Applications
- Locations in petrochemical high-pressure process pipelines where bypass or buffer branches need to be led out at an angle.
- In the steam pipe network of a thermal power plant, an inclined branch point is needed for buffering pressure relief and reducing vibration.
- Inclined sampling, blowdown, or instrument monitoring points arranged in coal chemical reaction equipment.
- In high-pressure natural gas pipelines, pipe sections that require vibration damping and flow distribution to avoid excessive vibration in vertical branches.
- For pipelines such as reciprocating pump and compressor outlets where vibration is relatively large and medium scouring is strong, oblique diversion is required to reduce impact.
Overview
The 45° lateral branch outlet is an integrally forged oblique branch fitting, with the branch drawn from the main pipe at a 45° angle, the bottom saddle arc surface welded and fixed to the outer wall of the main pipe, and self-contained equal-area reinforcement. It is mainly used in high-pressure pipelines requiring oblique diversion, buffering, vibration reduction, or inclined instrument points, replacing traditional methods such as 45° lateral tees and on-site oblique hole opening plus reinforcement pads. The branch end can be butt welded, socket welded, or threaded, and it complies with MSS SP-97, ASME B16.9, ASME B16.11, and GB/T19326 standards, with pressure ratings covering 3000LB and 6000LB, main pipe NPS2-NPS48, and branch NPS1/8-NPS4. Material options include carbon steel, low-temperature steel, stainless steel, alloy steel, duplex steel, and nickel-based alloy, suitable for high-pressure pipelines in petrochemical, thermal power, coal chemical, oil and gas, and other industries.
Key Features
Integrally die forged, with no splicing welds, dense and uniform material, suitable for long-term bearing of high-pressure alternating loads. The 45° oblique flow passage transitions smoothly, and compared with a 90° branch outlet it can reduce medium turning vortices, pressure drop, and pipeline vibration. The bottom saddle arc surface fits and welds to the outer wall of the main pipe, with self-contained equal-area reinforcement, requiring no additional reinforcement plate, making construction more space-saving. The branch end provides three connection forms: butt welding, socket welding, and threading, which can be selected according to project requirements. We support customization of non-standard reducing, extended-neck insulation type, thickened high-pressure type, and thread forms such as NPT and BSPT, and can also reverse-customize according to drawings or dismantled parts.
Applications
The 45° lateral branch outlet is suitable for occasions in high-pressure pipelines where an oblique branch needs to be drawn out, such as oblique bypasses of petrochemical high-pressure process pipelines, buffer pressure-relief branches of thermal power plant steam pipe networks, inclined sampling and blowdown points of coal chemical plant equipment, vibration-reducing diversion branches of natural gas high-pressure pipelines, and pipelines such as reciprocating pump and compressor outlets where vibration is relatively large and medium scouring is strong. It is also suitable for pipe racks where pipeline space is limited, oblique avoidance of equipment is required, vertical branch vibration is excessive, or medium scouring is severe. For vertical large-diameter main pipe diversion scenarios, it is recommended to contact us to confirm the selection according to specific working conditions.

FAQs
What is the difference between a 45° lateral branch outlet and a 90° branch outlet?
The main difference lies in the branch outlet angle. The branch of a 45° mitered branch outlet is led out from the main pipe at a 45° oblique angle, and the flow passage transition is smoother. Compared with a 90° branch outlet, it can reduce medium turning vortices, pressure drop, and pipeline vibration, making it suitable for pipelines that require oblique diversion, buffering, or avoiding equipment. The 90° branch outlet is more suitable for vertical branch scenarios. For specific selection, please contact us to confirm.
What working conditions are suitable for selecting a 45° mitered branch outlet?
For high-pressure process pipelines where the pipeline needs oblique avoidance layout, bypass buffering and pressure relief, relatively large pipeline vibration, severe medium erosion, or where flow pattern optimization and noise reduction are required, a 45° mitered branch outlet can be given priority. It is commonly used in oblique bypasses, buffer branches, and inclined instrument points in industries such as petrochemicals, thermal power, coal chemical, and oil and gas.
How to choose among the three connection types: butt welding, socket welding, and threaded?
For permanent oblique main branch connections, butt welding is generally selected; for fixed inclined instrument points, socket welding can be selected; for inclined sampling, drainage, and other points requiring quick installation and quick disassembly, threaded type can be selected. The specific selection needs to be combined with pipeline material, pressure rating, diameter, and construction conditions. You are welcome to contact us to confirm.
Can a 45° mitered branch outlet replace a 45° oblique tee?
In cases where a large pipe is reduced to a small oblique branch and scattered oblique points are involved, a 45° mitered branch outlet can replace a 45° oblique tee, with better flow pattern and more space saving. Whether it is suitable for replacement needs to be confirmed according to the main pipe and branch pipe diameters, pressure rating, and on-site space. Please contact us to provide specific parameters.
What information is required to customize non-standard angles or special materials?
Please provide the main pipe and branch pipe diameters, pressure rating, connection type, material requirements, angle requirements, surface treatment requirements, and quantity. If there are drawings or teardown parts, you can also provide them to us for reverse customization. We will assist in confirming the configuration and quotation based on this information.
