Haihao Group Supplies ASTM A350 LF2 Threaded Branch Fittings to Indonesia
For pipeline projects involving low-temperature service, material selection and connection design have to be considered together. Haihao Group recently completed an order for an Indonesian customer covering ASTM A350 LF2 threaded branch fittings in 1″ and 2″ sizes, both rated at 3000# and manufactured to ANSI B16.11 requirements.
The order uses ASTM A350 LF2 Class 1 material, a forged carbon steel grade commonly selected for applications where toughness and reliable performance at lower temperatures are important. The threaded connection also allows the branch fitting to be installed without a direct butt-welding operation at the branch connection.
Order Details
The shipment includes two sizes of ASTM A350 LF2 threaded branch fittings, both with a 48″ overall length and 3000# pressure rating.
| Product | Size | Pressure Class | Material | Standard |
| Threaded Branch Fitting | 2″ × 48″ | 3000# | ASTM A350 LF2 Class 1 | ANSI B16.11 |
| Threaded Branch Fitting | 1″ × 48″ | 3000# | ASTM A350 LF2 Class 1 | ANSI B16.11 |
Why ASTM A350 LF2 Class 1 Was Selected
ASTM A350 LF2 is a forged carbon steel specification developed for components used in pressure-containing applications where low-temperature toughness is an important consideration. Class 1 is one of the material classes covered by the specification.
For this Indonesian order, the use of ASTM A350 LF2 threaded branch fittings provides a combination of forged construction, pressure capability and material suitability for demanding pipeline service.
The material is particularly relevant to projects where conventional carbon steel grades may not provide the required low-temperature impact performance. This makes LF2 a practical choice for selected oil and gas, petrochemical, power and process piping applications.

3000# Threaded Connection for Branch Piping
The two fittings in this shipment are rated at 3000#, providing a robust connection option for high-pressure branch piping.
A threaded branch fitting is designed to connect a smaller branch line to a larger piping system while maintaining a compact connection arrangement. Compared with a welded branch connection, a threaded design can simplify installation where the project specification permits threaded connections.
For customers sourcing ASTM A350 LF2 threaded branch fittings, the combination of 3000# rating, forged LF2 material and the specified dimensional requirements is an important part of the purchasing specification.
Manufacturing and Quality Control
For forged branch fittings, dimensional accuracy is important because the component must connect correctly with the mating pipe and fitting. Haihao Group pays attention to key parameters such as connection dimensions, overall length, pressure class and material identification during production.
Material traceability is also important for ASTM A350 LF2 threaded branch fittings, particularly when the components are supplied for pressure piping projects. Relevant inspection and documentation can be arranged according to project requirements, including material certificates and dimensional inspection records.
The 1″ and 2″ fittings in this shipment were prepared according to the customer’s specified requirements before being packed for delivery to Indonesia.
Applications of Threaded Branch Fittings
Threaded branch fittings can be used in a range of piping systems where a threaded branch connection is permitted by the applicable engineering specification. Typical applications include:
- Oil and gas piping
- Petrochemical facilities
- Process piping systems
- Utility and auxiliary piping
- Low-temperature service piping
- High-pressure instrument and process connections
The exact application should always be checked against the project’s design pressure, temperature, connection method and applicable piping code.
