Transition elbow 90° PRESS GAS - internally threaded - 28mm-Rp1" IVAR.IVN30 GAS

Product detailed description

Gas distribution systems in industrial and commercial buildings often require precise fittings to ensure leak-free connections and long-term reliability. This 90° press elbow with internal thread is commonly used in gas pipelines for natural gas, biogas, and liquid propane. It is suitable for both new installations and system upgrades in industrial, commercial and residential applications. The elbow is installed between press-fitted pipe sections and threaded components, ensuring a secure and durable connection.

The fitting is part of a press-fit system that relies on mechanical crimping rather than welding or threading, reducing installation time and complexity. The internal thread allows for the connection of threaded valves, meters or other threaded components. The elbow must be installed according to the manufacturer’s instructions to maintain system integrity and compliance with safety standards.

Technical parameters

Material	Stainless steel 1.4404 (AISI 316L), sealing O-ring HNBR yellow
Operating temperature	-20 °C
Nominal pressure	PN 5
Code	IVNGAS30.2810
Brand	IVAR

The operating temperature range of -20 °C to +70 °C ensures the fitting is suitable for most indoor and semi-protected outdoor environments. The PN 5 pressure rating means it can handle low-pressure gas systems up to 5 bar. These parameters are essential for correct system sizing and component selection, particularly when designing networks for natural gas and biogas applications.

Installation and connection

The elbow is installed using a standard press tool compatible with the IVAR press system. The internal thread (Rp1) is designed for direct connection to threaded components such as valves or regulators. Prior to installation, the press joint must be inspected for cleanliness and damage. The press tool must be correctly aligned to avoid misalignment and uneven compression. Common installation errors include using incorrect press tools, failing to clean the sealing surface or over-pressing the joint, which can damage the O-ring.

Compatibility and accessories

This elbow is compatible with IVAR stainless steel press pipes and fittings of the same nominal size. For complete system integration, additional components such as straight press tubes, couplings and threaded adapters may be required. Installers should ensure all components are from the same press system to guarantee compatibility and sealing performance.

Technical background for designers

The elbow operates as a directional change in the pipeline, relying on the mechanical strength of the press joint and the sealing properties of the HNBR O-ring. The stainless steel material offers corrosion resistance and durability in gas environments. The internal thread provides a secure mechanical connection to threaded components. System designers should consider the thermal expansion characteristics of the stainless steel and the flexibility of the press joints to accommodate minor misalignments during installation.

Service and operation

During operation, the elbow requires no regular maintenance due to its sealed press joint design. However, periodic visual inspections are recommended to detect signs of mechanical stress or corrosion. The integrity of the press joint should be verified if the system experiences unusual pressure fluctuations or vibration. No scheduled service intervals are specified for this component.

Frequently asked questions

Can this elbow be used in biogas systems?
Yes, the elbow is suitable for biogas systems as it meets the requirements for gas media and is compatible with low-pressure applications.

Is it possible to connect this elbow directly to a threaded valve?
Yes, the internal Rp1 thread allows for direct connection to a valve or other threaded component without additional adapters.

What is the maximum allowable operating temperature?
The elbow is rated for continuous operation up to +70 °C and can withstand short-term exposure to lower temperatures down to -20 °C.

Can this fitting be used in outdoor installations?
It is suitable for use in protected outdoor environments, provided the system is designed to prevent condensation and exposure to extreme weather conditions.
