Welded Steel Pipes for Underwater Applications

Welded steel pipes used in underwater applications need to withstand extreme pressures and corrosive environments, especially in offshore oil and gas exploration.

• Corrosion Resistance: Welded pipes for underwater use must be made from corrosion-resistant materials or coated with protective layers like epoxy, to withstand saltwater corrosion.

• Pressure Handling: These pipes are subjected to very high pressure and must be designed with thick walls to prevent deformation or failure.

• Welding Techniques: Specialized underwater welding techniques are required for repairs and maintenance, such as wet welding or dry welding.

• Fatigue Resistance: Pipes in underwater applications must resist cyclic loading caused by waves and currents.

The performance of welded steel pipes in underwater applications is critical to ensuring the integrity of pipelines used in offshore drilling, transportation, and deep-sea infrastructure.
