Cr Iron Pump Spool Liner Inserts Solve High Wear Problem

sam — Sat, 17 Oct 2009 06:38:33 +0000

An oil sands customer had a problem with extreme high wear on pump spools in the hydrotransport line for oil sands.

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.

Cyclofeeder Wear Liner

An oil sand customer from Ft McMurray had a Cyclofeeder liner that required new wear liners. 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.

Frac Pump Sand Slinger

One of our oil service companies used our Pliant 25 alloy to improve the wear life of their sand slingers. The slingers are a critical high wear component in hydraulic fracturing pumps. They’re used to mix sand in the frac pumps. The slingers are over 600 Brinnell hardness and balaced to a GI balance spec.

The chrome iron slingers used in the frac units achieved double the service life at half the price of the original product.

CADI feed chute liners

CADI feed chute liners on a usage trial at a large Canadian copper mine.

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.

Austempered Ductile Iron (ADI) gear segments

Austempered Ductile Iron (ADI) gear segments used in the mining industry.

These gear segments are used in rail tipping 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.

Balanced Machined Impellers

Balanced Machined Impellers at >600BHN in ASTM A532 CLIII Type A.

A large OEM customer was closing their foundry and machine shop and was looking for a supplier to provide turn-key product. These are machined, heat treated, painted and balanced impellers in ASTM A532 CLIII A chrome white iron.

Trunnion Liner

a 5800 pound ASTM A532 CLIII Type A >650BHN fully machined casting made for a mine here in British Columbia.

The mining customer had a shutdown situation and Penticton Foundry provided the replacement trunnion liner in record time. No one in western Canada or U.S. was able to quote the part except Penticton Foundry
