Marine plastic water tanks

Types of marine plastic water tanks

Marine plastic water tanks are essential on boats and ships for fresh water storage. They come in various materials and designs to meet different needs. Here are the main types:

• Polyethylene water tanks: These are the most common water storage tanks on boats and ships. They are affordable and lightweight. Polyethylene is a durable material that does not corrode. These marine plastic water tanks also have smooth inner surfaces that reduce bacteria growth in stored water. They come in different shapes and sizes to fit various boat spaces. However, prolonged sun exposure can make the plastic brittle. To counter this, these tanks can be coated with UV-resistant paint.
• Fiberglass water tanks: Fiberglass is another popular material for marine water tanks. Fiberglass water tanks are more robust than polyethylene ones. They also resist corrosion from seawater and chemicals. These tanks can be molded into complex shapes, maximizing space on ships. For example, a fiberglass water tank can have a rectangular shape to fit a corner. Additionally, fiberglass water tanks have smooth surfaces that are easy to clean. However, they are more expensive than plastic tanks.
• Stainless steel water tanks: Stainless steel is a traditional material for marine water tanks. Stainless steel is very durable. It can handle high pressure, making it ideal for large water storage tanks. For example, ships that travel long distances use large stainless steel water tanks to store the water needed for the journey. Stainless steel also resists rust and corrosion from seawater. However, these marine water tanks must be regularly cleaned to prevent limescale buildup.
• Aluminum water tanks: Aluminum is lightweight and resistant to corrosion. Aluminum water tanks are suitable for both freshwater and wastewater storage on large ships. They can be constructed in custom sizes and shapes to fit available spaces. For example, an aluminum water tank can be made in a cylindrical shape to fit a ship corner. Aluminum tanks also have a long lifespan. However, they are more expensive than polyethylene and fiberglass tanks.
• Composite water tanks: These tanks combine different materials to leverage their strengths. For example, a composite tank may have a fiberglass shell with a polyethylene liner. This makes the tank strong and ensures a smooth inner surface. Composite tanks can be customized to meet specific needs, such as particular shapes and sizes.

Specifications & Maintenance of Marine Plastic Water Tanks

Marine water tanks come in different specifications to meet various needs. Here are some of them:

• Capacity

  Marine plastic water tanks have different sizes depending on the available space and intended use. Some range from 50 to 1000 liters.

• Dimensions

  Marine plastic water tank dimensions are designed to ensure a perfect fit in the intended space. They include diameter, height, and tank shape.

• Shape

  Plastic water tanks can be round, rectangular, or cylindrical. The design is to optimize the available space and ensure structural stability.

• Wall Thickness

  The wall thickness of marine water tanks varies. Some are 5mm to 20mm depending on the tank size. The thickness affects the tank's strength and durability.

• Connection Size

  Marine water tank connections are designed to facilitate the attachment of pipes and fittings. The connection size varies from 10mm to 50mm.

• Color

  Marine tanks are available in different colors such as blue, black, and green. The color choice depends on the purpose such as UV protection and aesthetics.

• Additives

  Some marine plastic water tanks have antimicrobial additives that inhibit bacteria growth. Others have UV stabilizers that protect against sunlight degradation.

Marine plastic water tank maintenance is key in ensuring longevity and reliability. Here are some of them:

• Regular Inspection: Users should regularly check the water tanks for signs of wear and tear, cracks and leaks. Also, inspect the fittings, valves, and pumps for proper functioning.
• Cleaning: Over time, marine plastic water tanks get dirt and biofilm build-up which can affect water quality. Therefore, they should be washed regularly with a soft brush and mild detergent. Also, rinse thoroughly to avoid residue.
• Algae and Biofilm: Users can prevent biofilm and algae growth by adding chemical treatments such as chlorine. They can also add a UV light system in the tank to kill the microorganisms.
• Water Quality Testing: Regularly test the water in the tanks to check if it meets the required standards. The tests should check for parameters such as pH, chlorine levels, and microbial contamination.
• Tank Positioning: The tank should be in a place that is away from direct sunlight. This helps to minimize plastic degradation and prevent algae growth.
• Drainage and Ventilation: Adequate drainage and ventilation in the marine plastic tank help to reduce humidity. This minimizes the chances of algae and biofilm growth.

How to choose marine plastic water tanks

Choosing a suitable water tank for a vessel is a crucial decision for any retailer. Here are some factors to consider when choosing marine plastic water tanks for sale:

• Space availability

  Consider the space available in the boat or ship to avoid water tank congestion. The dimensions and shape of the marine water tank should fit perfectly in the intended space.

• Water tank capacity

  Water tanks for marine use come in different sizes. Choose a tank that will satisfy the customer's needs without unnecessary refills. However, overfilling may cause water tank congestion and overflow during turbulence.

• Maintenance and inspection

  Choosing a tank that requires minimum maintenance is wise. Also, ensure that the tank is easily accessible for inspection and cleaning. Consider water tanks with inspection ports and access hatches.

• Tank shape

  Water tanks come in different shapes, including rectangular, cylindrical, and oval. The tank shape for a specific vessel depends on the available space and mounting preferences. For example, cylindrical tanks are ideal for rounded areas.

• Weight

  Choosing a lightweight tank is wise to avoid waterlogging and overburdening the vessel. However, the tank should be robust and resistant to movements and waves.

• Code compliance

  Consider water tanks that meet the relevant marine standards and codes. For example, the tank should be constructed using food-grade materials to avoid water contamination.

• Budget

  Choose a water tank that will suit the customer's needs and pocket. However, prioritize quality over affordability.

How to Replace Marine Plastic Water Tanks

Replacement of marine water tanks can be a challenging task. However, with the right tools and knowledge, this task can be done. Below are the steps to be followed:

Before starting the process, here are some tools that will be needed:

• Hacksaw
• Screwdriver
• Drill
• Tape measure
• Wrench
• Tank replacement
• New fittings and valves
• Hose clamps

Steps to Follow

• 1. Turn off the water supply and drain the tank.
• 2. Remove all the fittings and valves from the old tank.
• 3. Use a hacksaw to cut the tank into manageable pieces.
• 4. Remove the tank from the boat.
• 5. Install the new tank and reconnect all the fittings and valves.
• 6. Turn on the water supply and check for leaks.
