About 350mm pvc drainage pipe

Types of 350mm PVC drainage pipe

Pipe dimensions are vital since they determine the degree of fluid that's effectively passed through the piping system. In terms of measures, 350mm PVC pipes represent a medium size in the drainage pipe hierarchy. The PVC drainage pipe types are as follows:

  • Standard Schedule 40 PVC Pipe: The standard Schedule 40 PVC pipe is the most widely used in many industries. Its 350mm diameter and generally accepted thickness allow it to manage decent drainage loads, although it cannot handle as much pressure as the thicker schedules. Its remarkable flexibility, affordability, and anti-corrosion properties are some characteristics that make this pipe relatively easy to install.
  • Schedule 80 PVC Pipe: When more limited areas are needed for more major pipelines or commercial use, the Schedule 80 PVC pipe may be more appropriate. Compared to the Schedule 40, its 350mm size pipe wall is thicker, thus better fitting higher-pressure tasks. Hence, the thicker wall means lower flow capacity due to the right size of the opening.
  • Soil and Waste (SW) PVC Pipe: The 350mm PVC drainage pipe designed for soil and waste evacuation differs from other drainage pipes as it is mainly constructed for use in such conditions. It is generally used in low-pressure situations where the transport of waste materials, especially water, requires a pipe. Its color, mainly orange or white, sets it apart visually, and its most common application is in the drainage systems of buildings.
  • Expanded Cell PVC Pipe: Expanded cell PVC pipes differ from regular PVC pipes in that they contain a foam core that makes them lighter without losing crucial strength. It is commonly used where the convenience of transportation and installation are of the essence, and in drainage applications, a 350mm EPVC pipe may have its uses in low to medium pressure situations.

How to choose 350mm PVC drainage pipe

Several factors need to be given attention before a 350mm PVC drainage pipe is selected since its effectiveness and longevity in drainage systems depend more on the quality material pipe and required conditions where it will be operated, among others.

  • Purpose and application: Determine the area where the pipe will be used and the type of drainage system it will support. Standard PVC pipes are good for most surface and underground drainage activities. Still, thicker-walled pipes, such as Schedule 80 or other types, should be used in areas that need higher pressure or more serious conditions.
  • Compatibility: Check how compatible the pipe is with other materials in the system. If the drainage system incorporates some metal or other types of plastic, ensure the 350mm PVC pipe is compatible with them. The 350mm SW pipes are for such drainage systems where perfect matches are required, especially those dealing with soil and waste.
  • Quality and standards: Confirm the quality of the PVC drainage pipe to ensure it meets the set standards. Such ensures that the pipe can withstand harmful UV radiation, chemicals, and extreme temperatures to help in drainage. Using pipes that conform to national or international standards ensures safer applications with lower risks.
  • Installability: Evaluate how easy it is to install the pipe before purchasing it. A drainage pipe of 350mm diameter and thickness can be installed more easily compared to a 350mm pipe made of other metals, especially if materials are to be fused together. For many drainage activities, the shape smooth and twists of the hole in the flow duct are crucial to the ease of installation and the time saved.
  • Cost: Finally, check the budget depending on the price of various pipes. Even though PVC drainage pipes are relatively cheaper, some types may still be pricier than others. Ensure the type selected suits the requirements without exceeding the budget.

Specifications and maintenance of 350mm PVC drainage pipe

Many drainage pipes possess 350mm PVC pipes' specifications, including diameters, length, standards, and wall thickness. Proper maintenance of drainage pipes constantly assures their long-lasting existence and efficiency in doing their allocated functions.

Technical specifications:

  • Diameter: The diameter of a 350mm PVC drainage pipe is 0.35 meters, making it suitable for medium-sized water passage systems.
  • Materials: PVC is a synthetic plastic polymer material that is highly resistant to corrosion, water, and a large number of chemical substances.
  • Wall thickness: The thickness of the wall of the pipe is determined by the schedule number or type of pipe, with the thicker types providing better pressures and larger carrier system capabilities.
  • Length: PVC drainage pipes are typically available in standardized lengths of approximately 4, 6, and 9 meters, though the exact length might differ based on the manufacturer.
  • Temperature range: PVC pipes best function at temperatures ranging from -10 to 60 degrees. Outside this range, especially at the upper limit, the pipe may lose its properties or even degrade.
  • Joint type: A 350mm drainage pipe commonly employs socket joints, whereby the pipes are fixed in place using solvent cement to create a tight, properly sealed-fitting junction.

Maintenance tips:

  • Regular inspections: Undertake regular inspections on the drainage pipes when possible. Look out for visible signs of deterioration, cracks, or leaks on the pipe surface. Any such symptoms usually offer a clue that may lead to changes in behavior, such as inefficient drainage, which needs timely fixing to prevent further development of drainage problems.
  • Clear blockages: If it is a wooden block or anything, avoid introducing any materials into the drainage system that would cause a blockage. If any materials find their way into the drainage system, remove them immediately. Blockages can cause pressure build-up in the drainage pipes that may result in bursting or cracking pipes, especially at their thinnest part.
  • Proper drainage: Always confirm that there are no pools of water around the drainage pipes. Water pooling around pipes can facilitate temperature variations that can trigger pipe expansion or contraction, leading to cracks in the drainage pipes.
  • Avoid high heat: Do not introduce substances that are highly heated through PVC drainage pipes since this can threaten pipe integrity by softening the plastic. Ensure any liquid that runs through the pipe is cool to touch.
  • Repairs: Small issues, such as tiny cracks or leaks, should be addressed on time. Use appropriate repair compounds and sealants designed specifically for PVC to fix the pipe where necessary. Do not leave such minor problems unattended, as they may escalate and warrant complete pipe replacement and a lot of inconveniences in drainage.

Benefits of 350mm PVC drainage pipe

A 350mm PVC drainage pipe can relieve a few pressures in a drainage system because it is cost-efficient and healthily lightweight while remaining quite resistant to corrosion. The orange drainage pipe has a number of advantages, including:

  • Lightweight: Compared to other materials like metals, the 350mm PVC pipe is extremely lightweight, easier to handle and transport, and does not require heavy equipment for its installation. Its lightness can make the whole process run faster and easier.
  • Corrosion resistance: PVC has high resistance to corrosion and rust, allowing it to carry substances without fear of degradation within or without the pipe due to the chemical content of the liquid or moisture outside the pipe.
  • Cost-effective: A 350mm PVC drainage pipe is a relatively cheaper option in the drainage systems. The materials and installation costs are cheaper than metal or other drainage pipes.
  • Durability: Even though PVC pipes are relatively thinner than their metal counterparts, they provide longer service. The orange drainage pipe has enough tensile strength to withstand external pressure and significant strain. Besides, it's not as pricey as other pipes: iron, steel, or brass.
  • Easy installation: The drainage pipes use a 'hub and spigot' joint system, a special system that offers practical applications in the installation or connection of pipes. The installation doesn't require complex welding or sealing methods, hence saving time and possibly extra installation costs.
  • Flexibility: PVC is different from other pipe materials, like cast iron, because it is nonrigid and hence can be molded into different shapes and sizes. As such, this material can be used for different kinds of drainage systems.
  • Noise reduction: PVC is quieter, meaning that water flow through it generates less noise than most drainage pipes, particularly metal ones.
  • Smooth interior surfaces: The interior surfaces of 350mm PVC pipes are smooth and, therefore, easier for the flowing liquid. The smoothness limits the chances of blockage as there would be none of the accumulation of deposits on the pipe's inner surfaces.
  • Resistance to UV: PVC pipes have great resistance to harmful rays from the sun, meaning they can also stay outdoors in good order even after prolonged exposure to sunlight.
