Product catalog summary
Special Parts and Orbital Welding
This section details the collaboration with customers for the development and production of special parts, even in small quantities. Production is conducted in specialized facilities, ensuring quality through modern measurement techniques. It highlights the use of special materials, custom fittings, adapters, and welded assemblies. The construction department designs pipe connection elements based on customer specifications, adapting to changing conditions as needed. Testing facilities can perform static and dynamic pressure tests up to 4000 bar, documenting changes with video technology.
Orbital Welding
Orbital welding is a fully automated, computer-controlled process based on the TIG welding principle. The electrode moves around the parts to be welded, with parameters like welding current and speed defined in a program. Protective gas is used to ensure high-quality weld seams. This section offers the capability to manufacture individual components or complete piping systems per customer specifications.
Thread Sizes and Types
This section provides detailed information on various thread sizes and types, including NPT, R, UNF, and G threads. It emphasizes the importance of sealing through the pressing of sealing surfaces outside the thread and includes tables with specifications for metric threads and Whitworth pipe threads.
Materials and Conditions
The document covers materials used in production and the conditions of sale and delivery, providing contact information for further inquiries.
Specifications and Standards
The document outlines standards for pipe fittings with tapered male studs and parallel tapped holes according to DIN 3852 Part 2, comparing them with DIN 2999 and ISO 228 to highlight differences in thread length and tolerance that reduce leak risks.
Thread Types
  • Whitworth Pipe Threads (BSP): Used for pipe fittings, sealing with material in the thread.
  • American Tapered Threads (NPT): Used for pressure-tight connections with sealing material.
  • UNF/UN Threads: Used for mechanical connections, not sealing on the thread.
  • Knuckle Threads (DIN 405): Used for non-sealing connections, resistant to damage.
Screwed Plugs and Tapped Holes
Describes different types of screwed plugs and tapped holes, including those with metallic and elastomer seals, providing detailed measurements and standards.
Materials and Additives
  • Aluminium (Al): Enhances aging resistance and scale resistance in steels.
  • Chromium (Cr): Increases hardenability and tensile strength but reduces weldability.
Overview
The document provides a detailed analysis of alloying elements in steel production, their effects on steel properties, and characteristics of different steel types. It includes tables summarizing physical and mechanical properties of specific steel grades and their applications.
Key Sections
  • Alloying Elements: Discusses the role of elements like Chromium, Carbon, and Nickel in steel, detailing their impact on properties.
  • Steel Grades and Properties: Provides data on physical and mechanical properties of various steel grades.
  • Chemical Composition: Outlines the chemical composition of different steel types.
  • Applications: Lists applications of various steel grades in industries.
  • Material Properties: Evaluates properties of gasket materials like NBR, EPDM, and PTFE.
Critical Information
  • Chromium: Essential for corrosion resistance, with a minimum of 13% required in steel.
  • Carbon: Increases strength and hardness but reduces ductility.
  • Copper: Improves weather resistance but can cause surface sensitivity.
  • Manganese: Enhances hardenability.
  • Nickel: Increases toughness and is used in austenitic steels.
  • Applications: Specific steel grades are recommended for different industrial applications.
Specifications
Provides information on the chemical resistance of various gasket materials, listing their suitability and limitations.
Material Suitability
  • NBR: Suitable for hydrocarbons and mineral oil, not for chlorinated hydrocarbons.
  • EPDM: Suitable for acids and alkaline media, not for hydrocarbons.
  • VMQ (MVQ): Suitable for gases and hot air, not for aromatics.
  • FKM (FPM): Suitable for hydrocarbons, not for ketones.
  • PTFE: Resistant to most chemicals, not suitable for certain compounds at high pressure.
Recommendations
When selecting gasket materials, consider the chemical environment and operating conditions to ensure compatibility and performance.

Instrumentation | High Tech Orbitalschweissen Orbital Welding Technische Informationen, í Orbitalschweissen Definition Das Orbitalschweissen ist ein vollautomatisches, computergesteuertes Schweissverfahren nach dem Prinzip des Wolfram-Inertgas-Schweissen (WIG). Hierbei wird die Elektrode auf einem Rotor um die zu verschweissenden Bauteile geführt. Schweisstrom, Schweissgeschwindigkeit und Nahtüberlappungen werden in einem Schweissprogramm definiert. Schweisskammer und Rohrinnenbereiche werden vor, während und nach dem Schweissen mit Schutzgas gespült. Daraus resultiert eine reproduzierbare Schweissnaht...
