API 5l X46 Pipe

Description

Product Description API 5l X46 Pipe

The API 5L X46 Pipe is a high-quality, versatile product widely used in the oil and gas industry. This pipe is designed to meet the requirements of API (American Petroleum Institute) specifications, ensuring reliable performance under demanding conditions. Its robust construction and superior mechanical properties make it a preferred choice for the transportation of oil, gas, and water in both onshore and offshore pipelines. These pipes are available in two product specifications: PSL1 and PSL2. While PSL1 is the normal quality level, PSL2 provides improved chemical and mechanical qualities for more demanding applications.

API 5L X46 pipes are available in seamless and welded forms, offering flexibility for various project requirements. Seamless pipes are ideal for high-pressure applications, whereas welded pipes are more cost-effective for low- and medium-pressure uses. They also come in a range of dimensions, lengths, and coatings to suit diverse operational needs.

These pipes are known for their excellent resistance to corrosion, high temperature, and harsh environments, ensuring long-lasting performance. Common applications include natural gas pipelines, crude oil transport, and water distribution systems.

In addition to their technical advantages, API 5L X46 pipes comply with stringent international standards, making them a reliable and sustainable choice for global industries. Their versatility, durability, and high performance underline their importance in critical infrastructure projects.

Notes

• OD (Outside Diameter): Measured from the outer edges of the pipe.
• Wall Thickness (WT): Based on Schedule 40 for standard weights. Heavier or lighter schedules (e.g., SCH 10, SCH 80) are available.
• Weight per foot: Calculated approximately using the steel density of 490 lbs/ft³.
