Why are seamless steel tubes perforated

　　There is visible sign for seamless steel pipe and welded one even you are just a fresh for those steel pipes. You would call it seamless one once you see there is no crack in the surface. Here is the question: why we adopt the perforation process for seamless steel pipe?

　　The first concern is, of course, its function. As we all know, seamless steel pipe would be the best partner for transmitting the high pressure medium. They can be oil, gas, and water. And the main purpose for the perforation process is here. First of all, it would make a solid round billet piercing hollow shell. And seamless steel pipe, produced by perforation process, would meet the requirement of accuracy, surface quality, specifications and so on. What’s more, once the steel pipe transports the dangerous products, they are not just produced for safety, but for lots of aspects’ reasons.

Xinyue supports pressure piping projects for regular customers

Project location：Middle East Product：Spools (Short pipes&fittings welded with double flanges) Specifications：OD 114-813MM, WT 6-17MM, L 800-4200MM Standard and material：Pipes in ASTM A53 GRB; Fittings in B16.9 ASTM A234 WPB; Flanges in EN1092-1 ASTM A105; Welded in standard API 1104 Hydro test in EN13480-5 Usage：Pressure Liquid Pipeline project Inquiry time：2022.03.02 Order time：2022.07.20 Shipping time：2022.09.22 Estimated arrival time：2022.10.28 This order is still from a regular client. The client has been purchasing SMLS&LSAW&SSAW steel pipes from Xinyue for 4 years. After reading the project list and spool project supply record of Xinyue, the customer knew that Xinyue had its own welding and coating processing line this year, so he immediately sent an inquiry to Xinyue after having an spool inquiry. As expected, Xinyue gave the customer the best price and shipping schedule solution, and made 13 sets of drawings for customers and terminals to refer to. With the help of ...

The Difference between Mechanical and Structural Steel Tube

    Steel tube is used in a variety of structural and industrial applications, such as automobile transport, architecture, and construction. These steel tubes are made of different steel structures, from stainless steel, carbon, zinc or soft steel, depending on the application requirements.     Steel tubing is divided into two classes: mechanical and structural, depending on its design. So what is the difference between mechanical and structural steel tube? Below are some points to consider while differentiating the two types of steel tubing. The comparison is made on the basis of application, specification, and shape.     Comparison between mechanical and structural steel tube     Application: Mechanical tubing is used in low stress and light gauge structural applications. These applications include conveyor belt components, solar panel supports, greenhouse structures, kitchens and restaurants, hospitals and medical equipment, and various t...

Methods for non-destructive testing of seamless steel tubes

 Non-destructive testing refers to the inspection methods used to inspect the internal or surface defects of the material, or to determine some physical quantities, properties, and organizational states of the material without destroying the original state and chemical properties of the material to be tested. There are four commonly used non-destructive testing methods for seamless tubes: 1. X-ray inspection Suitable for detecting internal defects in metals, non-metals or other materials. The energy of the light quantum of X-ray is much greater than that of visible light, it can penetrate objects that visible light cannot penetrate, and while penetrating objects, it will have complex physical and chemical interactions with matter, which can ionize atoms and cause certain substances to emit light. Fluorescence can also cause photochemical reactions in certain substances. If there is a defect in the local area of the workpiece, it will change the attenuation of the object to the ray ...
