API Flanges, Tees and Crosses
API Flanges, Tees, and Crosses are high-quality pipeline components manufactured as per API standards for use in oilfield and industrial applications. They are used to connect pipes, change flow direction, and distribute fluids efficiently. Designed for high-pressure environments, they ensure strength, durability, and leak-proof performance.
Their durability, compliance with industry standards, and reliable performance make them a critical part of modern pipeline infrastructure.
Product Details
API Flanges, Tees, and Crosses are essential piping components manufactured according to American Petroleum Institute (API) standards, ensuring high quality, safety, and reliability in demanding oilfield and industrial applications.
API Flanges are used to connect pipes, valves, and equipment, providing a strong and secure joint that allows easy assembly and maintenance. Tees are designed to split or combine fluid flow in two directions, while Crosses enable flow distribution in four directions, making them ideal for complex piping systems.
Constructed from high-grade forged steel or alloy materials, these components are built to withstand high pressure, extreme temperatures, and harsh operating conditions. Their precision engineering ensures tight, leak-proof connections, reducing the risk of system failure.
Widely used in oil and gas, petrochemical, and energy industries, API Flanges, Tees, and Crosses are available in various sizes, pressure ratings, and configurations to meet diverse operational requirements.
- 6B Weld Neck Flanges: With restricted bores matching standard pipe sizes and schedules.
- 6BX Weld Neck Flanges: Full-bore flanges designed for API 6A service, with no restriction to internal flow.
- Weld neck length can be customized based on client requirements.
- All flanges are supplied with full certification and optional ultrasonic testing.
