Attribute Specification Details
Product Name 2507 Seamless Hydraulic Instrumentation Tube
Material Grade Super Duplex 2507 (UNS S32750 / 1.4410)
Standard ASTM A789 / ASME SA789, EN 10216-5
Outer Diameter (OD) 6.0 mm - 50.8 mm (1/4" - 2")
Surface Finish Bright Annealed (BA), Polished
PREN Value ≥ 40 (Excellent Pitting Resistance)
Certification
PED / ISO / AD2000
Material Properties
2507 Super Duplex stainless steel is engineered to withstand exceptionally demanding corrosive environments. Compared to standard 2205 duplex steel, 2507 exhibits higher chromium, molybdenum, and nitrogen content. Its pitting resistance equivalent number (PREN) exceeds 40, providing outstanding resistance to pitting and crevice corrosion in chloride-laden marine environments, acidic oil and gas fields, and high-temperature, high-pressure conditions.
Furthermore, its yield strength is more than double that of standard 316L austenitic stainless steel. This allows for thinner walled tubing in high-pressure hydraulic system designs, effectively reducing overall equipment weight and system costs.


Quality Control System
Addressing the extreme precision demands of hydraulic systems, SMLSCO implements a stringent 'zero-defect' quality control system exceeding industry standards:
  • 100% Non-Destructive Testing: Every hydraulic tube undergoes 100% eddy current testing (ET) or ultrasonic testing (UT) prior to dispatch, ensuring no hidden cracks or defects within the tube wall.
  • High-Pressure Testing Assurance: Rigorous hydrostatic or pneumatic pressure testing verifies the pipes' stability under high-pressure hydraulic conditions, eliminating leakage risks.
  • Precision Dimensional and Surface Control: Strict tolerances for outer diameter and wall thickness are maintained, with internal surface roughness (Ra) controlled within industry-leading standards, ensuring residue-free, low-friction fluid transmission.


Application Scenarios
Owing to its exceptional mechanical strength and corrosion resistance, SMLSCO's 2507 seamless hydraulic tubing finds extensive application in the most demanding industrial sectors:
  • Hydraulic control lines on offshore oil platforms
  • Subsea umbilical systems and fluid transfer systems for deep-sea operational equipment
  • Heat exchangers and high-pressure reactors handling highly corrosive chemical media
  • High-pressure reverse osmosis systems in desalination plants
Our products effectively resist prolonged erosion from highly concentrated brine, ensuring stable, long-term equipment operation.
Frequently Asked Questions
Q1: What surface finishes are available for your 2507 tubes?
A1: Our standard 2507 hydraulic tubes are supplied in Bright Annealed (BA) condition, ensuring a smooth, clean inner surface free of scale and impurities. We can also provide polished surfaces upon request to meet specific aesthetic or sanitary requirements for instrumentation lines.
Q2: Can SMLSCO provide 2507 tubes for urgent project needs?
A2: Yes. Leveraging our 200+ tons of specialized stock in seamless tubes, SMLSCO offers rapid delivery. Standard sizes can be shipped within 2 weeks, significantly faster than the industry average, helping you meet tight project deadlines.
Q3: How do you ensure the quality of high-pressure hydraulic tubes?
A3: Quality is our priority. Every single 2507 tube undergoes 100% Eddy Current Testing (ET) and Hydrostatic Testing before shipment to ensure zero leakage risks.
