Flow control solutions for every industry
ESG supplies expansion joints in Egypt in PN10, PN16 and PN25 — metallic joints and rubber joints, in single bellow and double bellow configurations.
01 · Metallic and Rubber Compared
Construction: Formed metal bellows with flanged or welded ends
Typically specified for: Thermal movement in hot service and high-temperature lines
Construction: Elastomer bellows with flanged ends and, where required, control rods
Typically specified for: Vibration and noise isolation at pumps and rotating equipment
Expansion Joints
02 · Single and Double Bellow
A single bellow absorbs movement across one convolution set. A double bellow provides greater movement capacity in the same line, and is specified where axial, lateral or angular movement exceeds what a single bellow can accommodate.
03 · What Expansion Joints Protect
An expansion joint is installed to absorb movement so the pipework, pumps, valves and anchors do not have to. Thermal growth in a hot line, vibration from a running pump and small installation misalignments all transfer load into flanges and equipment nozzles; the joint takes that movement instead.
04 · Where Expansion Joints Are Installed
Pump suction and discharge connections
HVAC chiller and plant room pipework
Power plant cooling water lines
Water and wastewater treatment plants
Industrial and process pipework
Marine installations
05 · Specifying an Expansion Joint
PN10, PN16 or PN25.
Metallic for thermal movement, rubber for vibration.
Single bellow or double bellow.
Axial, lateral and angular.
06 · Frequently asked questions
The questions consultants, contractors and plant engineers ask most often.
PN10, PN16 and PN25.
Metallic bellows are generally used where thermal movement and higher temperatures are involved; rubber joints are used to isolate vibration at pumps and rotating equipment.
When the movement to be absorbed exceeds the capacity of a single bellow.
