Perform flushing, cleaning of equipment

Why does removing process contaminants is carried out?

• in order to protect equipment from corrosion

• in order to reduce the risk of critical formation of deposits

• in case of putting the equipment into operation

• in case of safe working conditions

Who is responsible for the cleaning of the process equipment ?

• The engineering personnel in charge

• Electricians

• Trained specialists and using the special chemical agents

• Pipe mechanics

What is the forth step of cleaning?

• Image printing

• Developing

• Stripping

• Etching

What is etchant?

• a mixture of oxygen molecules

• a mixture of hydrocarbons

• a mixture of halogens

• a mixture of acids or alkalis

By what the removing of chemical deposits and carbon deposits, also the removing of surface layer before the protective coating is carried?

• Cutting

• Pickling

• Scaling

• Ripping

Find correct mandatory conditions during the preparation.

I) Work is carried out on the shutdown units;

II) To organize additional ventilation at the place of work;

• Both are correct

• Only I

• Only II

• Both are incorrect

Choose the correct statement regarding the chemical decreasing.

• products of technological processing must be removed

• it is necessary to provide conditions for dismantling of units and parts for further

  processing in specialized conditions of our company

• it is necessary to free up space around the place of work performance

• acid or alkaline solutions are used as degreasing agents

2) Where does the grease, scale and carbon may form?

• Containers, pump

• Gas and fire burners

• Heater, reactor

• Pipe, condenser

What is necessary to do before putting the equipment into operation?

• to detect microscopic defects on parts in the production process

• conclude a contract with an organization engaged in maintenance and flushing of boilers from scale

• make sure that the equipment needed to get the job done is complete

• carry out a diagnostic examination to determine the degree of wear

Etching is used..

• to carry out a diagnostic examination to determine the degree of wear

• to free up space around the place of work performance

• to provide conditions for dismantling of units and parts for further processing in specialized conditions of our company

• to bring water to the place of work performance and organize waste water removal
