Branch pieces Manufacturers online

Branch pieces are fittings that make it possible to branch a main line into one or more secondary lines.

They form connection points at which the medium (e.g. water, gas, oil, air) is routed in a controlled manner in a different direction or to other consumers.

Below you will find how they work, the materials and designs, special variants of branch pieces, their use and the advantages and challenges they present:

Functionality of branch pieces:

The basic function of a pipe branch piece is to divide or divert the volume flow of a medium. To do this, the component has several openings that are connected to each other:

1. T-piece: Main pipe with a 90° branch. Standard solution in many systems.
2. Y-piece: Branch at a more acute angle to reduce flow losses.
3. Cross piece: Four connections in the shape of a cross, rarely used, e.g. in special distribution networks.

In terms of flow technology, the design is such that pressure losses and turbulence are kept to a minimum. Good branch pieces therefore have rounded transitions and are shaped in such a way that they prevent stalling.

The branch direction and angle are crucial: a 90° branch can cause greater flow changes and pressure losses than a gentle Y-branch.

Materials and designs of branch pieces:

Branch pieces are made from a wide variety of materials, depending on the medium and the operating conditions:

1. Metals: steel, stainless steel, copper or brass.
2. Plastics: PVC, PE, PP are corrosion-resistant, chemical-resistant and lightweight.
3. Cast iron: Often used in water pipe construction.
4. Composite materials: Combinations of different materials for special requirements.

The connection technology depends on the pipe system:

1. Welded or soldered connections.
2. Threaded connections
3. Flanges
4. Press, plug or clamp connections

Special variants of branch pieces:

In addition to the classic T- and Y-pieces, there are also special branch pieces:

1. Reduced branch pieces that allow a branch with a smaller diameter.
2. Reinforced or braced shapes for high pressure.
3. Flexible branches, for example for plastic hoses.
4. Multiple distributors that offer several outlets at the same time.
5. Sanitary-specific shapes, e.g. branches with cleaning openings or non-return valves.

Use of branch pieces:

Branch pieces are indispensable elements in practically all piping systems and are used to branch networks, enable distributions or connect consumers. Typical applications are

1. Drinking water and waste water networks:
Branching to households or parts of buildings.

2. Heating and cooling technology:
Distribution of supply and return lines to several radiators or cooling zones.

3. Industrial plants:
Process lines for chemicals, steam or gases.

4. Compressed air networks:
Connection of several tools or machines to a central line.

5. oil and gas pipes:
Branches to distribution points or measuring stations.

6. Irrigation systems:
Distribution of the water flow to several fields or sprinklers.

7. Laboratory and medical technology:
Branching of gas or liquid lines into precise controls.

Advantages of branch pieces:

• Flexibility in planning: simple branching of networks.
• Cost efficiency: Less expensive and space-saving than separate distribution boxes.
• Variety of materials and sizes: Adaptable to almost any application.
• Simple installation: Can be installed quickly and safely depending on the connection technology.

Challenges of branch pieces:

• Flow losses: Branches can generate pressure losses and turbulence.
• Risk of blockage: The shape must be selected correctly, especially in wastewater pipes.
• Material compatibility: Must match the medium and the rest of the piping.
• Standards and approvals: Strict rules apply for drinking water or gas.

Branch pieces are elementary components in piping technology. They enable the distribution of media in branched networks and are available in countless variants, materials and connection technologies. The right choice ensures efficient, safe and long-lasting operation of pipe systems in homes, industry and infrastructure.

Below you will find an overview of the most important criteria that you should pay attention to when purchasing branch pieces:

Before purchasing branch pieces, you should ensure that the size, shape, material and connection technology match the pipe system and medium and meet the necessary pressure, temperature and standard requirements. Attention should also be paid to quality, approvals and availability for a safe, long-lasting installation.

• The most important basis for the purchase is the correct dimensions of the branch piece:
• The branch piece must match the pipe diameters and connection types of the planned pipe - including the main and branch connection. Branches can have the same or reduced diameters. Incorrect dimensions lead to installation problems or leaks.
• The choice of the right shape depends heavily on the application:
• T-pieces are standard for simple 90° branches.
• Y-pieces are more flow-friendly and are preferred when pressure losses or turbulence need to be minimized.
• Cross pieces are used for distribution points with four outlets, but they are less common and must be planned with care.
• Reduced branches allow different diameters on the main and branch sides.
• Depending on the flow, medium and space conditions, the appropriate geometry should be carefully selected.
• The material must be compatible with the pumped medium and withstand the ambient conditions:
• For drinking water, corrosion-free materials such as stainless steel or approved plastics are required.
• Steel, stainless steel, copper or pressfitting material is often used for heating systems.
• Chemical-resistant plastics or special alloys are required for chemical pipes.
• The temperature and pressure resistance of the material must correspond to the operating conditions.
• The wrong choice of material can lead to corrosion, leaks or even dangerous leaks.
• The type of pipe connection determines which branch piece is required:
• Weldable variants for metal pipes in industrial applications.
• Threaded connections for simple installations or repairs.
• Press, push-fit or compression fittings for modern building technology.
• Flanged versions for systems with high pressures and for ease of maintenance.
• The selected connection technology should be compatible with the rest of the pipe system and correspond to the installation conditions on site.
• Professional systems often have high operating pressures or temperatures. Branching pieces must be approved for this.
• Important points here are:
• Maximum permissible operating pressure (PN classes)
• Temperature range (hot water, steam, cold)
• Safety margins according to standard or operating guidelines
• Undersized branch pieces can fail and cause massive damage.
• Certified and standard-compliant components are mandatory in professional applications. Among other things, the following must be observed:
• DIN, EN or ASME standards for dimensions and pressure ratings.
• DVGW approvals for drinking water installations.
• PED (Pressure Equipment Directive) for pressure systems.
• Hygienic requirements for food or pharmaceutical lines
• Certified quality avoids liability risks and ensures operational safety.
• Professional purchasing takes into account not only the geometry, but also the influence on the flow:
• Avoidance of pressure losses and turbulence.
• Branch angles suitable for the medium and speed.
• Flow-optimized shapes reduce energy losses and operating noise.
• In pump or high-pressure systems in particular, an incorrect branch piece can drastically reduce efficiency.
• Professional installations are designed for long operating times. The following points should be taken into account when making a selection:
• High-quality materials and precise workmanship.
• Corrosion protection, e.g. by using coated or stainless variants.
• Possibility of easy disassembly, e.g. flange solutions or press connections.
• Availability of spare parts or compatible system components
• Availability must be guaranteed, especially for large projects. Questions that arise:
• Is the required size and material version immediately available from stock?
• Are large quantities also available?
• What are the delivery times for special sizes or materials?
• Planning reliability is crucial to avoid construction site delays.
• A high-quality branch piece can save costs for years, while a cheap part often quickly causes follow-up costs due to repairs or breakdowns.

When purchasing branch pieces, there is much more to consider than just the price or nominal diameter. The right geometry, suitable materials, connection technology, pressure and temperature resistance, conformity to standards and fluidic design are crucial. This is the only way to ensure that systems function safely, efficiently and with low maintenance for many years.
