Rubber lined pipe

Rubber lined pipe is used to transport Abrasive Slurry solutions, Corrosive Chemicals, and many other liquids from one place to another.

Steps for Creating a Rubber Lined Pipe

Our plant carefully considers temperature, chemical composition and concentration of the materials being conveyed to determine the best compound for your rubber pipe.

  • Fabricate the pipe
  • Inspect the Weldment
  • Prepare the Substrate (Blasting)
  • Apply Adhesive System
  • Make a Rubber Tube
  • Stitch the Tube Seam
  • Insert the Tube into the Pipe
  • Apply the Flange Faces
  • Vulcanize (Cure) the Lining
  • Inspect & Spark Test the Lining
  • Blast Unlined Surfaces
  • Paint the Unlined Surfaces
  • Final Inspection

With the proper rubber pipe lining, a pipe can withstand years of abrasive and corrosive service conditions. Rubber compounds are engineered for chemical resistance to protect your pipe from the effects of acids and oxidizing agents.

Rubber Lining Options

For fluid streams with a high solids content or aggressive chemical make-up, rubber lined steel pipe has traditionally been a very effective solution. There are a variety of rubber compounds and durometers available. While other compounds may be available, noted below are common solutions for mining applications.

Rubber Lining Attributes:

Pipe size is never a concern when working with Industrial Rubber. An innovative application process makes it possible to rubber line pipe ranging from 3 inches in diameter up to the largest diameter manufactured.

Soft Natural Rubber

  • Lowest Cost
  • Excellent abrasion
  • tear resistance
  • Good general chemical resistance
  • Stable in cold weather or rapid temperature changes
  • 40-60 durometer typical
  • Pure Gum Based

Hard Natural Rubber

  • Moderate cost
  • Excellent chemical
  • permeation resistance
  • Heat resistant over 200˚F
  • Physically tough
  • 60-90 durometer typical
  • Ebonite based

Chloroprene/Butyl/Hypalon Rubber

  • More expensive
  • Good to excellent chemical
  • ppermeation resistance
  • Heat resistant over 200˚F
  • Stable in cold weather
  • rapid temperature changes
  • Oil Resistant (Hypalon)
  • 40-60 durometer typical

Since most Rubber Lined Pipe applications are for transporting abrasive slurries, we test our materials for abrasion resistance to ensure we are providing you with the best product suited to your application.

We install rubber linings in pipe as small as 1½” dia. and as large as 144″ dia. We vulcanize (cure) the lining installed in pipe up to 88″ diameter (flanged) in our autoclaves. Curing in an autoclave produces superior adhesion properties over other processes (i.e. atmospheric and internal steam). Autoclave curing also maximizes the lining life in the pipe versus other methods.

We can fabricate and rubber line your pipe with a minimum lead-time. All Rubber Lined Pipe orders receive the same attention, whether it’s a large order, or a single piece.

Weled steel pipe specification, Standard and identification

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding.
