Overview of Welded Steel Pipe

Welded steel pipes are made by rolling a metal sheet into a round shape. Then, the edges are welded together. These pipes are known for their strong structure, flexibility, and low cost. They have even wall thickness, smooth inside surfaces, and great strength. This makes them perfect for many uses. The welded roll-formed pipe is sturdy. It also helps save steel and reduces building work.

Common Applications of Welded Pipes

Furniture Manufacturing

Welded steel pipes are often used in furniture making. They are light but tough. These pipes form the base for chairs, tables, bed frames, and other furniture pieces.

Oil and Gas Pipelines

In the oil and gas industry, these pipes move crude oil, natural gas, and refined products over long distances. They work well because they can handle high pressure. This makes them vital for this field.

Fuel Lines and Automotive Uses

Car industries use welded steel pipes for fuel lines, exhaust systems, and structural parts. Their resistance to rust and strong weight-to-strength ratio improve vehicle performance and lifespan.

What Is a Welded Pipe Roll Forming Machine?

Description and Functionality of the Machine

A Welded Pipe Roll Forming Machine is a special tool designed to make steel pipes in a continuous process. It rolls metal sheets into round shapes. Then, it welds the edges to create pipes. This machine is key for industries needing top-quality pipes with exact sizes.

Key Components Overview

Decoiler Unit

The decoiler unit holds the raw material coil. It feeds the material into the machine. This ensures smooth unrolling during production.

Roll Forming System

This part shapes the flat metal sheet into a round form. It uses multiple rollers. These rollers are carefully designed to keep pipe sizes consistent.

Welding Section

The welding section joins the edges of the rolled sheet. It uses methods like high-frequency welding or TIG welding. Gas Tungsten Arc Welding (GTAW) or TIG Welding is a joining process used on stainless steel.

Cutting Mechanism

After shaping and welding, the cutting mechanism trims the pipe to set lengths. It uses hydraulic or servo-driven cutting systems.

Production Process of Welded Pipe

Slitting Process for Raw Materials

Production starts with cutting wide steel coils into narrow strips. These strips are suitable for pipe shaping. This step ensures accurate width alignment for smooth production.

Uncoiling the Steel Strips

The decoiler unrolls the cut steel strips onto a feeding platform. Proper tension control prevents material damage during this stage.

Forming the Pipe Shape

The roll forming system slowly bends the flat strip into a round shape. It uses multiple roller stations. The Welded Pipe Roll Forming Machine is special equipment for continuous rolling and cold-forming on steel sheets.

Welding Techniques in Pipe Production

High-Frequency Welding Overview

High-frequency welding uses electric currents to heat and join metal edges. It does not need extra filler materials. This method is great for making strong seams quickly.

Welding Process for Pipes

During welding, the edges are aligned precisely. This ensures even seam quality. An arc welding process or TIG welding for stainless steel heats the metal. Argon gas protects the weld area from air contaminants.

Sizing the Final Product Dimensions

After welding, sizing rollers adjust the pipe’s diameter to meet exact standards. This step ensures all pipes are consistent.

Cutting to Desired Lengths

Finally, servo-driven cutting systems slice the pipes into needed lengths. They create minimal waste. Servo tracking cutting saws are used for accurate cutting.
