When undertaking any construction process, it is crucial to use the correct materials. When the project involves any type of pipe, a decision must be made between welded pipe and seamless pipe. This decision isn't always as simple as it seems.
For example, there are many regulations regarding the use of welded pipe. This is based on the materials passing through the pipe and the pressure those materials will be subjected to. Therefore, it is important to understand seamless steel pipes before making a decision.
Engineering requirements:
High pressure and high temperature environment: For applications that need to withstand high pressure or high temperature, seamless pipes are usually chosen because of their better strength and pressure resistance.
General piping systems: For general piping systems, welded pipe may be a more economical choice because welded pipe is relatively less expensive to produce.
Pipeline usage environment:
Corrosive environments: If the pipe will be used in a corrosive environment, such as in a chemical plant or marine environment, seamless pipes are usually more suitable because they have no welds on their surfaces, reducing the potential for corrosion.
General Environment: In general environments, welded pipe may be a more economical option, but you need to ensure that proper corrosion protection is carried out.
Performance requirements:
Strength and pressure resistance: Seamless pipes usually have higher strength and pressure resistance, and are suitable for high pressure and high temperature conditions.
Cost: If the project has cost budget constraints, welded pipe may be a more economical option.
Pipe diameter and wall thickness:
Diameter and Wall Thickness: For large diameter and wall thickness pipes, seamless pipe is generally easier to produce and performs better at high pressures and temperatures.
Small Diameters and Wall Thicknesses: For pipes with small diameters and relatively thin wall thicknesses, welded pipe may be more economical.
