What are the models of stainless steel soft joints, and what are the performance characteristics of

The models of stainless steel soft joints include ball joints, inner and outer nuts, claw type, open type, plug-in type, KXT type, etc., mainly KXT type, which mainly has the characteristics of high temperature resistance and high pressure resistance.

Stainless steel soft joints mainly use the unique properties of rubber, such as high elasticity, high air tightness, medium resistance and radiation resistance, the use of high strength, strong cold and hot stability of polyester cord obliquely crossed with its compound, by high pressure, high temperature molded cross-linking, high internal density, can withstand higher pressure, excellent elastic deformation effect, product structure design end arc high, long curve, with a large number of displacement functions, especially used in complex geological conditions, In places where the settlement is large and the cold and heat changes are frequent in pipeline operation, which is easy to cause pipeline damage, the elastic sliding displacement of rubber and the heat transfer and escape function of deformation mechanical force are used to effectively eliminate the displacement physical damage of pumps, valves and pipelines themselves. When the product is connected with the pipe flange, the bolt screw should extend to one end of the pipe flange to prevent the thread from crushing or puncturing the arch part of the rubber joint when it is compressed and expanded, and the bolts at each end must be compressed and tightened symmetrically to make all bolts tighter consistently.

When stainless steel soft joints are used in high-rise buildings, the pipeline must have a fixed bracket, otherwise the product should be installed with an anti-pull bracket. The force of the fixed support or bracket must be greater than the axial force, otherwise the anti-pull bracket device should also be installed.

Corrugated metal hose manufacturer: Hebei Rongsheng pipeline equipment****.

Stainless steel soft joint If the middle part is rubber The flange at both ends is stainless steel, then this is called stainless steel shock absorber throat, which is mostly used in chemical plants, paper mills or other corrosive places in the external environment, if the middle part is metal stainless steel corrugation, then he is called a metal hose, Gongyi City Xicun Yuxin Pipe Fittings Factory produces soft joints all year round.

1: Grade 316Ti stainless steel.

Two: chemical composition.

c：≤ si≤ mn≤ p≤ s≤ ni crmo ti≥5*c%~

Three: the scope of application, the field of application:

316L stainless steel is added with MO, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and can be used under harsh conditions; Excellent work hardening (non-magnetic). Excellent strength at high temperatures. 316L stainless steel is an austenitic stainless steel and cannot be strengthened by heat treatment.

It has good strength, plasticity, toughness and cold formability, as well as good low-temperature properties. Due to the addition of 2% MO on the basis of Cr18Ni8, the steel is endowed with good resistance to reducing medium and pitting resistance. It has suitable corrosion resistance in various organic acids, inorganic acids, alkalis, salts and seawater.

In reducing acidic media, its corrosion resistance is much better than that of 304

Four: Overview. The corrosion resistance of stainless steel is better than that of 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper.

And 316 stainless steel is also resistant to the erosion of the ocean and the aggressive industrial atmosphere. In intermittent use below 1600 degrees and continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is better not to act continuously on 316 stainless steel, but when 316 stainless steel is used continuously outside of this temperature range, the stainless steel has good heat resistance.

316L stainless steel has better resistance to carbide precipitation than 316 stainless steel, and can be used in the above temperature range. Annealing is carried out in the temperature range of 1850-2050 degrees, then annealed rapidly, and then cooled rapidly after rolling. It has high temperature resistance, easy processing, and high strength.

316L stainless steel, no post-weld annealing is required.

There are many models, but the model you want is mainly to see if it is consistent.

As far as is known, the common stainless steel quick couplings are generally only suitable for pipes and equipment with low pressure, and there is no nominal value. As a rule of thumb, it will not be able to withstand a maximum pressure of more than 1 MPaSo what are the models of commonly used stainless steel quick connectors, let's take a look:

The quick couplings are divided into 8 types: A-TYPE, B-TYPE, C-D, E-type, F-type, DC type, DP type, including 4 male connectors of A-TYPE, E-TYPE, F-TYPE, DP type and 4 female connectors of B-TYPE, C-type, D-type and DC type.

Manufacturing materials, aluminum alloys and other conventional materials. Other materials can also be processed in batches.

DN:DN15-DN150mm

Nominal pressure: 16-64kg

Applicable temperature: -20 150

Applicable medium: water, oil, gas and some corrosive liquids.

Scope of application: industrial, chemical, liquefied petroleum gas, vehicle and ship manufacturing equipment, etc.

Connection: threaded, welded, flanged, quick connect, wrench type, etc.

Quick couplings are generally packaged as a complete set or can be purchased individually as required.

Type A: One is the joint stuck in the female connector, and the other is the connection wire mouth of the internal thread;

Type B: On one side is a groove with two male puller plugs, and on the other side is a wire mouth with a male thread connection;

Type C: One is a groove with two male puller heads, and a slub-shaped hose connection on one side;

Type D: On one side is a groove with two male puller plugs, and on the other side is a wire mouth with an internal thread connection;

Type E: Fittings stuck in the female connector on one side and hose fittings with a slub on the other;

F-type: One is a fitting that is stuck in the female connector, and one side is a wire mouth with a male threaded connection'

DC type: It is a round plug with two pulling ears that can be snapped into the male head;

DP type: It is a round plug, also called a quick-release plug.

How to use stainless steel quick connectors: Model B, C, D, DC can be assembled with any one of models A, E, F, DP to form a set of quick coupling products, and vice versa. Therefore, you can choose products according to your specific needs.

The above is some sharing about the stainless steel quick coupling model,

1. According to the size and dislocation of the joints at both ends of the required connection.

2. It should be sealed and tightened.

3. When pre-bending the corrugated soft joint, the looper nut should be placed at both ends of the corrugated soft joint to avoid the nut being stuck when the bellows is bent.

4. Pay attention to the installation process, do not collide with hard objects, do not damage the sealing surface.
