Introduction to edit
Product name: explosion-proof union
Product name: explosion-proof union
Product model: BHJ
The explosion-proof marks: Exd II
Protection grade: IP55
Scope of application editor
For the dangerous sites 1, 2.
Type IIA, IIB, IIC explosive gas environment.
Combustible dust environment 20, 21, 22.
Temperature classes T1, T6 environment.
Suitable scope of anti-explosion union group meaning:
Danger zone division 1.1 explosive gas environment

0 area: present continuously or explosive gas mixture of environment for a long time.
1 area: the possible explosive gas mixture in the normal operation of the environment.
2 area: during normal operation is not possible environment of explosive gas mixture or even the appearance is only short existence environment of explosive gas mixture.
0 area generally exist only in the sealed container, storage tank internal gas such as space, in the process of real design 1 area there are very few, most of the time belongs to 2 zone.
1.2 the explosion-proof electrical equipment is divided into two categories:
Ⅰ electrical equipments used in coal mine
Type Ⅱ except mine using electrical equipment
1.3 Ⅱ kind of electrical equipment, according to its biggest test is suitable for explosive gas mixture security clearance or minimum ignition current ratio, divided into Ⅱ A, Ⅱ B, Ⅱ C three categories;And according to its maximum surface temperature into T1 - T6 six groups.
1.4 with explosive gas mixture by grouping, ignition temperature are shown in table 1.
1.5 with explosive gas mixture, according to its maximum experimental safe gap (MESG) or minimum ignition current ratio (MICR) classification, as shown in table 2.
Table 1

Q:What are the categories of ductile iron pipe fittings?
The heat pipe trench is in rotational groove tube internal high temperature composite cold water general PE, cohesive force is very strong and do the destructive test will be found with a knife, the pipe made by hot plastic process, lined with PE layer inside the hard to cut down. The injection pipe is a kind of composite pipe formed by injection of PP into the inner part of the groove pipe.
Q:How can ductile iron pipes be connected to steel tubes?
Disk or disk plug connection, it is best to use flange connection.
Q:How can the ductile iron pipe be connected to the PE pipe?
Through the conversion of fittings, because different PE pipes and ductile pipe diameter pipe, so name is needed for the step coupling, called Chinese stepped rod joints
Q:Connecting process of ductile iron pipe spigot and socket rubber ring
Rubber seal ring is formed by one or several parts of the cover, fixed in a ring or a washer bearing and another ring or gasket contact or the formation of the labyrinth of narrow gap, to prevent leakage of lubricating oil and foreign matter.
Q:How many kinds of elbow of ductile iron pipe?
You can measure the big money to camber, can call to the manufacturers to build. Seems to have 12.5 and 22.5 degrees, in the first two months we used 22.5 degrees elbow, the drawback is not good pull
Q:How much is the installation of a two degree elbow for ductile iron pipe fittings at 11.25 degrees?
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. In the ferrite and pearlite matrix on the distribution of a certain number of spheroidal graphite, according to the nominal diameter and the elongation of different microstructure of ferrite and pearlite in different proportions of small caliber pearlite percentage is generally not more than 20%, large diameter of the general control in about 25%. Minimum tensile strength: 420/Mpa, minimum yield strength 300/Mpa, minimum elongation 7%.
Q:Is the ductile iron pipe metal pipe?
Ductile iron is an alloy of ironDuctile iron pipes are alloy tubes of iron
Q:How to improve the quality of nodular cast iron pipe fittings
When the molten iron temperature is too low and the inner wall temperature of the tube is low, heavy skin defects will occur. When the molten iron temperature is high and the molten iron gas increases, porosity defects can be generated. In the medium frequency furnace, the hot metal should be provided according to the process specification, and the temperature of the inlet and outlet and the cooling rate can be controlled reasonably in the process of production.
Q:How to inspect ductile iron pipe fittings?
While the proportion of the so-called K8 class cement pipe and some manufacturers terrifying 3/4 or 3/5, as the water supply pipe 3/5 or no personally think that two of the proportion of the tube is not the problem, the most intuitive way of judging the quality of ductile pipe is cement and iron thickness ratio of thicker tube wall thickness of cement the better the quality, some manufacturers of production pipe, thick wall pipe head cast iron part looks to be thick, but there is also a thin iron pipe, so the judge quality to cut inside, personally think that the highest price of the manufacturer is Jinan steel, Jinan Iron and steel because the pipe quality can reach the national standard K9, the price is also below new, Saint Gobain and other major brands, as the water supply pipe K8 is no problem, but the price and quality for the construction of what importance Stronger.
Q:Comparison of C and K grades of ductile iron pipes
Using more than 18 cast iron, after adding the spheroidizing agent, the centrifugal casting of ductile iron machine caused by high-speed centrifugal tube, known as "ductile iron pipe."".
