But because of the various names used, some mistake black pipe for iron and wrongly assume that welding is difficult.Īlso, black pipe works well for a number of uses. As already indicated, welding is possible since this product is made from mild steel. So, black pipe is generically any ungalvanized steel pipe.īlack pipe is sometimes called black steel pipe, black iron pipe, and industrial pipe. The industry uses “ black pipe” as a term to differentiate between plain mild steel and galvanized pipe. Depending on the materials and welding process, the answer will vary. So, a simple yes or no is not enough to answer this question properly. But, if you need to purchase a large quantity, our experienced team can help you get the lowest price.If black pipe is not welded done properly, it can embrittle connections and even be dangerous.Īs with many things in life, the details are important when welding black pipe. We also offer special pricing for large-scale projects. We offer a wide selection of this material, and you can refine your search by size, method of manufacture, or wall thickness. If you’re looking for black steel pipe, you’ve come to the right place. Hollow structural sections of black steel pipe are ideal for structural applications, such as rebar, girders, and beams. It carries a higher standard for structural applications than ASTM A53 and has been used in many construction applications, including water and gas lines. This specification also covers hot-formed and cold-formed black steel pipes. ASTM A500 specifies dimensions, tolerances, and sectional properties for cold-formed welded structural hollow sections. The smooth, rounded surface and lack of protruding edges make hollow sections ideal for high-profile applications. Its shape is important for many structural applications, including building construction and mechanical manufacturing. For these reasons, black iron pipe is a popular choice for gas lines.Ī hollow structural section of black steel pipe can be either round or square. In fact, black iron is actually made of low-grade mild steel, which makes it more corrosion-resistant. Its compounds and pipe and fittings system allow it to be easily assembled and is relatively easy to repair. Besides its strength, the black iron pipe is also easy to install and maintain. While you may be surprised to know that cast iron pipe is black in the surface and often used for gas lines, you may not know about their difference. ![]() They’re also commonly used for boilers, bearings, and high-precision structural steel pipes. For example, they’re used in boilers and in the petrochemical industry. In addition to gas pipelines, seamless steel carbon pipes are also used in other industries. Carbon steel pipes can be corroded if they are exposed to high temperatures, so you’ll need to choose a different metal for cryogenic liquids. Whether the pipe will be exposed to high temperatures is an important consideration. Choosing the best steel for the job can be tricky, as some materials have more extra properties than others. Other applications may include steam and vent pipes and are used in construction projects. These pipes are often used in municipal and sewage systems. There are many uses for carbon steel pipes. While it can be used for a variety of applications, it is important to keep corrosion in mind. Carbon steel is highly corrosive when exposed to moisture, so it should be handled with care. Actually, black steel is not galvanized and instead has a dark iron oxide coating. Some people are often confused about the difference between black steel pipe and galvanized steel pipe. Here is some commonly used uncoated steel pipe. A lack of protective outer coating may accelerate the need for replacement or rehabilitation. ![]() Pipeline operators must consider the age of these bare pipes when choosing which pipeline materials to use. In addition, black pipes are used by the oil field industry to pipe oil through remote areas. Black steel pipes are especially strong and durable and are used to transport gas and water to rural areas, as well as to protect electrical wiring, deliver high-pressure steam, and carry air. While many of these pipelines have been removed from service and replaced with coated steel or plastic, others are still in operation.īlack steel pipes also known as uncoated steel pipelines. In the case of black pipe, this black oxide scale will not be visible after a few weeks of use. The pipes undergo rigorous testing with water and special X-ray gauges. Modern manufacturing equipment has increased the efficiency and quality control of the manufacturing process. A black steel pipe is a strong piping material with a black iron oxide coating, the dark color is caused by the iron oxide that forms on the steel during the manufacturing process.
