Core Application & Target User Demand
This catalog focuses on lubricating pipeline assembly parts exclusively compatible with BOMCO drawworks models, including JC-90, JC-70, JC-50, JC-40, JC-90DB, JC-70DB, JC-50DB, JC-40DB, JC-90D, JC-70D, and JC-5. Tailored for oilfield drilling maintenance teams, BOMCO authorized service providers, and drilling contractors, it addresses pain points such as pipeline blockage, leakage, and oil supply failure that cause inadequate lubrication of transmission components and lead to equipment downtime. The core value lies in ensuring efficient, stable, and continuous lubricating oil delivery to key components of BOMCO drawworks, adapting to harsh oilfield conditions (high dust, humidity, and vibration), and extending the service life of transmission systems by maintaining optimal lubrication status.
1. Copper Pipes
Copper pipes are the core conveying components of the lubricating pipeline assembly, responsible for transmitting lubricating oil from the oil tank to various lubrication points of the drawworks. They require high pressure resistance, corrosion resistance, and good ductility to adapt to the complex layout of the oilfield equipment. A field maintenance case: A BOMCO JC-90DB drawworks experienced insufficient lubrication of the input shaft bearing. Inspection found that the 10X12/G93-1 copper pipe was blocked by oil sludge accumulation, resulting in inadequate oil supply. After replacing the copper pipe and cleaning the entire lubrication circuit, the bearing lubrication was restored to normal. All copper pipes comply with GB/T 18033-2007 (Copper and Copper Alloy Capillary Tubes) and API Spec 7K Clause 6.3 (Lubrication Systems) requirements.
