How to improve the wall thickness accuracy of reinforced 3pe anticorrosive steel pipe
1. For the heating of the tube billet, it is necessary to pay attention to uniform heating, prohibit rapid rise and fall of temperature, and maintain a stable rise and fall of temperature. 2. Use the centering roller to determine whether it is in place, and adjust the center axis and opening angl...Read more -
Anti-corrosion practices of buried steel pipes
Pipeline rust removal→primer coating→full topcoat→second topcoat→winding glass cloth→topcoat→topcoat; Inner wall construction process: pipeline derusting → primer coating → all-over top-coat → second-pass top-coat → third-pass top-coat 1. Pipeline rust removal Before applying the primer, the surf...Read more -
Advantages and disadvantages of ductile iron pipe application
Advantage: Compared with PE pipe, In terms of installation time, ductile pipes are easier and faster to install than PE pipes, and the internal and external bearing pressure is better after installation; From the perspective of airtightness and corrosion resistance, the airtightness of the ductil...Read more -
Spiral steel pipe stacking principle requirements
1. The principal requirement of spiral steel pipe stacking is to stack according to varieties and specifications under the premise of stable stacking and ensuring safety. Different types of materials should be stacked separately to prevent muddling and mutual erosion; 2. It is forbidden to store ...Read more -
Shinestar let you know what are the detection methods of oil casing
1. Ultrasonic testing When ultrasonic waves are disseminated in the detected raw materials, the acoustic properties of the raw materials and the transformation of the internal tissue will have a positive impact on the transmission of ultrasonic waves. After detecting the level and conditions of t...Read more -

What Factors Must be Considered When Designing a Casing/Tubing String
Casing and tubing selection are one of the critical tasks that engineers must carefully decide which type of casing/tubing will be used in the wellbore in order to meet the objective of each well. I would like to share my knowledge about the selection criteria for casing/tubing string design. Oi...Read more -
Understand of Pipe and Piping
Pipe and piping traditionally refer to tubular conveyances used to transmit fluids over long and short distances in a range of industrial, commercial, and residential applications—from gas transmission to sewage. But the term pipe also has a structural meaning in architectural settings, where the...Read more -
Material Compostion of Steel Pipe
1. Carbon (C): increased carbon content in steel, yield points and tensile strength increased, but the plasticity and impact reduction, when the carbon 0.23% over, the steel welding performance deterioration, so for welding Low alloy structural steel, carbon content is generally not more than 0.2...Read more
