T-piece 90° PRESS GAS - internally threaded - 18-Rp1/2"-18 IVAR.IVN42 GAS

Product detailed description

The 90° T-piece is a critical component in gas distribution systems, particularly in industrial and commercial heating applications. It is commonly used in gas pipelines for natural gas, biogas, and liquid propane. Installers working on gas supply lines for heating systems, industrial burners, or gas storage facilities will find this fitting essential for creating branch connections in press systems. The fitting ensures a secure and leak-free connection in environments where gas flow must be reliably maintained and controlled.

Typical installations include gas supply lines in industrial buildings, commercial kitchens, and gas-fired heating systems. The T-piece is often integrated into press systems where it connects to other press fittings and internally threaded components. It is suitable for use in both new installations and system expansions where a branch connection is required without the need for welding or additional sealing materials.

Technical parameters

Material	Stainless steel Wst. Nr. 1.4404 (AISI 316L), sealing O-ring HNBR yellow
Operating temperature	-20 °C
Nominal pressure	PN 5
Code	IVNGAS42.181218
Brand	IVAR

The operating temperature range of -20 °C to +70 °C makes this fitting suitable for use in both cold and warm environments. The nominal pressure rating of PN 5 ensures compatibility with standard gas distribution systems. These parameters are essential for selecting the correct fitting for the intended application and ensuring long-term reliability under normal operating conditions.

Installation and connection

The T-piece is installed using a press connection on one side and an internal thread on the other. The press connection requires a compatible press tool to compress the fitting onto the pipe. The internal thread side accepts a standard Rp1/2" connection. Before installation, ensure that the pipe ends are clean and free of burrs. Verify that the press tool is correctly set for the pipe size and material. Common installation mistakes include using the wrong press tool, failing to clean the pipe ends, or over-tightening the internal thread connection. Always follow the manufacturer's installation guidelines to ensure a secure and leak-free connection.

Compatibility and accessories

This T-piece is compatible with other press fittings and internally threaded components in gas distribution systems. It is designed for use with stainless steel pipes of the same material grade. No additional accessories are required for installation, but it is important to ensure that all components in the system are compatible with the same pressure and temperature ratings. Related products include press fittings and internally threaded adapters for gas systems.

Technical background for designers

The T-piece operates by allowing a branch connection in a gas pipeline. The stainless steel construction provides resistance to corrosion and ensures long-term durability. The HNBR sealing ring provides a reliable seal against gas leakage. The internal thread allows for easy connection to other threaded components. The integration of the T-piece into the system should consider the overall pressure and temperature conditions to ensure optimal performance. The material properties of stainless steel 1.4404 and the HNBR sealing ring contribute to the fitting's ability to maintain a secure connection over time.

Service and operation

Regular inspection of the T-piece is recommended to ensure that the connection remains secure and leak-free. Check for signs of wear or damage to the sealing ring and the internal thread. If any issues are detected, the fitting should be replaced immediately. No specific service intervals are provided in the brief, but it is advisable to follow the manufacturer's maintenance guidelines for the system as a whole.

Frequently asked questions

Can this T-piece be used with biogas systems?
Yes, the T-piece is suitable for use with biogas systems as it is designed for gas distribution networks including biogas.

Is the T-piece compatible with press tools from other manufacturers?
