In life and production, the use of screws is very extensive, and the specifications and types of screws are numerous and can be used in various fields. And Faswell is going to introduce you to the ring screws today. The ring screws are made of warm-tempered fire and have been polished in a variety of processes to make the surface more resistant to corrosion. Its strength is 20 times that of ordinary screws. It is mostly used for locking steel wire, steel pipe, and various mechanical combinations. Then let's take a closer look at the eyebolts and see what exactly they have.
Strength standard for eyebolts
The eyebolt can withstand 2.5 times the high-intensity overload. It was subjected to 20,000 fatigue tests at 1.5 times the working load. The eyebolts are still in compliance with or exceed the requirements of ASME B30.26. Most of the eyebolts are made of alloy steel and then produced in accordance with the German RUD WBG type. Products can be sold all over the world, but need to pass the local G80 standard test. The pull-out force of the domestically produced eyebolts in China is higher than that of ordinary eyebolts. The test of the eyebolt screws shall be carried out by a professional and shall be referred to the instructions for use. When connecting with the spreader, the joint between the spreader and the eyebolt shall be kept freely rotatable.
Use of eyebolts
The ring screws have high strength and corrosion resistance, so they are widely used in ports, shipbuilding, petrochemical, mining, construction, automobile manufacturing, plastic machinery, industrial control, highways, large-scale transportation, marine rescue, marine engineering, airport construction. , bridges, aviation and other fields.
Ring screw specifications
There are many types of eyebolts, and the specifications currently on the market are as follows.
1.M8X1.25-6g, thread length: 12mm, working tension: 0.4T, product weight: 0.27KG/only
2.M10X1.25-6g, thread length: 19mm, working tension: 0.5T, product weight: 0.27KG/only
3.M12X1.75-6g, thread length: 19.1mm, working tension: 1.05T, product weight: 1.2KG/only

7.M22X2.5-6g, Thread length: 38.1mm, Working tension: 2.25T, Product weight: 2.21KG/only
8.M24X3.0-6g, thread length: 38.1mm, working tension: 4.2T, product weight: 2.21KG/only
9.M30X3.5-6g, Thread length: 50mm, Working tension: 5T, Product weight: 3.86KG/only
10.M33X4.0-6g, Thread length: 50mm, Working tension: 7T, Product weight: 3.86KG/only
After the above introduction, not only can we understand the standards and specifications of the eyebolts, but we also know that it is widely used. That's right, as a kind of screw with a very high strength, how can it be less in production and processing? The most gratifying thing is that the specifications are very large and can be used in different fields, even if the applicable specifications are not found. It can also be customized, and the processing method is still very convenient.
Heat Pipe Solar Collector is one type of Vacuum Tube Solar Collector.
The
selective coating on the inner cover of the Vacuum Tubes
converts solar energy and transfers heat to the heat pipes
by aluminum fins. The liquid in the heat pipe changes into vapor
which rises to the condenser. Then the heat passes through the heat
exchanger, the water inside of header pipe is being heated, and the vapor
becomes liquid, returning to the bottom of the heat pipe. This
transference of heat creates a continuous circulation as long as the heat
pipe Vacuum Tube collector is heated by sun.
Heat
is transferred by liquid to the header pipe and heat the water efficiently. In
addition, heat pipe vacuum tubes is highly freezing resistance, which ensures
higher efficiency in cold areas.
Heat pipe solar collectors can be used in both pressurized or non-pressurized circulation systems.
Evacuated heat pipe technology
1. Evacuated tubes based on the thermos flask principle and consisting of two concentric glass tubes and an evacuated gap to prevent heat loss.2. Highly selective absorber layer on the inner glass tubes (AI/ALN,) which enables an optimum energy yield.
3. Aluminum heat transfer plate to provide an optimum heat transfer medium system.
4. Copper heat pipes transfer the extracting heat effectively.
5. Rock wool insulation with an aluminum lamination in order to prevent heat loss in the manifold.
6. Compression ring fitting (Ø 22 mm) for flow and return which enable a safe and easy-to-install pipework connections.
7. The most common working fluid is water for ambient temperatures of - 30 °C to an operating temperature to 90 °C.
