SMLS pipes, ERW pipes, LSAW pipes, SSAW pipes, and DSAW pipes are several critically important types of tubing in industrial production, widely used across sectors such as energy transportation, petroleum refining, and construction engineering. While these pipes share many similarities, they exhibit significant differences in application domains, specification ranges, mechanical strength, and manufacturing processes. This article provides a detailed analysis of their characteristics, advantages, and suitable usage scenarios to serve as an effective procurement guide.

Carbon steel pipes are a highly common type of piping material, widely used across numerous fields such as energy transmission, mechanical manufacturing, and construction engineering. Compared to other piping materials, carbon steel pipes offer advantages including high strength, resistance to high temperatures and pressures, and low cost. This article will provide an in-depth analysis of the strengths and weaknesses of carbon steel pipes, offering you an effective purchasing guide for carbon steel pipes.

Outer diameter dimensions and wall thickness are critical factors affecting the performance and applicability of tubing. As a professional steel pipe supplier and manufacturer, we are committed to providing customers with accurate and reliable product information to meet diverse industrial requirements. This article will focus on the outer diameter dimensions and wall thickness standards for American Standard pipes, offering you clear reference guidelines. Through an in-depth analysis of these standards, we aim to assist you in making more precise decisions when selecting and procuring steel pipes.

We have compiled a stainless steel standard comparison chart to help you clearly compare standards across different countries, enabling you to make more informed decisions when selecting materials.

In diverse application scenarios and operating conditions, the selection of piping materials is critical to structural strength and project durability. Black iron pipes and black steel pipes are two of the most common types of piping, widely used in various engineering projects. Despite their similar names, they differ in material composition, intended applications, and performance characteristics. This article will explore the definitions and properties of black iron pipes and black steel pipes, providing a comprehensive comparison between them.

In the global steel pipe industry, China has emerged as the world’s largest producer and exporter of steel pipes, leveraging consistent quality, competitive pricing, and extensive product offerings. According to statistics, China’s annual steel pipe production exceeded 1 billion tons by 2024. Chinese steel pipe manufacturers not only meet domestic demand but also supply premium products to international markets. This article highlights China’s top five leading steel pipe manufacturers and suppliers, focusing on their technological advantages, production capacity, and product ranges.

In steel pipe specifications and dimensions, Schedule (SCH) denotes the pipe wall thickness, serving as a key factor in determining the pipe’s pressure rating and strength. A higher Schedule number indicates thicker pipe walls and greater pressure-bearing capacity.

This document contains weight tables for API 5L/ASTM SCH 40 and SCH 80 pipes, enabling you to locate the corresponding pipe weight for each specification. We also provide weight calculation formulas, fundamental parameters, and material density coefficients. By studying these resources, you can easily calculate the weight of pipes made from various materials such as carbon steel, stainless steel, and PVC.
