Difference between Structural and Fluid Seamless Steel Pipe

Structural seamless steel pipes are used for the processing and use of mechanical structures. The representative materials of structural seamless steel pipes are carbon steel 20, 45#, alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.



The application of fluid seamless steel pipe is for fluid transportation. In terms of manufacturing, domestic steel pipes are made of 10#, 20# carbon steel hot-rolled pipes or cold-drawn pipes.


The difference between fluid seamless pipe and structural seamless pipe is that the fluid seamless pipe needs to do hydraulic experiments one by one or do ultrasonic, eddy current, and magnetic flux leakage flaw detection. Therefore, in the standard selection of pressure pipeline steel pipes, it is more suitable to use fluid seamless steel pipes.

The Method of Extending the Service Life of Seamless Pipe

图片
Seamless steel pipes   have hollow sections and are widely used as pipes for conveying fluids, such as pipes for conveying oil, natural gas, gas, water and certain solid materials. The seamless pipe has a certain corrosion resistance, but in order to prolong the service life of the seamless pipe in some extreme environments, it is necessary to remove the oxide layer on the surface of the product. The main cleaning method is pickling. After cleaning, electrolytic cleaning is required again. 1. The seamless steel pipe must wear labor protection supplies before pickling. The on-site working environment should also be checked in detail, mainly to check whether the hoisting of the steel pipe is intact, and work can only be carried out after confirming that it is intact. 2. When pickling seamless steel pipes, the pickling method is mainly hydrochloric acid pickling. Usually, the content of hydrochloric acid is preferably 18% to 20%. 3. The staff also need to know the concentration and temper

Methods of Connecting Spiral Pipes

图片
The most commonly used method of connecting   large-diameter spiral steel pipes   is welding. However, manufacturers also use threaded connections, flange connections, socket connections, and groove connections in projects. In the post,   Xiangjiasteel   would like to introduce you some details about three main connections. 1. Welding and Flange Connection Welding and flange connections are traditional methods of connecting spiral pipes. These methods do not fully meet market demands in terms of safety, sealing performance, cost efficiency, and repair efficiency. They are mainly used for water transmission pipelines, oil and gas pipelines, chemical pipelines, and power pipelines. 2. Clamp Fitting Connection Clamp fitting connections are an advanced method of pipe connections. They can be used for both exposed and buried installations, accommodating both rigid and flexible joints.  3. Groove Fitting Connection Groove fitting connections, also known as clamp connections, have become the

Exploring the Importance of Drill Pipe

图片
Oil Country Tubular Goods   (OCTG) are vital components in oil and gas drilling activities. The term OCTG refers to a range of piping products specifically designed for use in the production of oil and gas. These products include drill pipes, casing pipes, tubing pipes, couplings, connections, and accessories. In this article, we will focus on the significance of drill pipes, one of the three main types of OCTG pipes. A drill pipe is a robust, seamless tube that serves a crucial role in drilling operations. It facilitates the rotation of the drill bit and allows the circulation of drilling fluid. This fluid helps in pumping through the drill bit and flowing back up the annulus, the space between the casing and the piping. The Importance of Drill Pipe in OCTG Endeavors: Drill pipes are designed to withstand axial tension, high torque, and internal pressure. Their strength and durability make them indispensable in the oil and gas industry. Here are some key reasons why drill pipes are cr
