Manual Tong Manual Tong Product Details: Type Other Model Number CDRT Application Oil MT SERIES MANUAL TONG are offered in torque ranges from the lightweight small 16, 000 lb-ft "SLF" to the larger and more rugged 100, 000 lb- ft "SDD" and are completely interchangeable with other major manufacturer's tongs (Varco BJ, Woolley, National Oilwell). Each tong features tough, heavy- duty designs with heat-treated hinge pins and long-lasting "stagger tooth" tong dies (Blue Diamond, Pyramid). The blue diamond die offers superior performance by providing better utilization of its unique griping surface. The tech are crowned at the middle of the die, rather than being the same height along its full length. This crowned profile reduces end loading and assures a quick, positive (but gentle) grip under all torque loads. The results are greater efficiency and longer wear, with less marking and scarring of pipe. As a bonus feature, all dies are heat-treated with a special BJ process that assures uniform tooth hardness long life. Look for the unique diamond tooth pattern and distinctive blue finish. "RED TOP" tong dies: For those who prefer a standard-type die, BJ offers Red Top dies in a full range of types and sizes for use in manual drill pipe and casing tongs. Red Top dies are manufactured in three tired and proven tooth styles, as shown on this page: Pyramid, Plain and Coarse.MT55-B MT25-C MT65-DB Model Jaw Size (inch) Torque rating (lb-ft) MT75-SDD 12~15 75,000 MT60-SDD 16 ~ 17 60,000 MT65-DB-HT65 3 1/2 ~ 11 1/4 65,000 MT4O-DB 11 3/4 ~ 17 40,000 MT55-B-HT55 3 3/8 ~ 9 55,000 MT40-B 9 ~ -11 3/4 40,000 MT25-B 13 3/8 ~ 30 25,000 MT25-C 2 3/4 ~ 10 3/4 25,000 MT16-SLF 2 3/8 ~ 8 5/8 16,000 Tongs Die Type P/N Size Weigh per doz in mm lb kg BJ Tongs Blue diamond 16402-6 1/2 x 1 1/4 x 5 7/8 12.7 x 31.75 x 149.22 9 4.08 BJ DB made in 1965 and later Pyramid 16402-2 1/2 x 1 1/4 x 5 7/8 12.7 x 31.75 x 149.22 9 4.08 BJ SDD, C, F and LF Blue Diamond 16401-6 1/2 x 1 1/4 x 5 12.7 x 31.75 x 127 6.75 3.06 Short dies for BJ Type B tong with 1 1/4" slot Pyramid 24768 1/2 x 1 1/4 x 3 7/8 12.7 x 31.75 x 98.42 6 2.72
