Using the effective rigidity of metal materials and the elastic compression ratio of sealing materials, and taking full advantage of the length of the socket, the connection method of radial crimping with clamps (or dies, jaws) on both sides of the U-shaped groove of the socket of pipe fittings is called double crimping.
Double clamping principle
Due to the full use of the effective rigidity of metal materials, the two ends of the pipe and pipe fittings are crimped with calipers at the joint to realize the face-fixing, compression into two hexagonal shapes, and comprehensive anti-lock, thus greatly improving its anti-pulling ability and anti-rotation energy. The double-clamp type pipeline adopts the advanced compression ratio principle of the O-ring seal. After the O-ring in the U-shaped groove is compressed, it gives play to its long-term elasticity, thus achieving the purpose of permanent sealing. In addition, the double-clamp pressure can effectively prevent the risk of water leakage when the pipe is not inserted to the bottom during construction due to the advantages of the socket.
Advantages of double-clamp connection
1. Uplift resistance principle: small mouth and large inside, with uplift resistance ＞ 3.0 MPa;
Anti-rotation principle: press into hexagonal shape to prevent water leakage during rotation;
Leakage sealing principle: implement the leakage sealing of the national standard O-ring seal, not the leakage sealing;
Reliable: good seismic resistance, excellent pull-out performance, suitable for concealment, maintenance-free and long life;
Economical: Mainly using cold rolled coil material, with good density and low price.
2. Simple and fast installation: simple installation without maintenance; The installation of single pipe fittings is calculated in seconds, which is convenient and fast.
3. Avoid human factors: the installation quality is controlled by equipment to avoid the influence of human emotions, and there is no need for high-tech installation workers.
4. The installation equipment is light, does not require a lot of manpower, and saves resources.
5. The operating radius is small, and no large operating environment is required.
6. It Suitable for special environment: installation in special fields such as pipe well, ceiling, trench, אאז"ו ו.
7. High connection strength, good anti-seismic performance, excellent pull-out performance, suitable for concealment, enhanced anti-rotation principle, preventing rotation leakage in use, maintenance-free and long service life.
8. The safety and reliability of the socket are enhanced, and the installation is simple without maintenance.
9. Semi-flexibility: meet a little bending and expansion.
10. The anti-mechanical external force damage, anti-twist and anti-pulling performance of the double-clamp connection is more excellent and reasonable
11. And Compared with traditional products, the double-clamp water supply pipeline system is healthier, more advanced, more economical, more durable and more robust, and has five water-tight characteristics, such as “bending 30 degrees of joint looseness and no leakage”, “strong vibration and no leakage”, “flattening 70-80% of water leakage”, “rotating 360 degrees of water leakage”, and “pulling displacement and no leakage at the connection to a certain extent”, It is one of the safest and most reliable thin-walled stainless steel pipeline systems in China
The inner wall of the stainless steel water pipe clamping pipe fitting/Press fittings is smooth and bright, which is used for water supply. The water quality is pure and pollution-free. It is a high-quality water supply material for modern household building materials.
The specification of stainless steel water pipe clamp pipe fittings/Press fittings can usually be divided into four parts, one of which is 45 ° equal elbow (type A/B), 90 ° equal elbow (type A/B), equal straight, equal tee, equal cross, adjustable straight, clamp flange and pipe cap of DN15~DN100.
The second part is DN15 × 1/2 “to DN50 × 2 “specification 90 ° internal tooth elbow, internal tooth straight, external tooth straight, internal tooth tee, nut moving adapter, external tooth tee; Three parts are DN20 × 15 to DN100 × 80 specification reducing straight, reducing small and medium tee, reducing cross; The four parts are DN15 to DN25 right-angle internal tooth elbow and double-clamp bridge bend. If you need, you can consult online customer service for details of the stainless steel pipe manufacturer.
1. Safety design of sealing
The pipe and pipe fittings are connected by double compression, and the double sealing of rubber sealing ring and special anaerobic sealing agent is added to achieve 100% sealing effect of the interface, which is safer
2. Corrosion resistance and longer service life
Stainless steel is a thin protective film (purification film) formed on the steel surface by adding about 12-20% chromium and oxygen to the iron matrix, which prevents corrosion, so it has better corrosivity than ordinary steel.
3. Safe and convenient installation
The thin-walled stainless steel pipe is inserted into the clamping type pipe fittings coated with professional anaerobic sealant, and the special clamping tool is used for clamping, and the connection operation can be completed by closing the jaws instantly.
4. Low labor intensity
There is no need for complicated threading operation in threaded connection, nor for effect treatment in welding. As long as you know the construction essentials, you can operate and ensure the installation quality.
5. Do not use ignition source
The fire source is not applicable to the construction site, which ensures the safety of the construction site.
6. Lightweight piping
Thin-walled stainless steel pipe has 1/3 of the thickness of international galvanizing and has better strength. Because its strength is higher than that of other pipes and its flow rate is large, its lightweight advantage for high-rise building piping is particularly prominent.
Q: When will you arrange the production? A:We usually arrange the production immediately after receiving your payment if we have the item in stock. Otherwise, please confirm with us for lead time.
Q:How is press fitting works？
A:Stainless steel water pipe press pipe fitting is to use the rigidity of the steel pipe, through the use of special tools for crimping the stainless steel water pipe, to extrude and deform the pipe joint, thus increasing the friction between the pipe and the pipe fitting, and realizing the holding and sealing.
