What are the types of pipe fittings

Pipe fitting is a part that combine pipes into pipelines. Pipe fittings are used in water conservancy, irrigation and drainage fields. According to the connection method, it can be divided into four types: socket pipe fittings, threaded pipe fittings, flange pipe fittings and welded pipe fittings, which are usually made of the same material as the pipe. In addition to the classification according to the access method, there are also other classifications. Now let's look for the types of pipe fittings.


Specific classification of pipe fittings:

Pipe fittings include elbows (elbows), flanges, three-way pipes, four-way pipes (cross heads) and reducers (small and small heads). The elbow is used as the turning position of the pipe; the flange is used as a part to connect the pipe to the pipe and is connected to the pipe end; the three-way pipe is used as the location where the three pipes converge; the four-way pipe is used as the location where the four pipes converge; The reducer is used as the location where two pipes with different pipe diameters are connected. Pipe fittings can be divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc. according to manufacturing standards.


Basic definition:

Pipe fittings are a general term for the parts and components that play the role of access, control, change of direction, diversion, sealing, and support in the pipeline system.


Common categories:

There are many types of pipe fittings, which are classified according to use, access, material, and processing methods.

Classified by purpose:

1. The pipe fittings used for mutual connection of pipelines include: flanges, unions, pipe clamps, clamps, clamps, hose clamps, etc.

2. Fittings that change the direction of the pipeline: elbows, elbows.

3. Fittings for changing the diameter of the pipeline: reducing diameter (reducing pipe), reducing elbow, branch pipe stand, reinforcing pipe.

4. Increase the number of pipe fittings for pipeline branches: three links and four links.

5. Pipe fittings used for pipeline sealing: gaskets, raw material tapes, hemp, flange blind plates, pipe plugs, blind plates, heads, welding plugs.

6. Pipe fittings used for pipe fixing: snap ring, towing hook, lifting ring, bracket, bracket, pipe clamp, etc.

Microfabrication of biomedical lab-on-chip devices. A review/Biomeditsiiniliste kiiplaborite valmistamine.

1. INTRODUCTION Lab-on-chip technology focuses on the development of hybrid devices, which integrate fluidic and electronic components onto the same chip [1-5]. They are devoted primarily to liquid sample testing and handling. Such devices reduce laboratory processes in a manner competitive to bench-top instruments. Lab-on-chip technology emphasizes integration, chip programmability, increased sensitivity, minimal reagent consumption, sterilization and efficient sample detection and separation. Lab-on-chip functionality includes sample handling, mixing, filtering, analysis and monitoring. A typical lab-on-chip device contains microchannels, which allow liquid samples to flow inside the chip, but also integrates measuring, sensing and actuating components such as microvalves, microfluidic mixers, microelectrodes, thermal elements, or optical apparatuses. Some commercial lab-on-chip devices incorporate electronics that operate their apparatuses (Fig. 1). The lab-on-chip devices are c

Summer is in full swing in Oklahoma and the kids, grandkids, nieces, nephews and, well, just about everyone we know is in Lake Zumwalt to cool down. My wife has purchased enough pool toys to fill Lake Zumwalt, so I figured I would join the pool toy fray with WiFi Paddle Boat.WiFi Paddle Boat is a paddle boat controlled via wifi using rubber a smart phone, tablet or other touch enabled device. WiFi Paddle Boat creates a wifi access point (much like the small sport cameras) that you connect to via your wifi enabled device wifi settings. Then, using your wifi touch enabled device web browser, you simply navigate to the WiFi Paddle Boat web page and off you go! The controls for WiFi Paddle Boat are identical to those of my "Lady Buggy" and "Santa Sleigh" designs so it's easy for the grandkids to operate.A word of caution; I designed WiFi Paddle Boat to be "splash resistant" not "water proof", so if a rogue wave, grandchild, niece, nephew, et

Analysis of mechanical seal leakage Cause

In centrifugal pumps and reaction kettles, the seal between the rotating pump shaft and the stationary casing is simply referred to as a shaft sealing device. Currently, centrifugal pumps and reaction kettles are commonly used for packing and mechanical seals. Mechanical seals are widely used because of their advantages such as small leakage, long service life, low power loss, no need for frequent maintenance, and low environmental impact. The manufacture of mechanical seals is complicated and requires high precision. During operation, the inspection personnel are required to find problems in time and deal with them as soon as possible, so as to extend the service life of mechanical seals. Vibration, heat and smoke of mechanical seal 1. The end pressure is larger Treatment measures: (1) Adjust the position of the moving ring base to reduce the specific pressure of the end surface; (2) Replace the mechanical seal spring to reduce the end surface specific pressure. 2.
