Overview

As a century old brand in the field of industrial fluid connection and compensation, ELAFLEX has launched the SERV-G series yellow ring rubber expansion joint with German precision as its core foundation. Focusing on harsh transportation scenarios such as petroleum based products, various fuels, urban gas, and natural gas, ELAFLEX has become the core solution for flexible compensation of pipeline systems with full specification model coverage and multi working condition adaptability. $r $n Germany Elaflex RV-GR rubber expansion joint flexible connection

Product Details

In the transportation of highly corrosive fluids in chemical, environmental, municipal and other fields, pipeline systems have long faced multiple challenges such as acid-base erosion, thermal expansion and contraction, equipment vibration and installation deviation. Elaflex from Germany, with nearly a century of accumulated fluid connection technology, has launchedSERV-GR GreenBand series rubber expansion jointWith professional corrosion-resistant materials, three-dimensional compensation capability, and reliable sealing performance, it has become an ideal flexible connecting component for corrosive medium pipelines, providing protection for the safe and stable operation of industrial pipelines.

1、 Product positioning: Customized for corrosive working conditions

Elaflex RV-GR is designed forAcidic, alkaline, corrosive chemical wastewater, oily compressed airThe specialized rubber expansion joint designed for harsh working conditions adopts high-performance CSM (chlorosulfonated polyethylene) material, which precisely matches the strong corrosive medium transportation needs of industries such as chemical, electroplating, sewage treatment, metallurgy, etc., and solves the pain points of aging, leakage, and failure of traditional expansion joints from the root.

2、 Core advantages, forging performance

1. Corrosion resistant, suitable for strong corrosive media

adoptCSM corrosion-resistant lining formed by integrated moldingThe seamless and smooth structure has no stagnant dead angle, which can withstand various acids, alkalis, salts and corrosive chemical waste liquids for a long time. The anti-aging and anti swelling properties are far superior to ordinary rubber materials, greatly extending the service life of the pipeline.

2. Three dimensional displacement compensation to release pipeline stress

Single ball corrugated tube structure, equipped withAxial, lateral, and angular three-dimensional compensation capabilityEfficiently absorb the displacement and stress caused by pipeline thermal expansion and contraction, foundation settlement, and equipment operation, reduce pipeline fatigue damage, and avoid flange loosening and leakage.

3. Noise reduction and shock absorption to protect equipment lifespan

High quality elastic material with high efficiencyAbsorb vibrations from equipment such as pumps, compressors, fans, etcBarrier pipeline structure noise and fluid low-frequency noise, reduce vibration transmission damage to precision equipment, lower factory noise, and improve operational comfort.

4. Low reaction force, easy to install, suitable for complex working conditions

Low reaction force and low flow resistance design, without adding additional pipeline load; collocationRotating metal flangeOn site installation is flexible and convenient, effectively compensating for installation errors, shortening the construction period, and adapting to various complex pipeline layouts.

5. German Seiko, safe and reliable

Produced according to European standards, with integral molding without splicing, and excellent sealing performance;DN25-DN700 full specification coverage， PN16 standard pressure bearing, working temperature * * -20 ℃ to+90 ℃ * * (short-term up to+110 ℃), meets the temperature and pressure requirements of most industrial corrosion conditions.
