Water pipe purchase knowledge
1. PPR pipes, steel-plastic pipes and copper pipes are generally used for water pipes for home decoration. The price of steel-plastic pipes is relatively high, while the price of PPR pipes is higher than that of steel-plastic pipes. The price of copper pipes is the most expensive, and the price is equivalent to PPR pipe. About 4 times.
2, home decoration laying pipes should try to avoid laying from the ground, preferably from the top or wall, the pipe usage may increase slightly, but it is conducive to future pipeline maintenance.
3, the wall thickness of the hot and cold water pipe is not the same, the cold water pipe can not be used as a hot water pipe, the easy way to distinguish the hot and cold water pipe is a red line mark on the hot water pipe.
4, the standard length of PPR pipe is four meters each. When buying, please ask the price of each pipe or the price of pipe per meter. After the pipe is sent, remember to check whether the length of the pipe meets the requirements.
5, the water pipe for home decoration should pay attention to the pipe diameter and wall thickness, the general pipe should use 6 points, the pipe can be used to 4 points, in order to ensure the water consumption, the pipe can also use 6 points.
6, when the home decoration purchase pipe, pay attention to whether the inner diameter of the pipe is symmetrical, the uneven diameter of the pipe diameter will affect the docking of the two interfaces.
7. The “Construction and Decoration Engineering Quality Standard†of the Building Decoration Industry Association has such a regulation on the time and pressure of the pressure test: the newly installed water supply pipeline must be subjected to the pressure test according to the relevant regulations. Metal and composite pipe test pressure 0.6MPa, voltage regulation for 10 minutes, pipe pressure drop should be no more than 0.02MPa, no leakage; plastic pipe test pressure 0.8MPa, voltage regulation for 20 minutes, pipe pressure drop should be no more than 0.05MPa, no leakage.
Industrial Grade Salt
Sea Salt has hundreds of industrial applications. It is very
widely used in chemical
industries, for example, the Chlor-Alkali
industry, which uses chiefly
salt to manufacture chlorine
and caustic soda. Chlorine and caustic
soda are used further in the manufacture of paper. It is also used as a water softener. Soft water can more economically use soap and detergent, and is therefore ideal for cleansing purposes. Rubber manufacturers use salt to
separate rubber from latex. It is used in the metal industry to remove impurities from metal. We produce A
and B Grade Sea Salts for such industrial uses.
Another major use of salt is de-icing, removing ice from
a surface. Although rock salt is the more common type of salt for this purpose,
sea salt is also perfectly suited to perform the task. This works by spreading
diluted salt over the frozen surface. Since salt water has a lower freezing point than pure
water, ice melts away as
soon as it absorbs salt. We produce a C Grade Sea Salt for de-icing purposes.
