MS1462 steel pipe is the " Malaysian standard ", with the full name " MS 1462-2-1:2010 "Metal Scaffolding - Part 2: Tubular (pipe and joint) Scaffolding - Section 1: Steel pipe Specification" .
This standard is formulated for steel pipes used in construction scaffolding, clearly stipulating the materials, dimensions, performance and process requirements. The following are the specific contents:
I. Core Standard Requirements
1.Materials and Chemical Composition:
The steel pipe is made of non-alloy structural steel, with the grade of S235GT (similar to the European standard S235JR), and its chemical composition must meet:Chemical Composition Carbon (C) Silicon (Si) Manganese (Mn) Phosphorus (P) Sulfur (S) Properation ≤0.22% ≤0.35% ≤1.40% ≤0.045% ≤0.045%
This steel grade features excellent strength and weldability, making it suitable for the structural requirements of scaffolding.2. Size Specifications:
- Outer diameter: Fixed at 48.3mm (consistent with the internationally common size of scaffolding pipes).
- Wall thickness: Commonly available are 3.2mm and 4.0mm, with an allowable deviation of ±10%.
- Length: Usually 6 meters or customized length. Both ends need to be processed to be smooth and free of burrs.
3.Mechanical properties:Mechanical properties Tensile strength Yield strength Elongation: Requirement ≥360 MPa ≥235 MPa ≥25%
Steel pipes need to undergo tensile tests to verify the above-mentioned properties and ensure that no brittle fracture occurs under load.4. Process and Surface Treatment:
- Manufacturing Process : Hot rolling or cold drawing seamless process is adopted. Hydrostatic testing (pressure ≥5 MPa) or eddy current testing is required to ensure there are no cracks, holes or other defects.
- Surface treatment : Hot-dip galvanizing must be carried out, with a coating thickness of ≥85 μm, in compliance with EN 10240 standard, to resist outdoor corrosion and extend service life.
5. Marking and Acceptance:
Each steel pipe should be marked with the standard number (MS 1462-2-1:2010), outer diameter, wall thickness, production batch and other information.
A third-party test report is required to verify the dimensions, mechanical properties and the quality of the galvanized coating.II. Main Application Fields
MS1462 steel pipes are specially designed for construction scaffolding and are widely used in the following scenarios:
1. Construction of buildings
Build exterior wall construction scaffolding and internal support systems to provide workers with a safe working platform.
It is applicable to formwork support and protective structures for high-rise buildings, Bridges, tunnels and other projects.2. Temporary structure
The framework construction of large-scale event stages and exhibition display stands is facilitated by their standardized dimensions for quick assembly and disassembly.
Temporary load-bearing structures such as temporary storage shelves and maintenance passages.3. Industrial field
Equipment maintenance platforms in industries such as petrochemicals and power need to meet the requirements of corrosion resistance and load-bearing capacity.
It is used in conjunction with scaffolding joints of EN 74 standard (such as cross fasteners and turning fasteners) to form a stable working platform.III. Comparison with Other Standards
Chinese standard GB/T 8162 :Mainly used for mechanical structures or general engineering, with no specific design requirements for scaffolding, and galvanization is not mandatory.
European Standard EN 39:Compatible with MS 1462. Scaffolding materials imported from Malaysia often need to comply with both of these standards simultaneously to ensure international universality.\
IV. Precautions for Use
Steel pipes need to be regularly inspected for the integrity of the galvanized coating. If rust is found, it should be repainted or replaced in a timely manner.
Overloading is strictly prohibited. The erection height and span must comply with local building codes (such as UBBL 1984 in Malaysia).
When used in combination with other types of scaffolding (such as bowl buckle type and wheel buckle type), the reliability of the connection nodes needs to be verified.Through the above requirements, MS1462 steel pipes ensure the safety and durability of scaffolding in construction and are one of the mainstream choices in the construction industry in Southeast Asia.
