High Pressure & Moderate Temp EFW Pipes

Product Introduction

High Pressure & Moderate Temp EFW Pipes are welded steel pipes. Welded steel pipes refer to steel pipes with seams on the surface that are welded after bending and deforming steel strips or steel plates into round or square shapes. The billet used for High Pressure & Moderate Temp EFW Pipes is steel plate or strip steel. Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes.

When using High pressure & moderate temp EFW pipes, it's important to clearly define the project scopes for "high-pressure" and "medium-temperature" to avoid confusion with "low-pressure, normal-temperature" or "high-temperature, high-pressure" piping.

High pressure: Generally, pressures between 10MPa and 100MPa are considered high pressure. High-pressure environments require the pipe to withstand high static pressure from the fluid.

Medium temperature: Temperatures between -40°C and 400°C are considered medium temperature, emphasizing both low-temperature toughness and medium-temperature stability. Operating environments do not involve ultra-low temperatures or high temperatures.

Electrofusion welding: During production, welds undergo 100% non-destructive testing to ensure equal strength and toughness to the parent material, distinguishing them from high-frequency resistance welding.

The core technology of high pressure & moderate temp EFW pipes lies in achieving high-pressure bearing capacity through electric fusion welding, while balancing medium-temperature stability through material optimization and heat treatment. It is a key application in the oil, gas, and chemical industries. With the advancement of global energy infrastructure, demand is growing, and we are constantly innovating in our production processes.

Advantages

High Pressure & Moderate Temp EFW Pipes can be used to translate high-pressure oil and gas.

Longitudinal welded pipe production process is simple and high production efficiency. Welded steel pipe has strong corrosion resistance in acidic environment. With the advancement of welding and inspection technology, the quality of welds continues to improve,and the variety of pipes are increasing.
