Galvanized wire should be how to maintain

In our life a lot of things need maintenance, such as new bought a pair of shoes, will often give shoes clean oil, or after a long time left the ashes, or whatever don't ask, don't throw in one side, and after through the leather shoes will shorten the life of a. Cold wire drawing also need maintenance, so as to guarantee the quality of construction.

Cold wire drawing with the same qualities, and many other iron objects, such as common a kitchen knife in the air will rust, later will also touched water rust, long time not to use a kitchen knife will become a pair of rust corrosion, cold wire drawing, too, if you accidentally touch the water, it will produce rust, rusty iron wire is known to all, if you only have a little rust then it won't keep using, if rust is badly is very serious, so its quality problems, in the process of use will appear a lot of problems. So cold wire drawing need good maintenance and maintenance.

Cold piping insulation

1 category

The original scale fold used to make up in the air conditioning system cooling pipe insulation engineering.

2 the construction preparation

2.1 information and secondary equipment:

2.1.1 insulation materials should fold the comfortable vision and have the six-year-long boycott factory pass the true or inspection speech.

2.1.2 insulation materials with polyurethane rigid foam (hard) hard (hard), polystyrene foam plastic shell plastic shell, rock wool pipe shell, etc. The above material should be small coefficient of thermal conductivity, have certain strength can suffer from the medial side of the water wet or gas in the war, does not contain corrosive substance, non-combustible or won't burn, convenient for construction.

Galvanized iron wire equipment 012 cold piping insulation technology, 2.1.3 insulation information is stored, shipped, implicit wins keep in moist and machine reputation should be no injury.

2.1.4 hand electric drill, inadvertently, wire cloth scissors, pliers, screwdriver, putty knife, small oil brush, float, barrels, hook, etc.

2.2 job premise:

2.2.1 flammable materials necessary for its resistance to gas turbine can check verification, pass the round after can use.

2.2.2 pipe insulation construction is necessary system pressure leak detection test pass, anticorrosion treatment of stern into the check in advance.

2.2.3 garden should be clean and dirty turbidity clean, has good lighting equipment. In winter and the rain period construction should have frost sleet prevention measures.

2.2.4 the steam-water pipes more than not liner loss or packing should supplement. Instrument to accept parts have been installed.

2.2.5 should be the builder of the writing craft, quality, and suppress Ann clarificaiton. Heat preservation should be carried out to the check before inspection.
