Current automated black steel pipe developments tend to be centered on improved seam tracking. Other aspects such as stronger line up clamps have also attracted a lot of attention in the steel pipe market. Most black steel pipe equipment suppliers are taking advantage of increased computing power to improve the arc distance and arc voltage controls. At the same time, laser tracking is also available in steel pipe market. Advanced tracking technology improves black steel pipe quality as well as consistency.

It also improves the production rates by allowing faster travel speeds and the major automated black steel pipe equipment suppliers have realized that. There are now many alternative suppliers of single head orbital machines. Some steel pipes are made from mechanized units and work well with flux cored arc wires. Most of the alternative black steel pipe options for pipeline welding have been examined and evaluated over the past twenty five years. Some of these black steel pipe production methods are pursued, such as laser electron beam and flash butt. While some are working on hybrid laser bugs, the steel pipe market will see a quantum leap in the black steel pipe technology.

If the working surface layers have a high hardness and metal resistance, black steel pipe layered castings can be made on the basis of monolithic inserts. For instance, carbon steel can be poured by liquid cast iron since grey cast iron can be dipped into liquid alloy. On the basis of results of previous studies about black steel pipe, steel plates can be used in direct contact with liquid metal. In some cases, the steel pipe is even covered by activator in form of boron and sodium compounds. These compounds will facilitate the formation of a permanent joint between both materials of black steel pipe layered casting.

The quality of the bimetallic layered casting can be evaluated and steel pipe market also has the option to use tandem arc technology to increase welding speeds. In fact, this technique is especially popular for black steel pipe used in major large diameter pipelines. Automated black steel pipe is tried and tested and future developments will tend to be in more computer control in spite of a progression to robotic automation. On the basis of ultrasonic testing it has been found that only the layered casting can be made at pouring temperature. Thus the concentration of carbon in black steel pipe might be lowered in the permanent joint as the bottom echo is larger than that of the transition zone. Moreover, twenty percent of the steel pipe market is characterized by bimetallic connecting bridges. They also provide stability of joint and do not significantly reduce the application characteristics of steel pipes.
