SMLSCO Quality Control System
Instrument pipelines are safety critical components, and we adopt a zero tolerance attitude towards their quality control. In addition to standard raw material and process inspections, we conduct strict dimensional tolerances, surface smoothness, and hardness tests on each batch of finished products. In addition, all pipes must undergo strict eddy current testing or hydrostatic testing to ensure their pressure bearing capacity and absence of any surface or internal defects. SMLSCO instrument tube control details ensure excellent performance under the most stringent working conditions.
Core Advantages of SMLSCO
We deeply understand your need for fast delivery and reliable supply of instrument pipelines. SMLSCO has a large inventory of 316L seamless instrument tubes in standard sizes (such as 1/4 ", 3/8", 1/2 ") all year round, which can quickly respond to your project or MRO (maintenance, repair, and operation) emergency orders and significantly shorten the procurement cycle. We not only provide high-quality products that comply with ISO and PED certifications, but also rely on 19 years of industry experience to provide you with cost-effective and fast delivery, trustworthy procurement solutions.
316L vs. 304L Material Comparison
316L and 304L are the most common options when selecting instrument pipeline materials. The core difference is that 316L contains molybdenum (Mo) element, which makes it far superior to 304L in terms of corrosion resistance, especially in resisting pitting and crevice corrosion caused by chlorides. Therefore, in marine environments, chemical treatments, or any working conditions with corrosive media, 316L is the first choice to ensure long-term safe and reliable operation of the system. 304L is suitable for general working conditions with low corrosion risk and is a more cost-effective choice.
316L Tube Application in Instrument Tubing Systems
Instrument tube is the "blood vessel" of modern industrial automation control systems, used to connect various precision instruments such as pressure gauges, transmitters, valves, etc., and transmit fluid or gas signals. Its application requires that the pipe must be able to withstand high pressure, withstand vibration, have precise dimensions, and be absolutely leak free. SMLSCO's seamless instrument tubes, with their excellent reliability and consistency, are widely used in fields such as oil and gas, chemical, power generation, semiconductors, and laboratories, providing solid guarantees for precise measurement and safe operation of critical process control systems.
The Importance of Hardness Control
The connection and sealing of instrument pipelines heavily rely on compression fittings. To achieve reliable sealing, the hardness of the pipe must be lower than that of the sleeve to ensure that the cutting edge of the sleeve can "bite" into the outer wall of the pipe, forming an effective mechanical locking and sealing line. If the pipe is too hard, the sleeve will not be able to deform effectively, which can easily lead to connection failure and high-pressure leakage. We strictly control the hardness of the pipe material below HRB 80 to ensure perfect compatibility and connection safety with major brand card sleeve joints.
Professional Packaging Methods for 316 Instrument Tube
To ensure that the surface of the precision polishing tube remains intact during transportation, we use multiple protective packaging. Each tube is independently wrapped with bubble wrap, and the ends are sealed with protective caps to prevent collisions and impurities from entering. Then neatly code the tubes and place them in sturdy plywood wooden boxes or pallets, and securely tie them together. This meticulous packaging method not only provides excellent physical protection for the product, but also reflects our high responsibility for product quality and customer experience.
