Produkt-Beschreibung

ANSI Standard Flange Rubber Expansion Joint Shock Absorber for Pipeline

The single-ball rubber joint is a highly elastic and airtight pipe connection component. It consists of a rubber ball with an inner rubber layer, a reinforcement layer, and an outer rubber layer, and a loose metal flange.

It is widely used in various piping systems, effectively absorbing vibration and noise, compensating for thermal expansion and contraction caused by temperature changes, and allowing a certain degree of deflection.

Rubber Material Selection Guide

Natural Rubber (NR): Suitable for ordinary water and air media, temperature range -20°C to +80°C

Ethylene Propylene Diene Monomer (EPDM): High-temperature and ozone-resistant, suitable for hot water and steam media

Nitrile Butadiene Rubber (NBR): Excellent oil resistance, suitable for oil-based media

Chloroprene Rubber (CR): Excellent weather resistance, suitable for outdoor environments

Application Scenario Details

Chemical Piping Systems
In acid and alkaline media transport pipelines, a Teflon-coated lining design, combined with corrosion-resistant rubber, effectively resists chemical corrosion. After use at a Guangxi chemical company, pipeline leakage rates were reduced by 95%.

HVAC Systems
EPDM connectors, designed specifically for high-temperature hot water, have operated continuously in an 85°C circulating hot water system for three years without signs of aging. The vibration-damping effect reduces pump noise by 15 decibels.

Water Supply and Drainage Engineering
Large-diameter DN1200 connectors are used in urban water supply systems, successfully compensating for 25mm displacement caused by foundation settlement and preventing pipe ruptures.

Professional Installation Steps
Pre-installation Inspection: Confirm that the flange sealing surface is flat and undamaged, and that the bolt holes are aligned.

Precise Positioning: Use a dedicated positioning tool to ensure concentricity between the joint and the pipe.

Stepped Tightening: Tighten the bolts in three steps using a crisscross pattern.

Pressure Test: First, perform a static pressure test at 1.5 times the working pressure, maintaining pressure for 30 minutes.

Maintenance Recommendations
Monthly check for surface degradation

Quarterly check bolt tightness

Perform a comprehensive inspection annually

Create a maintenance log to record equipment usage

Testing Standards
All products undergo the following before shipment:

Airtightness test: 1.5 times the working pressure for 10 minutes

Vacuum test: -0.09 MPa for 5 minutes

Displacement performance test: Fatigue test simulating actual working conditions

Material analysis: Spectroscopic analysis of rubber components to ensure compliance with standards

Solutions to Common Problems
Problem 1: Leakage after installation
Solution: Check the flange sealing surface for flatness and re-tighten the bolts in a crisscross pattern.

Problem 2: Cracks develop during use
Solution: Verify the medium temperature exceeds the rubber tolerance and replace the connector with a high-temperature-resistant material.

Problem 3: Pull-out prevention device inoperative
Solution: Check the stop bolts for looseness and readjust the stop distance.
