Precision Polishing and Bright Annealed Process
SMLSCO seamless tubes undergo precision multi pass inner and outer
wall polishing treatment to ensure high surface smoothness, no
scratches, effectively reducing fluid resistance and preventing
scaling, which is crucial for heat exchange efficiency.
Subsequently, a bright annealing process was employed to perform
heat treatment under controlled atmosphere, eliminating cold
working stress and restoring the excellent mechanical properties of
the material. This process can form a bright oxide free surface,
ensuring the highest cleanliness and corrosion resistance of the
pipe, providing reliable guarantee for high-end applications.
SMLSCO Polished Tube Application in Heat Exchangers
SMLSCO precision seamless tube is a core component designed
specifically for various heat exchanger and condenser systems such
as shell and tube, coil, etc. Its stable heat exchange performance,
excellent high pressure resistance, and high reliability under
thermal cycling ensure efficient energy transfer. Smooth inner and
outer surfaces can minimize fluid adhesion and scaling, extending
equipment maintenance cycles. The product is widely used in the
fields of petrochemicals, energy and power, food processing, and
HVAC, providing solid support for the stable operation of key
systems.
SMLSCO Quality Control System for 316L Polished Tube
SMLSCO implements a rigorous three-level quality inspection system
to ensure that every pipe delivered meets the highest standards.
Starting from high-quality raw materials from certified suppliers,
through online monitoring of dimensions and surfaces during the
production process, and conducting 100% comprehensive testing of
finished products before shipment. All testing data and product
photos will be archived for complete traceability. We also support
customers to designate third-party organizations such as SGS and T
Ü V for inspection, providing completely transparent and reliable
quality assurance.
Core Advantages of SMLSCO
We have become your reliable partner with three core advantages.
- We have a standing inventory of over 2000 tons, ensuring that
seamless pipes of regular size can be delivered quickly within 2
weeks, effectively shortening your project cycle.
- Based on 18 years of industry experience and a bulk procurement
model, our products are highly competitive in price while ensuring
high quality.
- The product complies with strict international standards and has
passed authoritative certifications such as ISO and PED, providing
you with stable and reliable pipeline system solutions.
Material Properties of 316/316L
316/316L stainless steel exhibits excellent corrosion resistance
due to the addition of molybdenum, especially in environments
containing chlorides, effectively resisting pitting and crevice
corrosion. Its excellent high-temperature strength and creep
resistance make it an ideal choice for high-temperature and
high-pressure working conditions. As a low-carbon version, 316L can
maintain excellent intergranular corrosion resistance without
annealing after welding, ensuring the long-term stability and
safety of the equipment in the welding area, fully meeting the
requirements of harsh industrial environments.
Professional Packaging Methods for 316 Polished 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.
