Technical Methods		Hot-rolled/Cold-drawn/Hot-expanded
Testing Methods		There are several methods available for testing and inspecting materials. These include pressure testing, flaw detection, eddy current testing, hydrostatic testing, ultrasonic examination, and chemical/physical property inspection. Each method has its own unique benefits and serves different purposes. Pressure testing involves subjecting a material or system to a predetermined amount of pressure to check for leaks or structural integrity. This test is commonly used in industries such as oil and gas, aerospace, and manufacturing. Flaw detection is a process that aims to identify and locate any discontinuity or defect in a material. It can be done through various techniques such as visual inspection, liquid penetrant testing, magnetic particle testing, or radiographic testing. This method helps ensure the reliability and safety of different structures or components. Eddy current testing is a non-destructive method used to detect surface or near-surface defects in conductive materials. It works by inducing an alternating magnetic field into the material and measuring any changes in the field caused by the presence of defects. This technique is often used for inspecting metal alloys in industries like automotive, aerospace, or power generation. Hydrostatic testing involves filling a vessel or system with water or another liquid to test its strength and leak integrity. By subjecting the material to higher pressure, potential weaknesses can be identified. This method is commonly used in the assessment of pipes, pressure vessels, or storage tanks. Ultrasonic examination utilizes high-frequency sound waves to penetrate materials and detect internal flaws or defects. It is commonly used in the inspection of welds, castings, or forgings. Ultrasonic testing can provide accurate and detailed information on the size, location, and nature of any detected flaws. Finally, chemical and physical property inspection involves analyzing a material's composition, properties, and characteristics through various tests such as spectroscopy, microscopy, or mechanical testing. This type of inspection is crucial in determining if a material meets the required standards and specifications. In summary, these methods of testing and inspection provide valuable information about the quality, integrity, and performance of materials. Each technique has its own advantages and applications, allowing industries to ensure the reliability and safety of their products or structures.
Packaging		The pipes are carefully bundled with sturdy steel strips in smaller sizes, while larger pieces are kept loose. They are then covered with plastic woven bags and sealed in safe wooden cases. These cases are specifically designed for easy lifting during transportation. The packaged items can be loaded into 20ft, 40ft or 45ft containers or moved in bulk. The shipping method can also be customized according to the specific requirements of the customer.
