HDG Steel Water Tanks in Cape Town

Hdg water Tanks manufacturer in South Africa

HDG Steel Water Tank

HDG water tanks are made of pressed steel (Q235 Pressed Steel), and their surface is covered in a thick layer of protective zinc alloy. To stop rust and corrosion on the inside surface of the tank, a zinc coating is applied. Because of this, the tanks have a minimum 10-year lifespan and are extremely durable.

Depending on the needed coating thickness, different panel sizes are offered. The size and coating thickness have an impact on the pricing of the tanks.  An interior food-grade polyethene lining is frequently included with an HDG steel water tank in Pretoria to provide extra defence against rust and corrosion brought on by the water it holds. Additionally, the inside lining prevents zinc from leaking into the water and giving your drinking water a metallic flavour.

Components of Our HDG Water Tank

1. Materials

Hot dipped galvanized tank in Pretoria has a 90 m thick surface zinc coating that protects the tank from hostile conditions and corrosion. The galvanized pressed steel tank finds application in geological prospecting, industrial/manufacturing use, regulating tanks, condensate tanks, inflating water tanks for heating systems, and building water storage.

One of the greatest tank choices for heavy-duty and industrial use is a galvanized steel water tank, which ensures a longer lifespan and more durability than a traditional steel tank without coating.

2. Jointing Material

For all joints between the tank panel flange, non-toxic PVC foam shall be utilized.  PVC is a durable and long-lasting substance. Due to its high intensity, anti-corrosive qualities, and good chemical stability, it is frequently utilised in jointing materials. 

Abrasion resistance, strong mechanical properties, and longevity are three of PVC’s main engineering benefits for construction applications. It is a substance that has been around for more than 50 years and is both safe and environmentally friendly. In comparison to other upholstery materials, it has a lower formaldehyde content.

3. Flange Plate

Plate flanges are also known as simple flanges, flat flanges, and slip-on flanges. A plate flange is a circular, flat disc that is welded to a pipe’s end to enable bolting to another pipe. The two plate flanges are usually welded together with a gasket between them in fuel and water pipelines.

The plate flange, which will be used to make junctions and joints, will have bolt holes around it. The tank plates are pressed on four sides at an angle of 45 degrees and 90 degrees to the plate face using a combined double flange.

4. Stays and Cleats

All tanks must have stays supported along their sides and ends to maintain tank strength up to the maximum water level. Angles of mild steel are to be used to make the stays. Plates of mild steel are used to make cleats.

Great benefits can be obtained from steel angles, particularly in the areas of framing, reinforcement, decorative trimmings, brackets, etc. The inherent qualities of these alloys combined with low-alloy steel make these angle bars perfect for use in assembly and construction.

5. Bolts, Nuts and Washers

A washer is a thin plate with a centrally located circular hole. A threaded fastener, such as a bolt or nut, uses washers to distribute the weight. It is possible to apply a washer to protect and prevent looseness before driving a screw or bolt into a surface.

Additionally, the surfaces of the two connected elements are shielded from damage by the bolt head and nut. These nuts and bolts are excellent for plumbing solutions and offer strong structural support.

6. Tank Covers

Tank covers can be supplied flat, pitched, curved, welded, or bolted to meet specific needs. Standard features include an insect-proof vent and a manhole.  It’s a one-stop shop for everything from maintaining the ideal water temperature in all types of extreme weather to shielding the water tank from dust and insects, protecting the lead and keeping it closed, shielding the water tank from animals like monkeys, and protecting your family from harmful UV rays.

7. Water Level Indicator

Sensor probes are used by water level indicators to show the water level in a storage tank. These probes relay data to the control panel to set off an indicator or alarm. Similar to panels sprayed in glossy yellow paint with black markings, mechanical level indicators also have a PVC float, pointer, cable and reverse reading system.

8. Ladded

Most Hot-dipped galvanized tanks in Pretoria have a ladder for cleaning underground sub-tanks as well as for climbing overhead tanks. This ladder is been modified to meet the user’s needs.
