🛠️ Product Description
Seamless Tube Technology: Our seamless tubes are engineered for extreme precision and size tolerance. They are critical components for ships, marine platforms, aerospace equipment, hydraulic systems, and chemical injection pipelines.
Equipped with advanced high-speed precision multi-roll mills and bright annealing furnaces, we achieve superior diameter tolerances up to 0.3%D and wall thickness tolerances up to 3%S. This precision ensures seamless integration with high-density card sets and cutting sleeves.
The bright annealing process is conducted in a closed furnace protected by argon and nitrogen. This prevents oxygen exposure and oxide skin formation, keeping both the internal and external surfaces bright and clean. Our accurate temperature control (within ±5ºC) ensures uniform mechanical performance for bending and reaming.

❓ Frequently Asked Questions
What are the primary applications for these seamless tubes?
They are widely used in shipbuilding, marine platforms, aerospace equipment, hydraulic systems, chemical injection pipelines, and oil/gas drilling.
What level of dimensional tolerance can your pipes achieve?
Our advanced multi-roll mills allow us to achieve diameter tolerances up to 0.3%D and wall thickness tolerances up to 3%S.
What are the advantages of your bright annealing process?
Using a closed furnace with argon and nitrogen protection prevents oxidation. This keeps the pipe surfaces bright and clean while ensuring uniform mechanical properties for bending.
Which specialized materials do you offer besides standard stainless steel?
We supply Super Austenitic (904L), Super Duplex (2507), Nickel Alloys (C276, 625, 800), and various Titanium alloys (GR1, GR2, GR5).
What is the maximum length of seamless pipe you can produce?
We can produce seamless pipes with a maximum length of up to 38 meters.
What quality testing procedures are in place?
We use a full suite of testing equipment, including direct-reading spectrometers, ultrasonic fault detectors, eddy current flaw detectors, and hydrostatic test machines.
