Oil and Gas Drilling Components Corrosion Protected

Manufacturer's of oil and gas drilling components asked for an in-house metal finishing process to provide robust corrosion protection, break-in lubricity and galling resistance. Birchwood Technologies provided the TRU TEMP low temp black oxide process.

The TRU TEMP process operates at 200 degrees and forms a satin black magnetite finish that protects critical surfaces in storage, shipment and startup, resists galling and aids in break-in, all without a dimensional change. The process takes just 30 minutes.

The TRU TEMP finish is Mil Spec and RoHS compliant, and withstands up to 100-150 hours of neutral salt spray or several hundred hours of humidity, verified by independent testing. The finish is 0.5 microns thick (20 millionths) and has no effect on material hardness or load-bearing properties. Its crystalline structure allows it to effectively hold a rust inhibitor and serves as a sacrificial barrier to provide break-in lubricity and galling resistance. Critical parts are protected in storage or overseas shipment.

The TRU TEMP low temperature black oxide process can be installed in any plant setting, without endangering personnel or surrounding equipment. The operating solutions contain no EPA regulated chemicals; process rinse waters are normally sent to the sewer as non-hazardous discharge. Most process lines do not require waste treatment equipment.

In areas with restricted water/sewer availability, the TRU TEMP process can be configured to utilize the NEAR-ZERO Water Recycler to reduce process water consumption by 90+ percent. This benefit simplifies installation and allows the line to operate with very low water usage. TRU TEMP process lines are available in any size to fit part size and production volume.
