How to Select Mechanically Lined Pipe

  The Art of Picking Mechanically Lined Pipe: What They Don’t Tell You in the Brochures Look, I’ve been in this game for 22 years. Started as a shop floor inspector back in ’02, worked my way up through quality control, spent a decade in failure analysis, and now I’m the guy they call when

Lined Steel Pipe Selection Guide: How to Choose the Right Lining Material

The Liner Decision: Thirty Years of Matching Plastic to Poison You ever seen what sour gas does to carbon steel? I have. It’s not pretty. The steel doesn’t rust like it does in air. It cracks. From the inside out. Little lines that you can’t see until the day they reach the outside and everything

Microstructural Characteristics of Bimetallic Composite Steel Pipe Interfaces and Welds

Microstructural Characteristics of Bimetallic Composite Steel Pipe Interfaces and Welds: A Field Engineer’s Perspective Introduction: Why I Still Care About Interfaces After 22 Years Look, I’ve been doing this since 2003. Started as a junior site engineer on a pipeline project in the Kazakh sector of the Caspian region—minus forty in winter, and the wind

Research on Inner Clad or Lined Alloy Composite Steel Pipes

Research on Inner Clad or Lined Corrosion-Resistant Alloy Composite Steel Pipes for Oil and Gas Industry Introduction: With the continuous deepening of China’s oil and gas exploration and development strategy, the exploitation scope has gradually expanded to deep-sea, deep-layer and high-sulfur areas, and the operating conditions of oil and gas pipelines have become increasingly harsh.

Analysis of API 5L X70Q / L485Q Seamless Pipeline Steel

Microstructure and Mechanical Properties Analysis of API 5L X70Q / L485Q Seamless Pipeline Steel Abstract: API 5L X70Q/L485Q seamless pipeline steel is widely used in the construction of long-distance oil and gas transmission pipelines due to its excellent low-temperature toughness, high strength, and corrosion resistance. In this paper, a comprehensive analysis of the microstructure and

Low-Carbon Steel-Stainless Steel Composite Pipes Welding Process

Welding Process for Small-Diameter Low-Carbon Steel-Stainless Steel Composite Pipes The following analysis provides a comprehensive, scientific, and data-driven discussion of the welding process for small-diameter low-carbon steel-stainless steel composite pipes, based on the referenced study (DOI: 10.7512/j.issn.1001-2303.2023.05.12). The content covers material properties, welding techniques, quality control, and comparative analysis, supported by tables for clarity. 1.

Understanding Schedule and Wall Thickness in Stainless Steel Forged Flanges

Difference Between Schedule and Wall Thickness in Stainless Steel Forged Flanges The difference between schedule and wall thickness in stainless steel forged flanges lies in their definitions, usage, and how they relate to pipe and flange dimensions. Below is a detailed, scientific, and data-supported explanation, including comparisons and tables to clarify these concepts. 1. Definition

Composite Steel Pipe Research

Research on Wear-Resistant Steel for Wear Layer of Composite Steel Pipes Wear-resistant composite steel pipes are widely used in industries such as mining, power generation, cement production, and metallurgy, where the transportation of abrasive materials causes significant wear on pipelines. These pipes typically consist of an outer steel layer for structural strength and an inner

There is scientific knowledge about clad pipe

First, the user wants the specification of cladded pipes. I should mention standards like API 5LD, ASTM A265, and maybe NACE MR0175 for sour service. Include parameters like dimensions, materials, pressure ratings, and testing requirements. Next, the cladding process. I know there are methods like explosive bonding, roll bonding, weld overlay, and co-extrusion. Need to

Difference Between Weld Overlay & Cladding

First, I need to clarify if weld overlay is a type of cladding. From what I remember, cladding is a broader term that includes various techniques to bond a CRA layer to the base material. Weld overlay is one of those techniques. So, the main difference would be that cladding is a category, and weld
