CSR.UK – axial bellows expansion joints with a reinforced welded casing with a nominal pressure of PN 25 Bar (25 kgf / cm2) as standard.

     Axial bellows expansion joints with a reinforced protective casing are used to compensate for axial movements arising from the thermal expansion of the heating network pipeline inside premises, during above-ground laying, in chambers, through or non-through channels, tunnels. The reinforced casing of the expansion joint serves as a guide, reliably protects the bellows from excessive stretching and bending moments. 

     At the request of the Customer, an observation window can be included in the design for the possibility of monitoring the condition of the bellows surface during the entire period of operation. It is allowed to apply thermal insulation on the casing of the compensator after their installation in the heat pipe simultaneously with the thermal insulation of the heat pipe.

       This type of expansion joints is recommended for replacing stuffing box expansion joints when installed in existing heat chambers.

Цель применения:

• Compensation of axial movements resulting from temperature changes in the length of pipelines;
• Removing vibration loads, sealing pipelines;
• Prevention of destruction and deformation of pipelines.

Operating conditions:

Working medium: steam, water.

Design Features

• Compensator version: reinforced protective casing, can be fitted with an internal screen.
• Connection type: butt weld, flanged.
• Number of sections: one-piece (one bellows) or two-piece (two bellows).
• Number of bellows layers: multi-layer.
