Chemical Processing - Abrasives Style 9394 ABRA-LINE™ Expansion Joint

ABRA-LINE Style 4394


Chemical Processing - Abrasive application


Chemical Processing Plant


This chemical processing plant produces acetylene. The acetylene production process involves calcium carbide that is fed through a screw feed to metering bins. Style 9394 ABRA-LINE™ Expansion joints, along with stainless steel flow liners, are installed at the bottom of the metering bins. During the manufacturing process after passing through the metering bins, calcium carbide is mixed with water, causing a chemical reaction, which produces the acetylene.


  1. Size: 10” x 6” 9394 ABRA-LINE™ Expansion Joints with stainless steel flow liner
  2. Temperature: Ambient
  3. Application: Screw feed metering bin
  4. Media: calcium carbide
  5. Pressure: up to 15 PSI


There are now 12 ABRA-LINE™ expansion joints installed in the plant which have outlasted the previous solution which would only last 6 months in this application. The customer is hoping to get years of service out of them due to the abrasion resistance of ABRA-LINE™ and the use of a flow liner.

Garlock Expansion Joints offer superior performance, reliability and service life. This results in an improvement in plant safety, an increase in the mechanical integrity of equipment and allows customers to gain a competitive advantage in the market place.
