Key points of this article
- Importance of regular inspections: Inspections are essential for preventing factory equipment problems or malfunctions and for ensuring their safe and efficient operation.
- Measures to prevent inspection errors across the factory: Errors can be reduced by automating data entry and management processes, and establishing systems for information sharing to minimize reliance on specific individuals.
- Specific points to note when performing inspections on hose piping: Particular attention should be paid to issues such as loose hose clamps, kinked or collapsed hoses, deteriorated couplings, pinhole formation, and hose hardening.
1. 1. What is the purpose of inspections?
Inspections are performed to detect potential problems or malfunctions in factory equipment beforehand and to ensure safe and efficient operation. In particular, machinery and equipment that have been used for long periods are prone to wear and deterioration, which can lead to loosened parts and unforeseen accidents. Regular inspections enable these problems to be detected at an early stage, allowing for repairs and maintenance to be carried out. This prevents line stoppages and product defects, while ensuring worker safety.
2. Measures to prevent inspection errors
Now, here’s a question for everyone from Hose Adviser PRO.
What is an effective measure for preventing human error during inspections?
Select from among A, B, and C below.
A. Appointing a trusted individual from among the workers to serve as a leader and giving them the discretion to make decisions
B. Simplifying and reducing the number of inspection items to make inspections easier to understand
C. Introducing digital tools that automate the input and management of inspection data
The correct answer is C. Introducing digital tools that automate the input and management of inspection data.
To minimize the possibility of human error, it is crucial to not only automate processes but also to simplify and clarify inspection items. It is also important to create a system that enables the sharing of work procedures and check items, and which is not dependent upon specific personnel.
Specific points regarding hose piping inspections
Hoses are frequently used at factories and are particularly susceptible to the effects of pressure and temperature. Any failure to perform proper inspections and maintenance can increase safety risks. The following are points to pay particular attention to when inspecting hoses.
Hose hardening: Hoses made of soft PVC can harden due to the loss of additives, causing leakage or rupturing. Once a hose hardens, there is no alternative but to replace it.
Hose clamp looseness: Loose clamps can cause fluid leakage or hose disconnections. It is important that a torque wrench be used to check for proper tightening and for periodic retightening.
Hose kinking and collapsing: Bending hoses beyond their permissible bending radius can cause them to kink or collapse, leading to pressure losses or rupturing. Hoses that are deteriorated or show signs of kinking or collapsing should be replaced immediately.
Deteriorated couplings: Rusty or broken couplings can result in fluid leaks or quality problems. Make sure to regularly replace deteriorated couplings.
Pinhole formation: Small holes that form in a hose (pinholes) can expand due to pressure and cause leakage or rupturing. Even when small holes form, hoses should be replaced immediately.
Hoses require regular inspection and replacement when needed. It is also important to select the appropriate hose and coupling for your application and purpose.

Regular inspections are essential for improving safety at factories and production sites. When inspections are not performed sufficiently or involve human error, there is an increased risk of serious accidents. In this article, Hose Adviser PRO will explain the purpose of inspections performed throughout the entire factory, as well as measures to prevent mistakes and specific points regarding hose piping inspections.
