Trusted Alloys for Demanding Oil & Gas Applications

Oil and gas equipment operates where heat, pressure, vibration and abrasion are constant. Lucas Milhaupt helps operators, OEMs and repair shops build stronger, longer-lasting assemblies with engineered brazing alloys, fluxes and pastes that hold up in harsh environments. From tool joints and wear parts to valves and heat exchangers, our solutions support both new build and MRO needs. With global manufacturing and distribution, we deliver consistent quality and reliable supply wherever your projects are.

 

 

Why customers choose Lucas Milhaupt

  • Performance in harsh service: Our brazing solutions are formulated for shock, vibration, thermal cycling and corrosive media so critical joints stay sealed and secure longer, reducing unplanned downtime.
  • Portfolio built for carbide, steel and copper: Highlighted solutions include Silvacut® and Silvaloy® silver-braze alloys for bonding tungsten carbide to alloy steels, plus Sil-Fos® for copper-to-copper and copper-to-brass assemblies and Handy Flux™/Handy Paste™ options for clean, repeatable results.
  • Application and process support: We help you select the right filler metal and flux, optimize joint design, and tailor paste viscosity or pellet forms to your production method, whether you braze in a torch, furnace, or induction process.
  • Global reach and dependable supply: Multiple production sites and a worldwide distribution network mean consistent availability, shorter lead times and the scale to support large capital projects and fast-turn repairs.

 

 

Applications we support

  • Downhole drilling bits and reamers: Brazing of tungsten carbide inserts and wear protection features for PDC and roller-cone designs to withstand impact, abrasion and high temperatures.
  • Drilling and completion wear components: Stabilizers, subs, mandrels and bearing surfaces that require robust carbide-to-steel joints for extended service life.
  • Valves, pumps and compression equipment: Seals, impellers, housings and trim where leak-tight joints and corrosion resistance are vital in sour and corrosive environments.
  • Surface facilities and instrumentation: Tube-to-header joints in heat exchangers, manifolds and precision fittings for reliable performance in processing, measurement and control systems.

Engineered Joints for Extreme Service

Rock, shale, and hard-metal ores destroy ordinary joints in minutes. The cutters, picks, and drill bits that tame these materials rely on brazed joints that survive crushing loads, high-speed abrasion, thermal shock, and corrosive drilling fluids. Lucas Milhaupt engineers and manufactures the high-purity alloys, custom preforms, and application expertise that keep cutting structures sharp and secure where failure isn't an option.

Application Engineering that Shortens Cycle Time

Collaborative joint design, preform sizing (SilvaCut), and process tuning to improve wetting, control filler volume, reduce rework, and boost throughput. Our team can help with root-cause failure analysis, feed-speed recommendations and offer cost-down alloy substitutions. 

Reliable Global Supply with Tight Control

Keep critical assemblies moving with a supply chain built for high-consequence work. Lucas Milhaupt has global manufacturing sites and disciplined inventory programs to deliver the right alloy, in the right form, when you need it.
