Electric Resistance Welded pipes, are known to be highly durable, and strong and are comparatively cheaper. These attributes make them suitable for various water supply systems as follows. In this blog, we will discuss the role of casings in ERW pipes, the material used, and the various sectors where these casings can be useful
What is a Casing ?
In the context of ERW pipes, a casing is a covering or a sheath that is put around the pipe. It plays the role of protecting the pipe from any form of external aggression and other forces of nature in order to make the water supply system efficient and long-lasting. Casing plays a crucial role in protecting the ERW pipes from corrosion, mechanical damage, and wear and tear
Material Selection for Casings
Selecting the right material for casings is crucial for ensuring the optimal performance and durability of ERW pipes. Here are some commonly used materials
- Carbon Steel : Carbon steel is highly praised for its strength and toughness, and therefore widely used for casings in ERW pipes. Stress is also well resisted by this material and this is a very important characteristic when it comes to pipework where pressure is always a factor. Its durability makes it possible for pipes to endure the harsh conditions of supply systems of water to deliver their services efficiently and for a long time. Also, carbon steel casings are inexpensive and easy to obtain, which makes them even more suitable for major civil construction works.
- Stainless Steel : Stainless steel casings are particularly preferred because they do not corrode or rust easily. This characteristic is especially relevant for pipes that are applied for water supply systems as the pipes are exposed to moisture and other aggressive agents. Stainless steel is long-lasting and does not require frequent replacement or repair hence it is widely used in many applications. It does not degrade easily, thus, it does not require frequent replacements and repairs, which makes it a cost-effective and efficient solution for shielding Electric Resistance Welded pipes.
- PVC (Polyvinyl Chloride) : PVC is a lightweight, cost-effective material that is resistant to corrosion and chemical damage. This makes it an excellent choice for casings in Electric Resistance Welded pipes. PVC casings are easy to install due to their lightweight nature, reducing labor costs and installation time. Additionally, PVC has a long lifespan, providing durable protection for ERW pipes in various environmental conditions. Its resistance to chemical reactions ensures that it remains stable and effective over time, even when exposed to harsh substances.
- HDPE (High-Density Polyethylene) : HDPE casings offer excellent resistance to impact, chemicals, and environmental stress. This material is highly flexible and durable, making it suitable for various water supply applications. HDPE's ability to absorb impacts without cracking or breaking ensures that the ERW pipes it protects remain intact and functional, even in challenging conditions. Moreover, HDPE's resistance to a wide range of chemicals makes it an ideal choice for environments where chemical exposure is a concern. Its flexibility allows it to adapt to different installation scenarios, providing reliable and long-lasting protection for Electric Resistance Welded pipes
Where Can Casings Be Used?
Casings for ERW pipes are versatile and can be used in a wide range of applications. Here are some notable examples
- Sewage Treatment : Because ERW pipes are a lot less expensive compared to seamless steel pipelines, it is also typically used in sewage treatment facilities. Casings secure the ERW pipe from severe chemicals and abrasive gruntlings flowing via its thick layer of safety rubber. This protective layer ensures that the pipes keep their structural integrity and can run smoothly even under arduous conditions.
- Building Drainage Systems : Many builders use these ERW pipes with casings in building drainage systems. The casings hold up against corrosion and physical damage, ensuring that the drainage system works properly wherever it is needed. This is even more critical when it comes to high-rise buildings, where the drain must remain durable and solid for a long time.
- Municipal Road Drainage Systems : ERW pipes are protected by casings in municipal road drainage systems, to prevent external damage due to heavy traffic and environmental factors. The casings shield the pipes to extend their operational life, which is cost-effective in reducing road drainage maintenance requirements.
- Urban Water Supply : Casings are crucial in urban water supply systems, where Electric Resistance Welded pipes are used to transport water over long distances. The casings protect the pipes from environmental factors such as soil movement, corrosion, and physical damage. This ensures a reliable and uninterrupted water supply to urban areas
Conclusion
ERW pipes and their casings are used in several water supply systems. The material used in the casing is very sensitive in determining the durability of the pipes, their resistance to damage, and their overall performance. Thus, it is possible to understand the significance of casings and their usage in sewage treatment, building drainage systems, municipal road drainage systems, and urban water supply to realize the contribution to the efficiency and durability of the Electric Resistance Welded pipes.
