DIN 2617 Pipe Caps for Durable Pipeline Sealing and Corrosion Protection

DIN 2617 pipe caps are precision-engineered butt-welded fittings designed to seal pipe ends, providing exceptional protection against corrosion, environmental exposure, and pressure loss. These caps are vital for boiler pipeline protection and corrosion resistance in industries such as oil and gas, petrochemical, power generation, and chemical processing.

Compliant with DIN 2617 standards, these pipe caps are available in sizes from DN15 to DN300, with wall thicknesses up to 200 mm for demanding applications. They are crafted from materials like carbon steel (HII, P235GH), stainless steel (1.4541, 1.4571), and alloy steel (15Mo3, 13CrMo44, 10CrMo910), ensuring durability and resistance to corrosion. Protective coatings such as galvanization, pickling, or Fusion Bonded Epoxy (FBE) enhance performance in harsh environments.

DIN 2617 pipe caps undergo rigorous testing, including chemical analysis (e.g., HII: C ≤0.16%), tensile testing (yield strength ≥235 MPa, tensile strength ≥360-510 MPa for HII), hydrostatic testing (up to 9.8 MPa), and nondestructive methods (radiographic, ultrasonic, PMI). With a carbon steel density of ~7.85 g/cm³ and suitability for temperatures up to 450°C, these caps excel in high-pressure piping systems like boilers, heat exchangers, and refinery pipelines.

The butt-welded design ensures a secure, leak-free seal, making DIN 2617 pipe caps ideal for terminating pipelines and protecting against erosion/corrosion in challenging industrial settings, such as offshore platforms and chemical plants.

What is DIN 2617?

DIN 2617 is a German standard for butt-weld pipe caps, specifying the dimensions, shapes, and materials for caps intended to be welded onto the end of a pipe. These caps are crucial for sealing pipeline ends, providing a secure, liquid- and gas-tight closure.

DIN 2617 pipe caps are essential butt weld fittings designed for sealing the ends of pipelines and pressure vessels in demanding industrial environments. These closures, often specified as ellipsoidal heads or dished ends, provide a robust and secure seal against pressure, contaminants, and leaks. Manufactured to the precise standards of DIN 2617, our fittings ensure dimensional accuracy and consistent performance across a wide range of applications

The standard includes tables detailing specific dimensions, such as the outside diameter, wall thickness, and height.

FAQ

DIN 2617 pipe caps are butt-welded fittings used to seal pipe ends, ensuring corrosion resistance and reliable sealing for boiler pipeline protection in petrochemical, power generation, and chemical processing systems.

DIN 2617 pipe caps are butt-welded fittings (DN15-DN300) for pipe ends, offering secure sealing. DIN 28011 pipe caps are torispherical heads for pipes or vessels, designed for stress distribution, with similar corrosion resistance but different geometries.

DIN 2617 pipe caps are made from carbon steel (HII, P235GH), stainless steel (1.4541, 1.4571), or alloy steel (15Mo3, 13CrMo44, 10CrMo910), with coatings like FBE or galvanization for corrosion resistance.

DIN 2617 pipe caps are produced via: - Seamless Forming: For uniform structure.
- Welded Fabrication: For larger sizes.
- Cold Pressing: For precise shapes.
- Hot Forming: For thicker caps.
These ensure corrosion resistance and reliability.

Key benefits include: - Corrosion Resistance: FBE, galvanization, or 3LPE coatings.
- Leak-Free Sealing: Butt-welded for secure termination.
- High-Pressure Durability: Handles ≥9.8 MPa.
- Cost-Effectiveness: Affordable for boiler pipeline protection.

DIN 2617 pipe caps range from DN15 to DN300 (seamless: 1/2″ to 48″, welded: 24″ to 72″), with wall thicknesses up to 200 mm, suitable for industrial piping.

Quality is ensured through: - Chemical Analysis: Verifies composition (e.g., C ≤0.16% for HII).
- Tensile Testing: Confirms strength (YS ≥235 MPa, TS ≥360-510 MPa for HII).
- Hydrostatic Testing: Verifies pressure integrity (≥9.8 MPa).
- Nondestructive Testing: Radiographic, ultrasonic, PMI.
These ensure corrosion resistance and durability.

Weight is calculated using: Weight (kg) = [π * (D - t) * t * h * ρ / 1000], where D is the outer diameter, t is wall thickness, h is height, and ρ is density (~7.85 g/cm³ for carbon steel).

Applications include: - Power Generation: Boiler pipeline protection.
- Petrochemical: Oil and gas pipeline sealing.
- Chemical Processing: Corrosive fluid pipeline termination.
- Offshore Platforms: Seawater and acid-resistant piping.
These benefit from corrosion resistance.

Welding requirements include: - Preheating: 100-150°C for walls >10mm.
- Filler Materials: AWS A5.1 E7018 for carbon steel, or equivalent for stainless/alloy steel.
- Post-Weld Heat Treatment: Stress relief at 600-650°C.
These ensure welds for boiler pipeline protection.
