7. FC: laying on the floor or under the ground

2.

The differences between sc20-cc and sc20-ccwc are as follows: different concealed laying methods, different joints and different connection methods

Different dark compression methods

< P >

1. Wire tube sc20 CC: wire tube sc20 CC can only be dark on the wall, not on the roof or roof

2. Wire tube sc20 ccwc: wire tube sc20 ccwc can be used secretly on the roof or roof or wall

There is no rubber seal on sc20 CC joint, which is not suitable for thermal expansion and cold contraction, and can not prevent sand from entering

Three, the connection way is different

1. Sc20 CC: sc20 CC is generally connected by wire welding or sleeve fusion welding

2. Sc20 ccwc line pipe connection: sc20 ccwc line pipe connection can adopt thread connection, fastening connection and buckle connection, and sleeve can not adopt fusion welding connection

3.

The analysis is as follows:

1. SC is laid through steel pipe, that is, steel pipe or galvanized steel pipe is used when threading

2. CC is laid along the ceiling, that is, cables are laid on the ceiling or suspended ceiling

Jewelry Collection https://rj.mbd..com/urj7d7j

first place: Harry Winston

a world-renowned super jewelry brand for more than 100 years. The exquisite craftsmanship and careful consideration in diamond cutting can always increase the value of diamonds by several times

birthplace: the United States

founding year: 1932

founder: Harry Winston

brand story: in 1893, the father of Japanese pearls, Yukichi KIMOTO cultivated the first perfect pearl, and then founded Mikimoto“ Only by persisting in the proction of the highest quality pearl, can there be hope for Japanese pearl cultivation! " This is the vision of Mikimoto and one of the reasons why he won the reputation of "the Pearl King". In 1893, the first cultured pearl was "born" in Japan. Although the semi-circular pearl is not perfect in shape, it is the first successful step of artificial breeding. Twelve years later, the perfect spherical pearl finally appeared. The inventor behind this invention, which even Edison, the king of invention, admitted that he could not make in the laboratory, is Yukio yukimoto, who has the title of "father of cultured pearls"

proct features: the core of the whole brand of yumuben is pearl. It can be said that the quality of Pearl directly determines the value of the brand. Only 10% of Mikimoto's pearls have passed the strict selection criteria. In addition to being recognized as the most precious dowry left by the mother to her daughter in Japan, Mikimoto also won the recognition of the Japanese royal family in 1924 and became a jewelry store for the royal family

celebrity anecdote: Mikimoto has become the official jewelry sponsor of Miss Universe since 2002, and the crown designed for Mikimoto has also been made on Pearl Island. Like the vivid lines of the Phoenix, 800 round cut diamonds with a total weight of about 18 carats, together with 120 Nanyang pearls and Japanese beads, are luxuriously inlaid to add beauty to the new global queen every year. Another diamond pin, which is also inspired by the Phoenix, shows a sense of hierarchy like a feather, and also metaphors the rebirth and continuation of life, just like a phoenix bathing in fire
