Q:What LSAW pipe diameters, walls & grades do you offer?

A frequent and essential question we receive from project planners and engineers relates to the specific manufacturing capabilities of our LSAW pipe mills. Understanding these parameters is key to aligning our production strengths with your project’s unique engineering and design requirements.

At Allland Steel, our significant investment in modern JCOE (J-ing, C-ing, O-ing, Expanding) manufacturing technology allows us to produce a comprehensive range of high-specification LSAW pipes. Below is a detailed outline of our standard production capabilities.

Core Production Capability Overview

It’s important to view this data as a general guide to our capabilities. We often have the flexibility to produce non-standard or custom dimensions to meet specific project demands.

Parameter	Specification Range	Notes
Outer Diameter (OD)	406.4 mm – 1524 mm (16″ – 60″)	Continuous range available.
Wall Thickness (WT)	6.0 mm – 60.0 mm (1/4″ – 3″)	Heavy-wall capability is a key strength.
Length	3.0 m – 12.5 m (10” – 40”)	Can be customized based on project needs.
Steel Standards	API、ISO、EN、ASTM、DIN、JIS、GB、CSA、GOST	Comprehensive international standard compliance.

Beyond the Numbers: What Our Capabilities Mean for Your Project

While the figures provide a technical summary, the real value lies in what they enable you to achieve.

Large Diameter and Heavy Wall Thickness

Our ability to produce pipes with substantial diameters and heavy wall thicknesses is critical for projects where high pressure and significant external loads are primary design concerns. This makes our LSAW pipes the ideal solution for:

• High-pressure natural gas transmission mainlines.
• Deepwater and offshore pipelines.
• Large-scale structural components for bridges, stadiums, and offshore platforms.

High-Grade Steel (Up to X70)

From a project economics perspective, utilizing high-grade steel like API 5L X70 can lead to significant advantages. A higher-grade material allows for a reduced wall thickness while maintaining the same pressure rating. This results in:

• A lighter pipe, reducing material tonnage and cost.
• Lower transportation and handling expenses.
• Reduced welding time and material consumption on site.

A core principle at Allland Steel is that our quality control standards are absolute. Every pipe, regardless of its dimensions or steel grade, undergoes the same rigorous inspection and testing regimen, including hydrostatic testing and 100% NDT on the weld seam.
