The liners are High Chrome White Iron used in mining and crushing. Applications  could include apron feed liners, feed chute liners, transfer chute liner or Trojan horse liners.

Cross-section wye bi-metallic piping

A major Oil Sands facility replaced CCO (chromium carbide overlay) 28″wye and lateral piping assemblies with bi metallic piping from Penticton Foundry.

The mine found that the CCO wyes and laterals that transported bitumen in their hydrotransport piping was a very high wear component. Outages and maintenance downtime were a major cost concern.

We proposed an assembly that would have a solid high chrome white iron casting inserted into a steel pressure boundary shell.

There are a number of advantages to the design. One of the major issues was increased wear life. The minimum wall of the casting was 1.25″ but in high wear areas (crotch of the wye and lateral) we increased the casting thickness to as much as 8″.

The other advantage was rebuild, the assembly is designed to have the casting replaced once the liner has reached its maximum service life. This is a major cost saving to our customer as the pressure shell can be reused.

7000 lb Solid Chrome Elbow made by Penticton Foundry

Penticton Foundry recently shipped a 60 degree solid chrome elbow to a mine in the Alberta Oil Sands.

The elbow was specifically made to increase production from the customer’s cyclone launders. The elbow was designed to have double the wall thickness on the outside radius where the majority of wear takes place.

This customer expects at least four times the life from the cast elbow over the CCO fabrication it is replacing.

Fracking Tub

The blender tubs, liner and mixing impellers used in the fracking process are ASTM A532 CLIII A (or 3A) chrome iron castings. The cast components usually last at least 6 times longer than T1 fabricated plate overlayed with CCO. (chromium carbide overlay)

The impeller is cast, machined and balanced. Hardness is >550 BHN (55RC)

One of our customers trialed a sample ASTM A532 chrome iron cast impeller. It was finally replaced after pumping 50,000 tons (100 million pounds) of proppant. The prior steel impellers wore out after only 8,000 tons.

Fracking impeller with liner

We worked with the customer to design a reusable spool that houses a 1 ¼” thick wall 27% chrome iron liner >650 Brinnell.

Not only will the chrome iron liner wear longer than the CCO, the fabrication is reusable. Once the liners wear out, the fabrications will be shipped back to Penticton to have another liner installed and put back into service.

Prior to using our insert spool the customer used fabricated spools made from chromium carbide overlay plate (CCO). The customer found the CCO did not have the wear life required and that the cost of fabricating CCO was prohibitive.

They wanted a turnkey operation, they wanted the vessel completely lined and ready to install in their hydrotransport line for pumping oil sands.

The vessels were 16’ in diameter and had to be lined with over 80,000 pounds of castings.

The quality requirements were exceptionally stringent. The castings required ultrasonic inspection, liquid penetrant inspection, dimensional inspection, hardness, and chemistry. In addition the chrome iron castings had to meet demanding retained austenite requirements and pass the G65 wear test.

The project was a complete success and came in on budget and under the originally quoted time frame.

The chrome iron slingers used in the frac units achieved more than more than 4 times the service life at half the price of the original product.

The purpose of the trial is to determine the castings ability to wear and absorb impact.

The trials are ongoing but at this point the CADI has performed beyond our expectations.

These gear segments are used in rail dumping assemblies that empty entire rail cars of ore. The alloy use for the gears has a tensile strength of 150,000 PSI a yield strength of 100,000 PSI with 7% elongation. The gears are 100% X ray inspected.

ADI is chosen for this tough application due to the strength of the alloy and the surface hardening effect on the gears. The top .0015” of the gear tooth will harden to nearly 600BHN when subjected to impact.
