The letter symbol representation method of galvanized steel pipe. Galvanized is also called "metal", so it is also called "metal wire pipe". There are two kinds of distinctions: thick-walled and thin-walled. Electrical and control circuit protection. Line pipe can be divided into two types, one is jdg line pipe and kbg line pipe. Many people do not know what the letter symbols on the steel pipe mean when purchasing or using galvanized line pipes. The following editor will explain to you.
There are several types of threading pipes, plastic type, galvanized metal type, and various types of threading pipes have their different symbols and letters to indicate abbreviations. Electrical construction drawings will also be marked with letter symbols. This is the wire pipe. Symbols are abbreviated, so make sure you know what letter is what tube.
Representation and classification of alphabetic symbols of galvanized pipes:
Welded steel pipe (sc), tightened galvanized thin-walled electric wire pipe (JDG), crimped galvanized thin-walled electric wire pipe (KBG), metal hose (CP), electric wire pipe/thin steel pipe (tc), galvanized steel pipe ( RC), wire tube (MT).
Pvc plastic threading pipe symbol letter representation and classification:
Rigid plastic pipe (pc), semi-rigid plastic pipe (FPC)
Laying methods of common line letter codes in electrical design and construction drawings:
(When installing the electrical conduit, it must be constructed in accordance with the laying method of the design drawings)
SR: Lay along the steel trunking
BE: Lay along or across the roof truss
CLE: laying along or across columns
WE: laying along the wall
CE: laying along the ceiling surface or ceiling surface
ACE: laying in the ceiling where people can enter
BC: Concealed laying in the beam
CLC: Concealed in the column
WC: Concealed laying in the wall
CC: Concealed laying in the ceiling
ACC: Concealed installation in the inaccessible ceiling
FC: Concealed laying in the ground
SCE: For laying in the ceiling, it is necessary to wear metal pipes
DB-direct burial
TC-cable trench
BC - Concealed in the beam

The content of the letter symbol representation method of galvanized steel pipe is introduced here today. There are many kinds of symbol representation of steel pipe. If you don’t touch it often, you only need to remember a few keywords. Regarding the spit of the line pipe, it is only marked SC20 strictly. Said to be welded steel pipe, galvanized SC20 is the real galvanized steel pipe. We can also pay attention when purchasing.
