DIN 1626 St37 Cold Drawn Seamless Steel Pipe Carbon Steel Tube For Low Temperature Pressure

DIN 1626 St37 St44 St37 St42 St45 Cold Drawn Seamless Steel Pipe Carbon Steel Tube For Low Temperature Pressure

Introduction

DIN 1626 is a standard that specifies the requirements for cold drawn seamless steel pipes made from carbon steel, particularly designed for low-temperature pressure applications. This article provides an overview of the material specifications, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades.

Material Specification

The DIN 1626 standard covers various grades of carbon steel pipes, including St37, St44, St42, and St45. These materials are characterized by their excellent mechanical properties and suitability for low-temperature environments.

Key Features

  • Seamless Construction: Ensures uniformity and strength.
  • Cold Drawn: Enhances dimensional accuracy and surface finish.
  • Low-Temperature Resistance: Suitable for applications in cold environments.
  • High Strength: Capable of withstanding high pressure.

Chemical Composition

Steel Grade C (%) Si (%) Mn (%) P (%) S (%)
St37 0.17 0.25 1.20 0.045 0.045
St44 0.20 0.25 1.40 0.045 0.045
St42 0.20 0.25 1.20 0.045 0.045
St45 0.25 0.25 1.60 0.045 0.045

Mechanical Properties

Steel Grade Yield Strength (MPa) Tensile Strength (MPa) Elongation (%)
St37 235 360-510 26
St44 275 410-550 24
St42 245 400-550 22
St45 295 450-600 20

Steel Grade

The primary steel grades covered under DIN 1626 include:

  • St37: Low carbon steel, good weldability.
  • St44: Medium carbon steel, higher strength.
  • St42: Similar to St37 but with improved mechanical properties.
  • St45: Higher carbon content, suitable for more demanding applications.

Application

DIN 1626 seamless steel pipes are widely used in various industries, including:

  • Oil and Gas: For pipelines and pressure vessels.
  • Chemical Industry: In reactors and heat exchangers.
  • Construction: Structural applications requiring high strength.
  • Cryogenic Applications: Suitable for low-temperature environments.

Possible Alternative Grades

In addition to the specified grades, the following alternative grades may be considered based on specific requirements:

  • ASTM A106: Standard specification for seamless carbon steel pipes for high-temperature service.
  • ASTM A53: Standard specification for pipe, steel, black and hot-dipped, zinc-coated, welded, and seamless.
  • EN 10216: European standard for seamless steel tubes for pressure purposes.
