Alfa Chemistry Testing Lab is the world's leading third-party testing company, which provides customized pipe and pipe fitting testing solutions for building materials R&D companies, developers, builders, government agencies and individuals.
Pipe is a necessary material for construction projects. Commonly used are water supply pipes, drain pipes, gas pipes, heating pipes, wire ducts, rain pipes, etc. In the event of a pipe failure, the cost and time required to find the root cause for repair is long. More importantly, the failure of the pipe may endanger life. Alfa Chemistry Testing Lab provides pipe and pipe fitting testing solutions to ensure your products undergo comprehensive pressure, aging and degradation testing.

Techniques for pipe, pipe fitting testing
Metallographic Microscope
The metallographic microscope is a commonly used inspection instrument for metal materials, and is also applicable for pipe materials. By observing the microstructure, grain size, and inclusions of the cross-section of pipe materials under the microscope, the performance and quality of the materials can be determined to see if they meet the requirements.
Ultrasonic Flaw Detector
The ultrasonic flaw detector is an important tool for non-destructive testing of pipe materials. Utilizing the characteristics of ultrasonic wave propagation, it can detect whether there are any defects or cracks on the surface and interior of the pipe materials, thus evaluating the quality of the pipe materials.
Hardness Tester
The hardness tester is used to test the hardness of pipe materials. The test results can be used to determine whether the mechanical properties and durability of the materials meet the standards. Pipelines need to bear certain loads and internal pressures, so the hardness of pipe materials is an important indicator.
Tensile Testing Machine
The tensile testing machine is also a commonly used pipe material testing instrument, mainly used for the evaluation of mechanical properties of materials. During the tensile test, the tensile strength, yield strength, and elongation at break of the pipe materials can be tested and compared with the standard requirements.
Chemical Composition Analyzer
The chemical composition analyzer can analyze the main elements and impurities in pipe materials, thereby determining whether the pipe materials meet the standard requirements. Through the analysis of chemical composition, the mechanical properties and corrosion resistance of the pipe materials can be evaluated.

Degradation Analysis of Polymer Pipe Materials for Water Supply Systems
Khan, Imtiaz Afzal, et al. Chemosphere 291 (2022): 132669.
Municipal water supply systems are composed of polymer pipelines made of materials such as polyethylene (PE) and polyvinyl chloride (PVC), which are in contact with chlorine-based disinfectants. The reactivity of HOCl and ClO2 with the polymer materials leads to early degradation of the distribution system. The high oxidation potential of HOCl and ClO2 causes premature failure of the pipes, accelerating the depletion of antioxidants and the embrittlement of the advanced materials.
In this study, accelerated aging experiments were conducted to evaluate the oxidation of high-density polyethylene (HDPE), low-density polyethylene (LDPE), unplasticized polyvinyl chloride (UPVC), and high-impact polyvinyl chloride (Hi-PVC) pipes.
Defect Characterization of Thermoplastic Composite Pipes
Okolie, Obinna, et al. Heliyon (2023).
Thermoplastic composite pipes (TCPs) are recognized to have advantages over other pipes, as they offer flexibility, including suitability for purpose, lightweight, and non-corrosive properties. However, during the TCP manufacturing process involving the consolidation process, certain defects may be generated within the material due to various parameters, which could affect the long-term performance of the pipes, as the generated defects may lead to in-service defects.
The shape, type, and dimensions of the composite components, as well as the application type, determine the selection of the appropriate manufacturing process (melt-fusion technology for TCPs). Understanding the manufacturing defects is crucial, as they are the primary causes of material performance variations and potential causes of failures under service conditions.
Investigation on Microplastics Release Behavior of Plastic Pipe Materials under Ozone Exposure
Zhang, Xinyue, Tao Lin, and Xiaoxiang Wang. Environmental Pollution 296 (2022): 118758.
Microplastics (MPs) have been detected in drinking water, and the plastics used in water treatment and distribution processes are a potential source of MPs. Disinfectants, such as chlorine, chloramines, chlorine dioxide, and ozone, are widely used in drinking water treatment plants and secondary disinfection networks, and the water pipes are typically exposed to oxidative environments. Ozone, due to its strong oxidizing properties, is commonly used for supplementary disinfection in residential secondary water supply systems. Plastic materials are often used for small-diameter cold and hot water pipes in residential secondary water supply systems, and some plastic components in the system may be exposed to ozone or even residual ozone.
The changes in the physicochemical properties of plastic pipe materials after ozone exposure were investigated, including ATR-FTIR spectroscopy, OIT method, and SEM analysis. The introduction of carbonyl groups, changes in oxidation induction time, and surface morphology changes were detected after ozone exposure.
