Detailed Introduction
TOL threaded branch outlet (Threadolet) is formed by integral die forging, with the saddle arc surface at the bottom welded and fixed to the outer wall of the main pipe, and the upper end has built-in NPT or BSPT tapered pipe threads, so branch pipes and instrument valves can be directly connected by threads without the need for on-site secondary welding. Pressure ratings cover 3000LB and 6000LB, main pipe from NPS2 to NPS48, branch from NPS1/8 to NPS4. Materials include carbon steel A105, low-temperature steel LF2, stainless steel 304/316L, alloy steel F11/F22, and duplex steel. It is mainly used for leading out small-diameter functional points such as pressure gauge connections, drain and vent, and online sampling on high-pressure pipelines, and is suitable for pipe rack environments that require frequent disassembly and assembly of instruments and have compact space.

| Packaging | Our factory's TOL threaded branch outlets, as precision high-pressure threaded forged pipe fittings, adopt foreign-trade heavy-industry-grade refined protective export packaging, focusing on protecting precision thread profiles, saddle fitting arc surfaces, and machined end faces, preventing transportation impacts, thread stripping, corrosion, deformation, and dust ingress blocking holes. All products undergo professional anti-rust treatment before leaving the factory. Carbon steel parts are sprayed with long-acting industrial anti-rust oil, sealing the metal surface to isolate oxidation and corrosion; stainless steel parts undergo pickling and passivation and deoxidation treatment, adapting to ocean shipping salt-spray humid environments. All threaded ports are equipped with special plastic thread protectors, comprehensively protecting precision thread profiles from wear, deformation, and thread jamming; the bottom arc surface is affixed with shock-absorbing protective rubber pads to avoid wear on the fitting surface affecting welding precision. Each piece is individually wrapped in thickened bubble wrap and pearl cotton for all-around protection |

Applications
- Threaded interface lead-out for pressure gauges and pressure transmitters on petrochemical high-pressure process pipelines
- Branch connection for blowdown and vent points on steam pipe networks in thermal power plants
- Rapid deployment of online sampling ports for coal chemical reactor units
- Addition of pressure relief branches or instrument monitoring points on high-pressure natural gas pipelines
- Micro branch renovation of old pipelines, enabling lead-out of threaded functional ports without cutting off the main pipe
Overview
TOL threaded branch outlet is an integrally forged 90° internally threaded branch pipe fitting. The bottom saddle arc surface is welded to the outer wall of the main pipe, and the upper end has a built-in tapered pipe thread, used to lead out small-diameter functional points on high-pressure pipelines. Branch pipes and instrument valves can be directly screwed on without secondary welding, suitable for pipe gallery environments requiring frequent instrument disassembly and assembly and with compact space. It complies with MSS SP-97, ASME B16.11, and GB/T19326 standards. Pressure ratings cover 3000LB and 6000LB, main pipe from NPS2 to NPS48, and branch pipe from NPS1/8 to NPS4.
Key Features
Integrally die-forged and formed, with no spliced weld seams, dense and uniform material, and structural strength higher than welded spliced pipe fittings. The upper end tapered thread is highly precise, allowing instrument valves to be directly screwed on, eliminating hot work construction and making disassembly and assembly convenient. The saddle arc surface precisely fits the outer wall of the main pipe, dispersing stress after welding, conforming to equal-area reinforcement specifications such as MSS SP-97, with no need for additional reinforcement plates. Thread types support NPT, BSPT, and RC, and non-standard thread profiles can be customized to adapt to instrument interfaces of various countries. Mainstream specifications in carbon steel and stainless steel are kept in regular stock, and regular orders are shipped within 24 hours.
Applications
Mainly used for pressure gauge interfaces on high-pressure process pipelines in petrochemicals, vent and drain points on steam pipe networks in thermal power plants, online sampling interfaces on reaction units in coal chemical industries, pressure relief branches on high-pressure natural gas pipelines, and miniature branches for temperature and pressure measurement in industrial units. Suitable for high-pressure pipe gallery scenarios with large main pipe diameters, small branch diameters, scattered and dense points, and the need for regular disassembly, assembly, and maintenance.

FAQ
What is the core advantage of TOL threaded branch outlets?
Integral forging provides built-in reinforcement, and the upper end tapered thread can directly screw onto instrument valves, eliminating secondary welding, making disassembly and assembly convenient, occupying little space, and making it suitable for high-pressure miniature functional points.
How are TOL, SOL, and WOL distinguished?
For applications requiring frequent instrument disassembly and assembly and pursuit of rapid maintenance, choose TOL threaded type; for dense fixed instrument points, choose SOL socket weld type; for high-temperature and high-pressure permanent main branch connections, choose WOL butt weld type.
What are the commonly used thread standards?
The mainstream in foreign trade are NPT American tapered thread and BSPT British tapered thread; RC pipe thread and other non-standard thread profiles can also be customized. Please contact us to confirm the specific standard.
What is the pressure adaptation range?
3000LB is suitable for conventional high pressure, and 6000LB is suitable for thickened ultra-high pressure. The specific selection needs to be confirmed according to the main pipe wall thickness, medium, and working conditions. You are welcome to contact us for assistance.
Is non-standard customization supported?
We support customization such as non-standard reducing, extended neck, special thread profiles, special materials, and surface treatment. Please provide drawings or samples, and we can reverse-engineer a one-to-one custom match.
