Mechanical Testing
Petromaster provides a comprehensive range of materials testing services and employs a state-of-the-art test lab that allows us to provide the most accurate and reliable test results. Our test specimens are duly prepared for the evaluation of metallic and non-metallic materials.
Our materials testing services include, but are not limited to the following:
- Tensile and Bend Testing
- Hardness Testing
- Impact Testing
- Accelerated Stress Rupture Testing
- Fatigue Testing
The mechanical testing offered by Petromaster are always conducted as per ASTM, IS, DIN, NACE or other specified standards by the client. We are also specialized in elevated temperature tensile testing. Out mechanical testing department also performs impact tests (izod and charpy) within the temperature range from 50°C to 900°C.
Tensile Testing
Tensile testing helps to ensure your sample or material is fit for purpose and will not fail structurally. Tensile testing involves stretching the sample in one direction until it collapses, to establish the maximum stress the material can hold with. Once you know the stress value, you can make the decision and set the operating condition as per your choice so that the performance can be maximized and the risk can be nullified.
All tensile tests at Petromaster are performed in accordance with ASTM E8, A370, B557 and IS standards. We are experts in determining the mechanical properties of materials and help you to resolve technical issues in your industry.
Hardness Testing
Hardness testing is how your material will resist a scratch or dent by produced by other material. Hardness test results often correlate the other material properties, i.e. tensile strength. These results help engineers in material selection, lot verification and evaluating material processing.
In Petromater, we are performing various types of hardness testing followed by ASTM standards. Our hardness testing techniques include Vickers hardness testing as per ASTM E92, Brinell hardness testing as per ASTM E10, Micro-Vickers as per ASTM E384, and portable hardness testing as per ASTM E110.
Fatigue Testing
Fatigue testing is a type of materials testing used to evaluate the behavior of materials under cyclic loading conditions. It assesses how materials respond to repeated loading and unloading cycles, simulating real-world conditions where components may experience fluctuating stress levels over time. The primary objective of fatigue testing is to determine the endurance limit or fatigue strength of a material, which is the maximum stress level it can withstand for a specified number of cycles before failure occurs.
At Petromaster, we adhere strictly to industry-leading standards ASTM E466 for fatigue testing. This standard provides guidelines for conducting force-controlled constant amplitude axial fatigue tests on metallic materials under various conditions. It covers specimen preparation, test apparatus setup, testing procedures, data analysis, and reporting requirements. With a commitment to quality and adherence to established protocols, we provide our clients with trustworthy insights to support their engineering decisions and product development goals.
Impact / Charpy Testing
Impact testing is a method used to assess the resistance of materials to sudden force or impact. It involves subjecting a specimen to a controlled impact under specific conditions to evaluate its toughness, strength, and ability to absorb energy without fracturing.
We are following ASTM standards such as ASTM E23 for Charpy testing and ASTM D256 for Izod testing. Impact testing is essential for evaluating the mechanical properties and performance of materials. This standardized test helps ensure product quality, safety, and compliance with industry standards.
Accelerated Stress Rupture Test for RLA
Accelerated Stress Rupture Testing (ASR) is a specialized testing method used to assess the long-term stability and reliability of materials, particularly those operating under high stress and elevated temperatures. It involves subjecting test specimens to accelerated conditions, simulating prolonged exposure to harsh environmental factors, to predict material behavior over time.
We are dedicated to following the guidelines set forth by the ASTM E139 standard for accelerated Stress Rupture Testing (ASR) for the remaining life of in-service components subject to creep damage at elevated temperatures.
Chemical Analysis
Chemical compositional analysis is a crucial aspect of material testing, providing insights into the elemental composition of a substance. At Petromaster, our advanced laboratory facilities and expertise allow for precise and comprehensive chemical analysis of metallic and non-metallic materials. We utilize a range of state-of-the-art analytical techniques to determine the concentration of elements present within a sample. Our skilled chemists employ traditional laboratory techniques to conduct meticulous wet chemical tests, providing fundamental insights into the composition of substances. Through this method, we assess the concentration of key elements such as carbon, sulfur, nitrogen, and oxygen, supporting quality control, material characterization, and research endeavors with accuracy and reliability. Whether it’s for quality control, material identification, or research purposes, our chemical analysis services deliver precise results to support informed decision-making and ensure the integrity and performance of materials in diverse applications.
WPS & PQR Prepration
Petromaster offers comprehensive services for Welding Procedure Specification (WPS) and Procedure Qualification Record (PQR) preparation, essential for ensuring the quality and integrity of welded structures and components. Our experienced team works closely with clients to develop customized WPS tailored to their specific welding processes, materials, and application requirements. We follow industry standards and codes such as ASME, AWS, and API to create WPS documents that outline essential welding parameters, procedures, and techniques to achieve desired weld quality and performance.
In addition to WPS development, we conduct rigorous Procedure Qualification Record (PQR) testing to validate welding procedures and ensure compliance with regulatory standards. Our state-of-the-art testing facilities and expertise enable us to perform a range of mechanical and non-destructive tests on welded specimens, including tensile testing, bend testing, impact testing, and radiographic examination. With a commitment to excellence and adherence to industry best practices, Petromaster delivers reliable WPS and PQR solutions to support safe and efficient welding operations across various industries
Positive Material Identification (PMI)
Positive Material Identification (PMI) is a critical process used to verify the elemental composition and integrity of metallic materials. At Petromaster, we offer comprehensive PMI services utilizing advanced analytical techniques such as X-ray fluorescence (XRF) spectroscopy (Including handheld and laboratory based), etc. Our state-of-the-art equipment and experienced technicians enable rapid and accurate identification of materials, ensuring compliance with industry standards and regulatory requirements.
