The all flange 45° lateral tee is a crucial branch pipe fitting designed to create a 45-degree angle diversion in water supply, drainage, and industrial fluid transmission networks. With flanged connections on all three ends, this component allows for flexible pipeline branching without the need for complicated on-site cutting or welding.
As part of our ductile iron pipe fitting series, it can be seamlessly paired with dismantling joints, rubber gaskets, manhole covers, and surface boxes, forming a comprehensive support system for underground municipal pipe projects. In the face of increasingly complex urban pipeline planning, this fitting offers a practical solution for engineers to organize pipelines efficiently within limited installation space.
Our all flange 45° lateral tee is made from high-quality GGG500 ductile iron that meets EN1563 standards. This material offers a balance of high tensile strength and excellent shock resistance, preventing cracking under long-term underground loads. After casting, each tee undergoes shot blasting to eliminate surface impurities. We then apply a protective epoxy coating on both the internal and external surfaces, which provides strong resistance against rust, sewage corrosion, and coastal salt fog erosion. Additionally, all flange surfaces are precision machined to ensure a tight fit with rubber gaskets, minimizing the risk of fluid leakage. Products follow international industry standards and support multiple pressure grades to meet different project operating requirements.
The full flanged design stands out as the core advantage of this lateral tee. Compared with welded or socket-type tees, three-way flange connections allow easy disassembly during later inspection and maintenance. Construction crews can quickly connect or separate pipe sections without damaging the main pipeline. The 45-degree angled branch structure smooths fluid flow and avoids sharp turn turbulence, lowering pipeline energy loss and sediment accumulation inside the pipe. This design greatly extends the service life of the whole pipe network. Besides, the symmetrical structural layout improves overall stress distribution, enhancing stability under ground settlement and temperature variation.
This lateral tee is widely adopted in municipal water supply networks, sewage treatment pipelines, residential water distribution systems, industrial circulating water facilities, and fire protection piping projects. It works especially well in compact valve chambers and narrow underground spaces where straight branch layout cannot be realised. When building new pipe networks or carrying out old pipeline renovation, engineers use the all flange 45° lateral tee to adjust pipeline directions flexibly and avoid crossing conflicts with existing cables and pipelines. Combined with supporting pipeline accessories, it helps achieve orderly arrangement inside inspection wells equipped with surface boxes.
Every batch of all flange 45° lateral tees undergoes thorough factory testing before delivery. The inspection process includes checks for dimensional tolerances, coating thickness measurements, hydraulic pressure tightness tests, and appearance quality assessments. We provide comprehensive material test certificates and inspection documents to our overseas customers to facilitate project acceptance and smooth customs clearance. Any defective products are strictly eliminated to ensure that all delivered fittings meet international engineering standards.
Our team offers personalized technical support in addition to custom manufacturing services tailored to meet specific project requirements. Whether clients need modified dimensions, improved anti-corrosion layers, or unique identification markings, we can adjust our production processes to align with local engineering specifications. Each product is meticulously packaged to endure long-distance marine transportation and rough handling. Committed to long-term cooperation with global engineering enterprises, we continue expanding our range of ductile iron pipeline fittings to address diverse challenges in modern municipal and industrial infrastructure construction.
