Quality Assurance

Instrument pipelines are safety-critical components, and we maintain a zero-tolerance approach to quality control. Our comprehensive testing includes:

  • Raw material and process inspections
  • Dimensional tolerance verification
  • Surface smoothness evaluation
  • Hardness testing
  • Eddy current or hydrostatic testing for pressure capacity
Supply Chain Advantages

SMLSCO maintains large inventories of 316L seamless instrument tubes in standard sizes (1/4", 3/8", 1/2") to ensure rapid response to project or MRO emergency orders. Our 19 years of industry experience enables us to provide:

  • ISO and PED certified products
  • Cost-effective procurement solutions
  • Fast delivery times

Instrument Tubing Applications

Seamless instrument tubes serve as critical components in industrial automation systems, connecting precision instruments like pressure gauges, transmitters, and valves. Our tubes are engineered for:

  • High-pressure resistance
  • Vibration tolerance
  • Precise dimensional accuracy
  • Leak-free performance

Common applications include oil & gas, chemical processing, power generation, semiconductor manufacturing, and laboratory systems.

Hardness Control for Secure Connections

We maintain strict hardness control (below HRB 80) to ensure:

  • Proper compression fitting engagement
  • Effective mechanical locking
  • Reliable sealing performance
  • Compatibility with major brand fittings
Protective Packaging

Each tube receives comprehensive protection:

  • Individual bubble wrap
  • Protective end caps
  • Sturdy plywood cases or pallets
  • Secure bundling for transport

Our packaging methods ensure surface integrity and prevent contamination during shipping.
