Product Description

Product Description

Introduction:

Stainless steel 45 90-degree elbows come in a variety of specifications, covering different sizes, curvatures, wall thicknesses, and material options. They can meet the design requirements of various piping systems. Their flexibility and reliability ensure the rapid operation and long-term stability of the systems, and they are widely used in both industrial and civil fields.

Installation Method::

The flanged limit expansion joint is suitable for flange connections on both ends. During installation:
1.Adjust the connection length between the product and the flanges.
2.Tighten the gland bolts evenly and diagonally to ensure uniform pressure.
3.Set the limit nuts to lock the expansion range, allowing the pipeline to freely expand/contract within the specified displacement while maintaining operational safety.

This joint is ideal for pipeline systems requiring flange connections on both ends, facilitating adjustment during installation or maintenance. It transmits axial thrust forces across the pipeline, reducing pressure thrust (blind flange force) and compensating for installation misalignment. However, it cannot absorb axial displacement. Commonly used for pumps, valves, and other pipeline accessories.


Product Features:

1.Easy Installation - Simplifies valve setup and withstands axial pipeline tension.
2.Robust Construction - Made from metal casting/welding, with a trapezoidal rubber sealing ring at the loose sleeve section. Under bolt pressure, the rubber compresses to form a static seal against the joint body and extension pipe.
3.Material Precision - Metals and seals are selected based on performance requirements. Externally coated with high-strength anti-corrosion paint, while bolts are high-strength carbon steel or stainless steel.
4.Flexible Displacement - A controlled gap between the body and extension pipe allows axial and radial movement, effectively absorbing pipeline thrust and easing pump/valve maintenance.
5.Pipeline Protection - Compensates for thermal expansion, reduces blind flange force, and safeguards connected equipment (e.g., pumps, valves).
