Explosion-proof union structure features and thread specification

Explosion-proof joints are used in the explosion-proof electrical distribution system as a conversion connection. Its structural features are: high quality carbon steel, stainless steel or brass, high strength; connection thread specifications can be based on user requirements, such as G thread, NPT thread, M metric thread and other non-standard threads; explosion-proof joints in a variety of structural forms, such as:

A: Conversion connector (F≥M)

M: External thread P: Plug R: Reducing sleeve (F<M)

E: Internal thread bend LN: Lock mother F: Internal thread straight T: Thread connection of three-way explosion-proof union of internal thread can use metric thread M, pipe thread G, NPT thread and PG thread according to user requirements. Reducing diameters should be marked in detail at each end of the thread. The middle is connected with “/”. The internal and external threads of the adapter and the reducing sleeve should be marked separately. The external thread is filled with “M” and the internal thread is filled with “F”. Order: Max. threaded end / maximum end opposite end / branch end.

Explosion-proof joint manufacturing materials are: C: carbon steel, galvanized surface or zinc yellow B: brass or brass nickel plating

Exterior Wall Rock Wool Insulation Board

Rock wool board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material through high temperature melting processing. It was successfully tested in June, 1981. Rock wool board is a new type of thermal insulation, flame-proof and sound-absorbing material.

The artificial inorganic fiber made of rock wool board by high temperature melting process has the characteristics of light weight, small thermal conductivity, heat absorption and incombustibility. The initial development is a common type of application in construction, which is mostly used in industrial buildings. It should meet the requirements of "Application Types and Basic Requirements of Building Thermal Insulation Materials". Rock wool is a kind of external insulation material. When the market share of 90% of the organic thermal insulation materials is stagnant, rock wool, as an inorganic thermal insulation material for exterior wall, has ushered in an unprecedented market opportunity.
