Understanding Pipe Scheduling: SCH 40 & SCH 80

Pipe schedules show wall thickness and pressure limits. Each number represents a specific wall thickness. Engineers use these numbers to design safe and efficient piping systems. Schedule 40 has thinner walls than Schedule 80. It suits systems with moderate pressure. Schedule 80 walls are thicker... Read More

Differences Between ERW Pipe and DOM Pipe

Pipes play a vital role in industrial systems. They transport liquids and gases and support mechanical structures. Industries such as oil and gas, construction, and equipment manufacturing rely on them daily. Manufacturers use different production methods. These methods create differences in pipe... Read More
