[Verification Case] Investigation of the Cause of Refrigerant Leakage in Welded Plate Heat Exchangers

[Verification Case] Investigation of the Cause of Refrigerant Leakage in Welded Plate Heat Exchangers

Clarifying the cause of 'freezing and expansion' in four steps! Introduction of scientific approach verification cases.

We would like to introduce a scientific approach to investigating the causes of refrigerant leaks in welded plate heat exchangers. In the visual inspection, no foreign objects or blockages were found at the cold water inlet and outlet sides, and no external deformations were observed. 【Investigation Overview】 ■ Visual Inspection ■ Air Tightness Test ■ Dissection Investigation ■ Water Quality Test 【Verification Results】 Based on the deformation characteristics of the plates, it is determined that the cause was the expansion of cold water inside the plates due to freezing. Once freezing occurs inside the plates, the circulation flow rate in that area decreases, leading to repeated freezing and increased deformation. In areas other than the deformed sections, no impact was observed on the plate materials, which are stainless steel and copper solder. Therefore, it is concluded that the cause of the gas leak was an incidental issue due to the removal of deposits from previously frozen areas. As a countermeasure, regular water quality management and maintenance are being implemented for improvement. *For more details, please refer to the PDF document or feel free to contact us.

Clarification of odor-causing substances and chemical proof of the intrusion route through odor cause investigation.

Clarification of odor-causing substances and chemical proof of the intrusion route through odor cause investigation.

It can be utilized for the impact of exhaust gases from facilities that cook with oil on downwind facilities!

We conduct "investigations into the causes of unusual odors to identify the substances responsible and chemically prove the pathways of intrusion." Through on-site investigations (sample collection) and chemical analysis, we can chemically prove the "identification of the substances causing the unusual odors," the "proof of the pathways of intrusion," and whether what is emitted from the source matches the "contaminants." We have received feedback from customers stating that they had a chimney extension constructed for the store that emitted the unusual odor, allowing the exhaust outlet to be installed above the height of the store building. [Features] ■ The investigation results serve as chemical evidence, enabling requests for improvements to the source store regarding what is emitted from the source. ■ The investigation results serve as chemical evidence, allowing requests for cleaning of contaminated items at the source store. *For more details, please feel free to contact us.

Exterior wall tile peeling investigation

Exterior wall tile peeling investigation

Are there any tiles that are lifting or peeling? Properly analyze the components of the defective areas to identify the cause.

Our company can chemically investigate the causes of tile lifting and detachment by understanding the poor application of water absorption adjusters and the presence of residual release agents on the detached exterior wall tiles. It is possible to clarify and improve the causes of tile detachment (residual release agents, poor application of water absorption adjusters). If tile lifting and deterioration are left unaddressed, there is a risk that the exterior wall may detach and cause harm to third parties. Please feel free to contact us when you need our services. [Features] ■ It is possible to chemically investigate the causes of tile lifting and detachment. *For more details, please download the PDF or feel free to contact us.

[Metal Materials Brittle Fracture Cases] Investigation of Fracture Causes in Quenched and Tempered Parts

[Metal Materials Brittle Fracture Cases] Investigation of Fracture Causes in Quenched and Tempered Parts

Identify the type of fracture from the fracture morphology remaining on the fracture surface! A case study on investigating the cause of metal component cracking.

Here, we present a case of brittle fracture, which is a type of destruction. Upon further microscopic observation (using an electron microscope) of the fracture surface, features that were not apparent in macroscopic observation (visual inspection) became clear. From the microscopic observation images magnified approximately 1000 times, the fracture surface of the metal component displayed characteristics of cleavage fracture and suspected cleavage fracture. These are characteristic fracture surfaces observed in brittle fractures, allowing us to conclude that this metal component was fractured in a brittle manner. 【Case Summary】 ■ Features that were not apparent in macroscopic observation became clear ■ Shapes of cleavage fracture and suspected cleavage fracture were observed ■ It was determined that the fracture occurred in a brittle manner *For more details, please download the PDF or feel free to contact us.
