Grades & Specs

Performance Under Pressure

The Kun Metal Seamless Advantage

Stainless steel seamless pipes offer distinct advantages over welded alternatives in critical applications:

01.

Superior Pressure Rating

No weld seam means uniform strength and structure, providing higher reliability under internal and external pressure compared to welded pipes.

02.

Enhanced Corrosion Resistance

The absence of a weld zone eliminates potential points for preferential corrosion, ensuring better performance in aggressive environments.

03.

Uniform Structure & Shape

Seamless manufacturing results in excellent uniformity in grain structure, roundness, and dimensional tolerances, crucial for precision fittings.

04.

High Temperature & Strength:

Ideal for applications involving elevated temperatures and demanding mechanical stress due to their inherent structural integrity.

Grades & Standards

Seamless Pipe Grades and International Standards

We supply stainless steel seamless pipes in various grades to meet specific application requirements, adhering to key international standards:

Advanced Manufacturing

Manufacturing Process

Our stainless steel seamless pipes are produced using advanced methods ensuring superior quality:

Hot Piercing / Extrusion

Solid billets are heated and pierced or extruded to form a hollow shell, creating the fundamental seamless structure.

Cold Drawing / Cold Rolling:

The hollow shell is further processed (often multiple times with annealing in between) to achieve precise dimensions, improved surface finish, and enhanced mechanical properties.

Heat Treatment:

Controlled annealing (solution annealing) is performed to relieve stresses, optimize corrosion resistance, and ensure the required material properties.

Quality Assurance

Quality Assurance & Testing

Stringent quality control and testing procedures guarantee the integrity of every pipe:

Non-Destructive Testing (NDT)

Includes Ultrasonic Testing (UT) and/or Eddy Current Testing (ET) to detect potential flaws without damaging the pipe.

Hydrostatic Testing

Each pipe is pressure tested with water to verify its ability to withstand operating pressures without leakage.

Dimensional & Visual Inspections

Thorough checks for Outer Diameter (OD), Wall Thickness (WT), length, straightness, and surface finish against specified tolerances.

Mechanical & Chemical Testing

Includes tensile tests, hardness tests, flattening tests, flare tests, and chemical composition analysis (Spectro) as per standard requirements.
