Shotblasting hoses

A shotblasting hose is a hose that is used to transport shot and other high-friction materials, such as glass or sand. It is usually formed from rubber, but plastic versions also occur. However, regardless of the type, shotblasting hose is characterised by a very high resistance to abrasion and external deformation during operation in harsh environments.

 Shotblasting hose is available in a variety of diameters and lengths, so you can easily adapt them to your specific installation. Using them, you will effectively transfer the abrasive from the shotblasting machine to the nozzle and then onto the surface to be cleaned. You will also do it safely, as shotblasting hoses are characterised by anti-static and insulating properties.

Shotblasting hoses

How is a shotblasting hose constructed?

Shotblasting hose is constructed from several layers in order to withstand the impact of the abrasive material,:

  • inner layer — this is resistant to the abrasion and high temperatures that result from the friction of the blasting material against the walls of the hose, and is also characterised by its smoothness, which facilitates the flow of material and extends the life of the hose;
  • reinforcement — this is in the form of a braid (of statically neutral material) and is responsible for the resistance of the hose to working pressure;
  • outer layer — is usually formed from anti-static rubber, which is resistant to ageing and mechanical damage from the use of the hose.

Some shotblasting hoses also have an integrated copper wire which, when earthed, dissipates electrical charges and increases safety when working with the shotblasting machine.

What types of shotblasting hose are there?

The most popular types of shotblasting hoses are ceramic-lined hoses, polyurethane-lined hoses, and rubber hoses.

  • ceramic-lined hoses — as the name suggests, these are hoses that have ceramic beads embedded in the inner layer (so they are characterised by significantly greater strength and longevity); 
  • polyurethane-lined hoses — thanks to the PU-lined inner wall, the hose is characterised by a very high degree of smoothness and low coefficient of friction, which has a positive effect on its service life 
  • rubber hoses — these are standard shotblasting hoses made of rubber (usually NR rubber or SBR rubber), which is characterised by increased abrasion resistance.

Depending on the type, hoses may differ in price and some parameters.

How to choose the right shotblasting hose?

When choosing a shotblasting hose, pay attention to its maximum operating pressure, temperature range, abrasion resistance and the inner diameter.:

  • maximum operating pressure — never exceed the permissible pressure values for the hose in use, as this may result in a dangerous failure;
  • operating temperature range — remember that in adverse conditions, the properties of the hose will deteriorate, accelerating wear and increasing the risk of damage; 
  • abrasion resistance — this is determined by ISO 4649 or the older DIN 53516 (in this case, the lower the value, the better);
  • nominal inner diameter — match this to the installation (also consider that a wider hose reduces frictional losses);

How to care for a shotblasting hose?

To care for a shotblasting hose remember about the following:

  • the internal diameter of the hose should be 3-4 times the capacity of the nozzle;
  • always cut shotblasting hoses at a right angle;
  • try to avoid sharp bends when using the shotblasting hose; 
  • after use, remove abrasive residue from the inside of the shotblasting hose with a jet of compressed air; 
  • store the shotblasting hose in a dry and clean place where it will not come into contact with oils, chemicals, and paints; 
  • avoid prolonged hanging of shotblasting hoses on hooks, hangers, etc.

FAQ

How often should I change my shotblasting hose?

arrow-up

Many experts recommend replacing a shotblasting hose after a year or so of operation. However, consider that if the hose shows signs of wear sooner, you should replace it as soon as you notice them. By doing so, you will ensure the safety of your employees and increase the efficiency of your shotblasting machine. It is also worth noting that by taking care of the hose and using it as intended, you will extend its life.

How can you recognise when a shotblasting hose is worn out?

arrow-up

You can most easily recognise wear on a shotblasting hose by external signs of wear, such as holes, cracks, tears or erosion of material on the hose wall. The second way is to squeeze the hose every 20 cm of length. If it is in good condition, it will not give up easily. If, on the other hand, you squeeze the hose without much problem, this means advanced erosion of the inner wall of the hose. In this situation, you should consider replacing it.

Can I join two or more shotblasting hoses together to increase the abrasive transfer range?

arrow-up

You should not connect two or more shotblasting hoses together, as the connection point will be a weak point in the installation. It will lead to a pressure drop and consequently a deterioration of the blasting performance.
