ASTM A53 is the 'Standard Specification for Black and Hot-Dipped, Zinc-Coated, Welded and Seamless Steel Pipe' established by the American Society for Testing and Materials (ASTM), primarily used in pressure piping and mechanical structure fields.
This standard is issued under the fixed designation A500/A500M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (ε) indicates an editorial change since the last revision or reapproval.
Applicable to: construction, machinery manufacturing, photovoltaic, furniture, special vehicle frame manufacturing, container manufacturing, decoration, etc.
This standard specifies the manufacturing requirements for seamless and welded pipes for pipeline transportation systems in the petroleum and natural gas industries, including two product specification levels (PSL1 and PSL2). This specification does not apply to cast iron pipes.
Line Pipe for Petroleum and Natural Gas API SPEC 5L
This standard specifies the manufacturing requirements for seamless and welded pipes used in pipeline transportation systems for the petroleum and natural gas industries, including two product specification levels (PSL1 and PSL2). This specification does not apply to cast iron pipes.
EN39 Hot-Dip Galvanized Scaffolding Steel Pipe
EN39 scaffold steel pipes are steel pipes produced according to the European standard EN39 for building scaffolding.
Fence made of galvanized steel pipe
Galvanized steel pipe is a common material used for making fences. It is treated through a galvanizing process on ordinary steel pipes to provide good corrosion resistance.
Elliptical steel pipes are a new type of greenhouse frame material, widely used in modern greenhouse construction due to their unique structure and performance advantages.
Photovoltaic BIPV Waterproof System
BIPV (Building Integrated Photovoltaics) is a technology that integrates solar photovoltaic modules with building envelopes (such as roofs, curtain walls, sunshades, etc.). Its core is to allow photovoltaic modules to simultaneously undertake the dual functions of "power generation" and "building envelope". The waterproofing system is a key subsystem of BIPV, which is directly related to building structural safety (preventing water leakage from damaging the building), photovoltaic module life (avoiding moisture and short circuits), and power generation efficiency (reducing downtime due to failures).
Steel pipe connecting rod (pre-galvanized steel pipe)
The galvanized connecting rod used in greenhouses is an important accessory for connecting various parts of the greenhouse frame.
Angle Chi photovoltaic integrated tile
Standing seam photovoltaic integrated tile is a new type of building material that combines photovoltaic power generation with roofing tiles.
Hot-rolled H-beam is an economical and efficient section steel with a cross-sectional shape similar to the English letter "H". It is formed by rolling steel billets through a rolling mill at high temperatures.
Hot-rolled I-beams (also known as I-beams) are hot-rolled steel with an "I"-shaped cross-section. They have the advantages of strong bending resistance, good structural stability, and light weight, and are widely used in many fields.
Zinc magnesium aluminum guide rail
The zinc-magnesium-aluminum cold-formed guide rail is a guide rail product made of zinc-magnesium-aluminum alloy strip through cold-forming process. It has both the material advantages of zinc-magnesium-aluminum alloy and the forming characteristics of cold-forming process. It has unique advantages in structural stability, processing efficiency and application scenarios. It is currently mainly used in the photovoltaic industry and is expected to enter more markets in the future.
As a high-precision agricultural facility, glass greenhouses have extremely high requirements for structural stability, and ground anchors are a key component to ensure their resistance to external forces such as strong winds and snow accumulation.
