Product Overview
The gradually expanding streamlined branch outlet (Sweepolet) is an integrally forged branch outlet seat product under the Guojie brand, belonging to MSS SP-97 equal-area reinforcement branch outlet seats. Its internal flow channel adopts a circular-arc gradually expanding smooth transition structure, with no right-angle corners from the main pipe to the branch pipe, making the medium turn more smoothly. The saddle surface of the base fits against the outer wall of the straight pipe and is fixed by fillet welding; it is integrally forged and formed with built-in reinforcement, and can replace on-site hole drilling, ordinary branch outlets, and reducing tees. This product is mainly aimed at the branch connection needs of high-speed scouring process pipelines in petrochemical, thermal power, coal chemical, oil and gas, and other industries, and is suitable for projects with control requirements for pressure drop, vortex, scouring wear, and cavitation.
Key Selling Points
First, the flow channel structure is different. The circular-arc gradually expanding streamlined design means there is no right-angle dead corner when the medium enters the branch pipe from the main pipe, which helps reduce vortex, pressure drop, and local scouring stress. Second, the reinforcement method is different. It is integrally forged and formed in one piece, with built-in equal-area reinforcement, conforming to the MSS SP-97 standard, and does not require additional welded reinforcement plates. Third, there are many options for connections and materials. The branch pipe end can be made with three types of connections: butt welding, socket welding, and threaded; material options cover carbon steel, low-temperature steel, stainless steel, alloy steel, duplex steel, and nickel-based alloy, allowing material selection according to the medium and working conditions. Fourth, non-standard customization is supported. It can be custom-made in reverse according to overseas drawings or old imported dismantled pipe fittings, and can also undergo fine-tuning of the streamlined arc, thickening of the body, and special surface treatment.
Applications
This product is suitable for pipeline branch points with requirements for high-speed media, strong scouring, high-frequency alternating, low-noise vibration damping, cavitation prevention, and low pressure drop. Typical scenarios include high-speed process pipeline branches for petrochemical hydrogenation, anti-vibration bypasses at the outlets of reciprocating pumps and compressors, monitoring points for ultra-high-pressure high-speed steam pipelines in thermal power, blowdown branches for high-speed oil and gas gathering and transportation pipelines, branches of fine chemical strong-scouring medium pipeline networks, and long-cycle maintenance-free high-pressure flowline systems for offshore platforms. If in a project the medium flow rate is fast, turbulence is severe, conventional pipe fittings frequently wear through and perforate, pipeline vibration is large, or pressure drop exceeds the standard, the streamlined branch outlet solution can be given priority consideration.

FAQ
What is the difference between a gradually expanding streamlined branch outlet and an ordinary branch outlet?
Ordinary branch outlets mostly have right-angle transitions internally, and when the medium enters the branch from the main pipe, it is easy to form vortices and erosion dead zones. The gradual-expansion streamlined branch outlet adopts an arc gradual-expansion streamlined flow channel, with no right-angle corners from the main pipe to the branch, and the medium turns more smoothly, which helps reduce vortices, pressure drop, erosion wear, and cavitation risk.
What working conditions are suitable for selecting the gradual-expansion streamlined branch outlet?
It is suitable for pipeline branch points with high-speed media, strong erosion, high-frequency alternating conditions, low-noise vibration damping, anti-cavitation, and low pressure drop requirements. For example, compressor or pump outlets, high-speed steam pipelines, high-flow-rate oil and gas pipelines, pipelines prone to erosion wear, process pipe networks with relatively large pipeline vibration, and high-end process systems requiring long-term stable operation.
How to choose among the three connection types: butt welding, socket welding, and threaded?
For high-speed permanent process branches, butt welding is usually selected; for fixed instrument monitoring points on high-speed pipelines, socket welding can be selected; for sampling, drainage, and other points on high-speed pipelines that require quick installation or threaded connection, threaded type can be selected. The specific selection needs to be combined with pipeline design pressure, medium, and connection requirements; please contact us for confirmation.
What standards does the product comply with? What pressure ratings and materials are available?
It complies with MSS SP-97, ASME B16.9, ASME B16.11, and GB/T19326. The pressure ratings are 3000LB and 6000LB. Materials include carbon steel A105, LF2 low-temperature steel, 304/316L stainless steel, F11/F22 alloy steel, 2205 duplex steel, and nickel-based alloy. Main pipe diameters range from NPS2 to NPS48, and branch pipe diameters range from NPS1/8 to NPS4.
