Detailed Product Description

Welding neck forged flange

ASME B16.5 STANDARD A105 CARBON STEEL

Q:What is the difference between a threaded connection and a flanged safety valve?: There is no difference in useJust the connection is not the sameThread connection is mainly used for small caliber valve, 50mm or soFlanges are generally used in large and medium-sized safety valves

Q:I don't know what kind of classification these two belong to: The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Fittings pipe (flanged) means a pipe with flanges (flanges or plates). It can be formed by casting and (figure not available), may also be threaded or welded together.Flange structure: strip welding, socket welding, threaded connection, loose sleeve, butt welding and flange capThe orchid screw is a special kind of screw. Unlike regular screws, its prominent link weight bearing function. Mainly used in assembly lines, large construction sites, large factories, lifting plants, ship transport, bridge construction, high-rise buildings and so on.

Q:The difference between flange and flange B: 1, the difference is that the pressure range, temperature range, medium toxicity range, optional gaskets are also different;2, welded flange, welded flange flange ring only, usually made of steel, forging and rolling can be used when necessary. In connection, it is directly welded with the cylinder or head. The whole flange ring and the cylinder head or connection, small stiffness and joint strength of welded flange, it applies only to a relatively low temperature and pressure. In the current industry, welded flange has 4 pressure levels (PN0.25, 0.6, 1, 1.6MPa), the scope of the nominal diameter is smaller (DN3002000mm), the working temperature range of 300 from-20 DEG C.Hepatitis B: the difference between flange flange to flange welded flange is the main ring with a short. Flange rings are usually made of steel plates or made of forgings. In connection with the short tube or head butt welding, the flange type B good integrity, its strength and stiffness than the welded flange. In the current industry, the pressure range of B flange is large, there are a total of 6 pressure levels (PN0.25, 0.6, 1, 1.6, 2.5, 4.0MPa). The nominal diameter scope is: DN3003000mm, suitable temperature: from-20 DEG C - 350.

Q:What is the difference between the coplanar flange of the transmitter and the traditional flange? What are the advantages and disadvantages? Thank you: Say something Ross doesn't like to hear, and their transmitters are designed with coplanar flanges to shield other home products. Coplanar flanges have advantages, but they also have disadvantages. These are not easy for me to say here. I can ask some users. In addition, Ross Monte has a three valve group is used coplanar flange, you buy this transmitter, you may choose the three valve group, you change later, there is no choice. It's just a business problem, not a technical one.

Q:The system, main equipment, piping and so on should adopt the fixed type heat preservation structure, the flange, the valve and so on should adopt the removable heat preservation structure. What is called the fixed heat preservation structure?,: The removable insulation structure means the insulation used in the place where it is often disassembled and maintained, and can be disassembled and overhauled as a whole. After the overhaul, the whole insulation layer can be conveniently and directly mounted. Fixed type thermal insulation structure is insulation pipes, some regular maintenance equipment, the thermal insulation is fixed on the equipment, only the equipment overhaul, all the damage to the insulating layer to open, the repeated use of the insulation layer can not.

Q:The choice of flanges for the European system and the American system: The two standard flanges are HG20592 and HG20615, and domestic flanges are generally used in the European system. If exports are American system flanges

Q:Where is the flange used in the pump?: Flanges are used on pipes and valves that are connected to the pump. Generally, each pump inlet and outlet at least three flange and a two valve valve.

Q:What is flange connection pile?: Classification of pilesWith the development of engineering technology, new steel pile and reinforced concrete pile are more and more widely used in engineering construction. Different pile types have different characteristics.Classification according to force condition:Friction piles - most of the load is carried by the friction of the soil around the pile, while the pile at the end of the pile can be neglectedPileEnd bearing friction pile -- the pile whose load is mainly borne by the friction force of the pile bodyEnd bearing piles - most of the load is carried by the supporting force of the pile tip, while the resistance at the side of the pile is negligibleFriction end bearing pile -- the pile whose load is mainly loaded by the end of pileClassification by construction method:Mechanical hole pileBored pileImmersed tube cast-in-place pileReinforced concrete pilePile foundation, precast pile, prestressed concrete pileSteel pileCement soil mixing pileMixing pileOther chemical material mixing pilesAccording to the overall size of the pile classificationLong pilePileShort pileMiddle long stakeVariable cross-section pileAccording to the method of pile driving, prefabricated piles can be divided into driven piles, pressed piles, vibrating sinking piles, rotary piles and so on.

Q:Should the flange of 1.0MPa be expressed as PN1.0 or PN10?: After mixing, the trouble is great, and the pressure of 10KG is 100KG.

Q:Is the flange connection necessary for the connection of the filter DN150?: How much is your pipeline pressure, if 10 kg of pressure can be threaded connection, flange connection must be high pressure; general or flange connection, easy handling, easy to leak, firm connection etc.; pipeline DN25 our company original equipment of 30 kg with flange connection.
