DN32-DN2000 Single Sphere Power Plant Expansion Joints NBR EPDM Rubber PN40

DINKONDA GLOBAL Power Plants Special DN32-DN2000 Single Sphere, Double Sphere High-pressure Pipeline Flexible Compensator PN40 Flexible NBR/EPDM Rubber Expansion Joint

Product Overview
PN40 flexible rubber joint, also known as rubber expansion joint or rubber flexible connection, is a high-pressure pipeline flexible compensation accessory. The product is made of high-quality rubber material and is integrally formed. It is equipped with various specifications of metal flange structures such as national, American, and German standards, and has excellent pressure resistance, vibration reduction, noise reduction, displacement compensation, and sealing and anti-seepage performance. It can effectively solve the stress problems caused by pipeline thermal expansion and contraction, equipment vibration, and installation deviation, buffer the impact of pipeline operation, protect supporting equipment such as pipelines, pump bodies, valves, etc. It is an indispensable pipeline supporting component in water supply and drainage, fire protection, shipbuilding, and oil and gas engineering systems.

Technical Specifications
1. Nominal pressure: PN40 (high-pressure customized version, suitable for high-pressure pipeline conditions)

2. Specification and size: DN32-DN2000, full size can be customized to meet the installation requirements of pipes with different diameters

3. Compatible with international flange standards such as ANSI (American Standard), BS (British Standard), JIS (Japanese Standard), DIN (German Standard), EN (European Standard), etc., suitable for various pipeline engineering projects at home and abroad

4. Product structure types: divided into single sphere and double sphere structures, which can be selected according to the pipeline compensation amount and vibration intensity. Double sphere structures have larger compensation displacement and better vibration reduction effect

5. Main rubber material
NBR nitrile rubber: excellent oil resistance, suitable for oil and gas, oil medium pipelines, wear-resistant, anti-aging, and strong sealing;
EPDM (Ethylene Propylene Diene Monomer) rubber: resistant to high and low temperatures, acid and alkali, and aging, suitable for drainage, firefighting, and general fluid conditions, with a longer service life.

6. Connection methods: flange connection and threaded connection, suitable for different installation scenarios and pipe diameter specifications

7. Flange material: optional carbon steel galvanized flange and stainless steel flange. Carbon steel galvanized flange is rust resistant, wear-resistant, and cost-effective; Stainless steel flanges are corrosion-resistant, suitable for humid, outdoor, and harsh chemical working conditions.

Product Advantages
1. High voltage adaptation, stable performance
This product is a PN40 high-pressure grade rubber joint, which has stronger pressure bearing capacity and higher structural strength compared to ordinary low-pressure soft joints. It can operate stably in high-pressure fluid pipelines for a long time without bulging, cracking, or leakage, and is suitable for industrial high-pressure working conditions.

2. Multidimensional compensation, strong adaptability
It can effectively absorb axial, lateral, and angular thermal displacement of pipelines, compensate for deviations caused by pipeline installation misalignment and foundation settlement, release pipeline operating stress, and avoid pipeline deformation, cracking, and damage.

3. Vibration and noise reduction, equipment protection
Rubber flexible body can block the vibration transmission generated by pump body and unit operation, weaken pipeline resonance noise, reduce equipment operation loss, and greatly extend the service life of pipelines and supporting equipment.

4. Sealed tightly to prevent leakage
Rubber and flange are precisely bonded together, seamlessly integrated, suitable for fluid transportation conditions, with excellent sealing performance, which can effectively prevent medium leakage and ensure stable operation of the pipeline system.

5. Material selection, wide adaptability to working conditions
NBR and EPDM dual materials are available, tailored to different working conditions such as oil resistance, water resistance, and high and low temperature resistance, balancing practicality and durability.

6. International universal, easy to install
Compatible with international flange standards from multiple countries, it can adapt to import and export, foreign trade engineering, and general pipelines both domestically and internationally. Installation, disassembly, and maintenance are simple and convenient, without the need for complex processes.
