Field Work

Rubber lining has been our primary line of business since we were founded in 1958. In addition to rubber lining pipe and tanks, Proco can rubber line almost any metal part. We are an approved applicator for Blair Rubber CompanyRubber SourcePolycorp and Weir. We maintain a technical liaison with the rubber lining manufacturers as further support for your rubber lining requirements. We will select and install the rubber lining best suited to your needs. Rubber lining work can be performed in our shop, or at your facility. We can provide our metal fabrication services for your pipe, tank, and other rubber lining needs. When your project requires it, we can apply a wide array of external paint systems or coatings. We can pick-up and/or deliver your parts.


All parts to be rubber lined must be fabricated without sharp corners.
All welds must be continuous (Fabrication Requirements in PDF format).


The part is first inspected for suitability for rubber lining and dimensional correctness.


The metal is then cleaned to SSPC-SP1 to remove oil, grease, dirt, and other contaminants.

Surface Preparation

The part is blasted to SSPC-SP5 “White Metal” surface.


The blasted metal is inspected for proper anchor pattern depth.


The adhesive system appropriate for the rubber lining system is applied.

Rubber Lining

Rubber sheets are cut to size and laid into position on the adhesive-coated surfaces.
Rubber is then rolled out to tightly bond the rubber lining sheets to the metal.

Pre-Cure Inspection

The rubber lining is visually inspected & spark tested.

Curing (Vulcanization)

The rubber lining is vulcanized per the rubber manufacturer’s specification.

Post-Cure Inspection

The lining is visually inspected & spark tested again.


The items are finished and painted to your specifications.

Final Inspection

The items are inspected for compliance with all project specifications.
All quality documents are finalized, electronically scanned and stored.
Original documents sent to customer (if requested).

Surface Preparation
The most important step in producing proper adhesion to any substrate is the first step…surface preparation. Without the proper surface preparation, any bonding attempt is very likely to fail.We can perform any kind of surface preparation for steel parts. No job is too big. We can also blast other substrates such as Aluminum, Copper, Brass, Stainless Steel and Hasteloy.

Solvent Cleaning – Removal of oil, grease, dirt, soil, salts and contaminants by cleaning with solvent, vapor, alkali, emulsion, or steam.
Rubber Lining Services 1
White Metal Blast Cleaning – Removal of all visible rust, mill scale, paint, and foreign matter by blast cleaning by wheel or nozzle (dry or wet) using sand, grit or shot. (For very corrosive atmospheres where high cost of cleaning is warranted.)
Rubber Lining Services 2
Commercial Blast Cleaning – blast cleaning until at least two-thirds of the surface area is free of all visible residues. (For conditions where thoroughly cleaned surface is required.)
Rubber Lining Services 3
Brush-Off Blast Cleaning – Blast cleaning of all except tightly adhering residues of mill scale, rust and coatings, exposing numerous evenly distributed flecks of underlying metal
Rubber Lining Services 4
Near-White Blast Cleaning – Blast cleaning nearly to White metal cleanliness, until at least 95% of the surface area is free of all visible residues. (For high humidity, chemical atmosphere, marine, or other corrosive environments.)
