Condensation tends to form on the surface of hoses carrying low-temperature fluids, and the dripping water it causes can result in problems. One way to prevent or reduce condensation is to minimize the temperature difference between the hose and the surroundings and to reduce the ambient humidity. However, because using air conditioning equipment to adjust the temperature and humidity inside the factory or around hoses can be expensive, it is common to insulate the surface of hoses. In this article, Hose Adviser PRO will describe hose insulation methods. Key points of this article Hose insulation method 1 — Wrapping with polyethylene foam (PEF) Let’s start with a question for everyone […]

When a hose is used to carry oil, certain types of oil may cause the hose to harden rapidly. Because hardened hoses cannot be returned to their original condition and may lead to various types of problems such as kinking or collapsing, they should be replaced as soon as possible. In this article, Hose Adviser PRO will explain how certain types of oil can cause a hose to harden, and how to prevent kinking and collapsing. Key points of this article The secret behind PVC hose flexibility Polyvinyl chloride (PVC) resin is often used to make general-purpose hoses. PVC resin is hard at room temperature and cannot be bent. However, […]

Static electricity issues become more frequent during dry seasons, and when this static electricity builds up in a hose, raw materials start adhering to the inner lining, obstructing flow and causing clogs. Such clogging can be prevented by taking proper measures against static electricity, leading to stable production and more efficient work. In this article, Hose Adviser PRO will explain key points of static electricity countermeasures for increased productivity, work efficiency, and safety. Key points of this article How is static electricity generated in hoses? Now, here’s a question for everyone from Hose Adviser PRO. What is the main reason static electricity builds up in hoses?　Select from among A, B, […]

Hoses can harden over time for a variety of reasons, including the temperature and type of fluid they carry (chemical, oil, etc.), the environment they are used in, and how long they have been in use. Hardened hoses cannot be returned to their original condition and can cause not only punctures (ruptures) or cracks but also various other problems. In this article, Hose Adviser PRO will explain causes and countermeasures for punctures (ruptures) and cracks caused by heat. Key points of this article Learn the secret behind what makes PVC hoses flexible Now, here’s a question for everyone from Hose Adviser PRO. Why do soft PVC hoses harden during use?Select […]

Using chemicals in a hose can cause the hose to harden over a short period with certain types and concentrations of chemicals. Because hardened hoses cannot be returned to their original condition and may cause various types of problems, they should be replaced as soon as possible. In this article, Hose Adviser PRO will explain how certain chemicals can cause a hose to harden, and how to prevent this from happening. Key points of this article Why are PVC hoses soft? Polyvinyl chloride (PVC) resin is often used to make general-purpose hoses. PVC resin is hard at room temperature and cannot be bent. The PVC resin used in hoses, however, […]

Maintenance of hose piping is essential for preventing fluid leaks and hose disconnections. The retightening of hose clamps is also particularly important. Hose Adviser PRO explains why retightening is necessary and how to perform retightening, as well as methods to further reduce the likelihood of fluid leaks and hose disconnections. Key points of this article So, why do hose clamps need to be retightened? Hose clamps are used to secure hoses and ensure a tight seal between the hose and the coupling. This reduces the likelihood of fluid leaks and hose disconnections, even when hoses are under pressure. However, because the elasticity of plastic hoses at the point where the […]
