Piping Materials Expertise

Carbon Steel

Carbon steel piping is an essential part of many industries, from construction to manufacturing. Its durability and strength make it ideal for transporting liquids and gases under high pressure. Additionally, carbon steel piping is relatively inexpensive and easy to work with, making it a popular choice for a variety of applications. While carbon steel piping is generally very reliable, it can be susceptible to corrosion if not properly protected. 

Chrome

Chrome industrial piping is used in a variety of applications. The sleek, silver appearance of chrome pipes is achieved by applying a thin layer of metal to the surface. This process is known as electroplating, and it provides a number of benefits. For one, it creates a smoother surface that is less likely to corrode or leach chemicals. Additionally, electroplating increases the hardness of the pipe, making it more durable and resistant to wear and tear. As a result, chrome-plated pipes are an excellent choice for use in high-pressure or high-temperature environments.

Stainless Steels

Stainless steel pipes are used for everything from carrying liquids and gases to transporting solids. It is also a key material in the construction of storage tanks and process vessels. Stainless steel piping is strong and durable, and it can withstand high temperatures and pressures. It is also resistant to corrosion, making it an ideal choice for many industrial applications. 

Duplex Steels

Duplex steel is a popular choice for industrial piping applications due to its superior strength and durability. Unlike other materials, duplex steel can resist corrosion from both acidic and alkaline substances, making it an ideal choice for handling harsh chemicals. Additionally, duplex steel is highly resistant to pitting and crevice corrosion and can be used in saltwater environments. In terms of strength, duplex steel is approximately twice as strong as austenitic stainless steels and is frequently used in high-pressure applications. 

Nickel-based Alloys

Nickel-based alloy piping is a type of pipe that is made from a alloy of nickel and other metals. It is commonly used in high-temperature applications, such as in power plants and chemical plants. Nickel-based alloy piping is known for its high strength and resistance to corrosion. It is also resistant to embrittlement at low temperatures. In addition, nickel-based alloy piping has a high resistance to stress corrosion cracking. As a result, it is an excellent choice for use in critical applications where reliability is paramount.

Aluminum

Aluminum piping is a versatile and durable choice for industrial applications. Its light weight makes it easy to handle and transport, and its smooth surface helps to reduce friction and protect against corrosion. In addition, aluminum piping is highly resistant to temperature changes and can withstand high pressures without buckling or breaking. As a result, it is an ideal choice for carrying liquids, gases, and other materials through factories and other industrial settings. Whether you need to transport hazardous materials or deliver clean water to a factory floor, aluminum piping is up to the task. 

Jacketed Piping

Jacketed piping consists of two pipes, one inside the other. The space between the two pipes is usually filled with insulation, which helps to keep the contents of the pipe at a constant temperature. Jacketed piping is often used for transporting sensitive materials, such as chemicals or food products. It can also be used for carrying hot or cold liquids, as well as for steam piping. Jacketed piping is more expensive than traditional piping, but it offers superior temperature control and increased safety.

Quality Assurance and Testing

Radiographic examination

Radiographic examination is a critical step in the manufacturing process for many types of piping. The process uses X-rays or gamma rays to create an image of the interior of the pipe. This image can then be used to identify any flaws or defects in the pipe wall. Radiographic examination is a non-destructive testing method, which means that it does not damage the pipe being examined. This makes it an ideal quality control measure for many industries. In addition, radiographic examination is relatively quick and easy to perform, meaning that it can be done on a regular basis without disrupting production. 

Magnetic particle examination

Magnetic particle examination is a form of nondestructive testing that is used to detect surface and subsurface defects in ferromagnetic materials. The process involves the use of magnetic fields to magnetize the material being tested. Iron filings are then applied to the surface of the material, and the pattern of the filings is used to identify any defects that may be present. Magnetic particle examination can be used to detect cracks, voids, and other imperfections in a wide range of materials, including metals, welds, and castings. The process is fast, efficient, and relatively easy to perform, making it an important tool for quality control and failure analysis.

Liquid penetrant examination

Liquid penetrant examination is a type of nondestructive testing that is used to detect cracks, voids, or other defects in a material. The process involves applying a penetrant to the surface of the material and allowing it to seep into any cracks or voids. The excess penetrant is then removed, and a developer is applied. The developer helps to highlight any areas where the penetrant has penetrated, making it possible to detect even very small defects. Liquid penetrant examination can be used on a variety of materials, including metals, plastics, and ceramics. It is especially well suited for detecting defects in complex shapes or buried interfaces.

Ultrasonic examination

Ultrasonic examination (UT) is a non-destructive testing technique that uses high-frequency sound waves to inspect industrial piping for defects. UT is typically used to detect cracks, corrosion, and other types of damage in metals, plastics, and composites. The test can be performed on both new and installed pipes, and it does not require the removal of any coatings or linings. UT is often used in conjunction with other NDT methods, such as visual inspection and radiography.

Penetrant testing

Penetrant testing is a nondestructive test method used to locate leaks and defects in industrial piping. The test is performed by applying a liquid penetrant to the surface of the pipe and then using a fluorescent light to inspect the area for leaks. This method is often used on pipes that are difficult to access or that contain hazardous materials, as it does not require the use of any sensors or probes.
