Pipes are materials that offer a plethora of benefits for people who work on construction projects. These act as framework reinforcements for water supply, heating, proper sewage disposal, and the provision of clean drinking water. When it comes to buying from a steel pipe supplier in the Philippines, it is important that you know about the things to consider when buying pipes.
Most workers prefer to use pipes for both residential buildings and major infrastructures because they are easily customizable. To help you make an informed decision, here are some of the considerations when buying pipes.
No matter how small or big a leak is, some form of pipe damage is bound to occur. Besides the potential of leaks, water pressure is a force that every pipe will have to cope with. High water pressure can lead to wide-scale damages. Arguably, abrasive materials that pass through the pipes will eventually degrade their quality.
You will have to buy pipes that are made with materials suitable for the purpose of installation. Moreover, the pipes should withstand forces that will be dealt with on a daily basis. Steel is often an ideal material for pipes. The construction industry relies on steel pipes for its durability.
Given that pipes are responsible for transporting liquids from one point to another, their interiors tend to be vulnerable to corrosion. Corrosion refers to the deterioration process of materials because of a reaction to the environment. Generally, most metal components corrode because of acidity and oxidation.
When highly acidic substances come into contact with steel pipes, rust accumulates inside its layers. This results from oxidation, which means losing iron particles to acidic electrolytes. The water pressure coming from the pipes can further enforce both chemical reactions.
In the long run, the pipes will be destabilized due to corrosion. This factor is naturally occurring and can happen at any rate. Thus, it would be best to buy a pipe that has strengthened corrosion protection. Galvanized pipes are manufactured to resist corrosion. These pipes have been dipped in a protective zinc coating to prevent the metal from rusting. In addition, it prevents the buildup of deposits that can clog the pipeline.
Tensile strength refers to the maximum capacity that a material can withstand forces before failure or breaking. A strong material can have tensile stress push against it and will just end up becoming flat. This will protect the material from being damaged permanently.
If you plan to buy from a steel pipe supplier in the Philippines, your products must have the best tensile strength to ensure they last for a long time. As versatile construction materials used in a wide variety of applications, pipes will deal with extreme loads and other environmental factors.
With a high-quality black iron pipe, you are assured of reliable tensile strength. These pipes are typically cast from mild grades of steel. With less carbon, they possess an ideal property of ductility and malleability.
Various pipe companies were able to manufacture metal sheets to become spiral in shape. Instead of shattering completely, they have been heated and cooled to act as protection from brittleness. While the metal is still hot, its ends are bent to make a tube without breaking.
When you purchase pipes, they should be able to adjust to all kinds of harsh environments. Ideally, they must withstand extreme cold and hot temperatures.
The cold weather can often make metal components brittle. The water pressure begins to rush through the pipe and ice forms. If left unnoticed, steel pipes can burst and rupture because of ice blockage. Depending on the scale of damage, it can be especially costly to repair or even require a total replacement.
On the other hand, hot temperatures can make pipes break for a distinct reason. Direct heat can cause the metal to expand. In thermal expansion, the length, surface area, and volume of materials will increase, which makes them more prone to issues and decreases their lifespan. Once the pipe cannot handle the extreme heat, it will also rupture.
Naturally, environmental factors cannot be controlled. The best course of action would be to invest in pipes made with durability in mind. Steel pipes will maintain their form despite temperature fluctuations because they are designed to be highly durable.
Pipes are on-demand materials used for a plethora of applications. To help with your purchasing decision, remember these four things to consider when buying pipes.

American Society for Testing and Materials, or ASTM, sets industry-wide standards for materials, including structural steel. These standards address chemical composition, mechanical properties, and manufacturing processes.
Complying with ASTM standards ensures that the steel meets the requirements for quality and safety. Compliance is often a prerequisite for projects, especially in regulated industries like construction and aerospace.
The International Organization for Standardization (ISO) provides recognized certifications for various products and materials, including steel.
ISO certification indicates that the steel has met international quality benchmarks, making it suitable for projects that span different countries or must follow global standards.
Custom standards might be developed for specialized projects or applications with unique requirements not covered by existing standards. Military projects, specialized research facilities, or unique architectural designs may require custom standards.
Countries or regions may have their standards, which could be adaptations of international standards or independently developed guidelines. Examples are European EN standards and Japanese JIS standards.
Local or national standards may be mandatory for projects within specific jurisdictions, and checking for Compliance when sourcing structural steel is advisable.
Often accompanies the product to certify that it meets the claimed standards. Independent entities may be hired to verify that the structural steel complies with all required standards.
Failure to comply with quality certifications and standards can lead to legal consequences, including fines and project delays. Contracts often specify the quality standards to be met, and not complying with these could be a breach of contract.
Tensile strength indicates how well a material can resist being pulled apart. It is an important factor in applications where materials will undergo tensile pressures. Usually measured in megapascals (MPa) or pounds per square inch (psi). For example, tensile strength is a key parameter in skyscraper construction, where steel has to support huge vertical loads.
Yield strength defines the maximum stress that can be applied to the steel before it deforms permanently. In construction, this is especially important for ensuring structural integrity. It’s usually measured in megapascals (MPa) or pounds per square inch (psi). Bridges, for instance, require steel with high yield strength to endure dynamic loads like heavy traffic and wind forces without deforming.
Hardness measures the resistance to deformation and is usually quantified using scales like the Rockwell or Brinell hardness scales. A higher hardness often indicates better wear resistance, which can be advantageous in applications like machinery components. In industrial machinery, harder steel can provide a longer lifespan for components like gears or shafts.
Ductility describes how much a material can deform under tensile stress before breaking. Higher ductility can absorb more energy during deformation, making it valuable in earthquake-prone regions. Buildings in seismic zones often use steel with higher ductility to withstand the forces of an earthquake.
Fatigue strength is the maximum stress a material can endure for several cycles without breaking. This property is particularly relevant in structures that experience repeated loading and unloading, like bridges or aircraft. For example, the steel used in aircraft landing gears needs high fatigue strength to endure repeated landings.
Weldability refers to how well the material can be joined through welding without compromising its properties. Poor weldability can introduce weak points in the structure, compromising its integrity. High weldability can simplify construction and improve final quality in large projects where pieces are often welded on-site.
The thickness of structural steel directly affects its ability to withstand loads and stresses. Insufficient thickness can result in structural failure or a shorter material lifespan. Industry standards often define a narrow range of acceptable thicknesses. Going beyond these tolerances can compromise the structural integrity. Regular inspections using calipers or ultrasonic thickness gauges can help ensure the material falls within acceptable tolerances.
Exact dimensions in length and width are often necessary in construction planning, where every inch can matter. Any changes can affect everything from fit to the ability to make secure connections. Just like thickness, the length and width of structural steel are regulated by industry standards. Not following these can result in ill-fitting components, leading to project delays. Ruler tapes, laser distance measurers, and even traditional yardsticks can be used depending on the required level of accuracy.
The weight of the structural steel plays a big role in transportation costs. Exceeding weight tolerances might require specialized transportation methods, which can be costly. Weight directly impacts the ease of assembly. Heavier pieces might need more advanced lifting equipment or labor, increasing the project’s complexity and cost. Weighing scales with high precision are generally used to ensure the material falls within the specified weight tolerances.
