RANKIN INDUSTRIES OFFERS TRIO OF NEW MAINTENANCE AND REPAIR OPTIONS
TO FIGHT WEAR AND CORROSION
NOVEMBER 2, 2010 (RANCHO CUCAMONG, CA) – A trio of new products from Rankin
Industries® will benefit oil industry maintenance and repair operations with new weld
applications and weld removal options. Rankin’s new alloys include Complex Integrated
Microstructure - 7 (CIM-7), a nano-crystalline structure that resists virtually any abrasive
materials and is specially designed to be used on tool joints, and NON-MAG 1™, a metal cored
sub arc wire containing Nickel, Chrome, Manganese, and Silicon that’s micro structure is fully
austenitic and non-magnetic and is designed to band non-magnetic down hole tools and
equipment. Completing the new M&R package is RanCUT™, an arc cut wire designed to remove
hardfacing deposits without air assist.
“We have been working closely with our customers in the petrochemical industry to find
opportunities to improve performance of their down hole equipment and to make maintenance
operations faster while achieving better banding performance and efficient weld removal,” said
Rick Ferry, Rankin Industries CEO.
CIM-7™ is part of the newest metallurgical frontier and possesses high hardness in the first
layer. Rankin CIM-7 as deposited Rockwell C hardness for single layer band is 60 to 62. Oil
drilling applications include hardfacing drilling tools, tool joints, and drill collars. Other
industries will benefit where applications require low surface friction coupled with high
hardness.
Applications for Rankin’s NON-MAG 1™ include down hole survey equipment that is nonmagnetic such as drill collars, and directional drill heads where they house sensitive electronic
equipment to find locations or mapping.
RanCUT™ arc cut wire was developed for operators to remove old hardfacing deposits from
circumferential shaped parts including drill pipe tool joints to prepare for new welds, without
the use of compressed air. RanCUT works best on round parts in the three o’clock or nine
o’clock arc position where gravity pulls the molten puddle material off the part. RanCUT offers
very high metal removal rates and is an excellent choice for drilling tools, tool joints, and drill
collars.
The company also reintroduced Rantube ™, a premium large diameter tubular hardfacing
electrode that combats wear caused by severe abrasion, erosion, impact, and heat.
Hardfacing with high-deposition Rantube electrodes extends part service life and can be applied
to cast iron, manganese steel, and mild steel without preheat although high carbon and alloy
steels may require preheat. Rantube deposition rates are up to 6.5 pounds per hour for the
7/16" (11mm) electrode size. The 1/4" (6mm) electrode is designed for all position welding and
can be used at low amperage to hardface thin edges on tillage tools and similar parts.
Rankin Industries™ is a specialty formulator and manufacturer of high-quality hardfacing
products and metal alloys for specialized maintenance, OEM, repair industries, and commercial
and industrial applications. The company also offers expert custom alloys capabilities. The
Protective Metal Alloys™ division of Rankin Industries™ produces a range of specialty alloy and
wear-resistant products including hardfacing alloys, and a selection of specialty brazing
preforms, and build-up and overlay products. The division serves a wide range of industries,
from petrochemical and power generation to tool and die, rubber, mining and others. Rankin®
is led by a team of industry experts who share a commitment to superior quality, service, and
cost-effective welding solutions. The company is based in San Diego, California and serves
customers worldwide.
