Overview
A branch outlet is an integrally forged reinforced-opening branch extraction fitting used to directly extract a branch line from the outer wall of a main pipe. Compared with traditional reducing tees or the practice of field drilling plus reinforcing pads, a branch outlet does not require cutting the main pipe; its saddle curved surface fits against the outer wall of the main pipe and is then welded, and it has a built-in reinforcement structure that can disperse stress at the opening. The product mainstreamly implements the MSS SP-97 standard, is complemented by ASME B16.9 and ASME B16.11, applies to main pipes from NPS2 to NPS48, branch pipes from NPS1/4 to NPS24, and pressure ratings cover 3000LB and 6000LB. In terms of materials, carbon steel A105, low-temperature steel LF2, stainless steel 304/316L, alloy steel F11/F22, and duplex steel 2205 can be provided; connection forms include butt welding, socket welding, threaded, and 45° miter.
Key Features
The branch outlet is formed by integral die forging, has no spliced welds, and has a dense and uniform material structure. The saddle curved surface fits against the outer wall of the main pipe, and after welding it automatically forms a reinforcement structure, requiring no additional reinforcing pad and no complicated secondary reinforcement process. The internal flow passage is smooth, the medium conveyance resistance is low, and it is not prone to slag accumulation or scaling. For pipeline layouts involving large pipe to small pipe, scattered branch points, and unsuitability for installing traditional tees, the branch outlet can extract a branch without cutting the main pipe and without changing the main pipeline layout. The product can be used long-term in high-temperature and high-pressure, flammable and explosive, strongly corrosive, and other high-risk medium working conditions, and is a commonly used solution for branch connections in petrochemical, power, and oil and gas high-pressure pipelines.
Applications
Branch outlets are mainly oriented toward heavy industrial scenarios involving high temperature and high pressure, large diameter and heavy wall thickness, high-risk media, and precise instrument point extraction. Typical uses include high-pressure main process pipe networks in petroleum refining, long-distance high-pressure natural gas pipelines, high-temperature steam thermal systems in thermal power plants, high-pressure reaction pipelines in coal chemical industries, oil and gas transportation pipe networks on offshore platforms, ultra-high-pressure urban heating main trunk pipelines, and corrosive medium process pipelines in fine chemicals. Specifically, they can be used for extracting instrument impulse lines, sampling lines, drain and vent lines, firefighting branch lines, process branch lines, pressure monitoring interfaces, and bypass circulation lines from process main pipes. It should be noted that branch outlets are not suitable for civil low-pressure water supply and drainage or ordinary light-duty HVAC pipe networks.

FAQ
What advantages do branch outlets have compared with tees?
Branch outlets have a built-in forged reinforcement structure, require no additional reinforcing pad, and are suitable for large pipe to small pipe and scattered point branches. They do not require cutting the main pipe, construction is simpler, stress at the opening is dispersed more evenly, and the overall cost is usually lower than traditional tee solutions, making them a commonly used choice for branch connections in high-pressure pipelines.
How should different types of branch outlets be selected?
For high-temperature and high-pressure main branch connections, welded branch outlets are usually selected; for small-diameter instrument tubing, socket-welded type can be selected; for scenarios such as sampling and blowdown that require quick-install interfaces, threaded type can be selected; for inclined process branches, 45° lateral type can be selected. For specific selection, please contact us and provide the main pipe and branch pipe sizes, pressure rating, medium, and temperature information, and we will assist in confirming.
Can branch outlets be used by directly opening a hole and welding?
Yes. Branch outlets are designed to be welded after directly opening a hole in the outer wall of the main pipe. The saddle curved surface fits the outer wall of the main pipe, and after welding, it has a built-in reinforcement structure. For welding process plans and installation precautions, please contact us to confirm.
