Expansion joints are primarily used to absorb pipeline expansion due to longitudinal-thermal stretches where expansion joints are unwilling or inappropriate to use. Slip-type expansion joints have a lining that slides into the body. Leakage is controlled by the packing located between the liner and the body. These joints include a cavity and a bullet with the seals inserted between the two parts. Expanded shot joints can inhibit axial and angular rotation but cannot tolerate axial movements. These joints can be metal or plastic. They do not have pipes. Basically these joints have hand blowers or corrugated grooves that expand and shrink to absorb the expansion of the piping system. In this article we talk about different types of pe pipe joints.

Advantages of stainless steel pipe joints
Stainless steel is a nickel chrome alloy that is manufactured in a wide range of products including steel pipes and steel pipes. Corrosion resistant and easy to maintain. The choice between these two materials depends on how the pipe is used and the environment in which the pipe is installed. Stainless steel pipes are iron-based alloys that usually contain chromium. Other elements, most importantly nickel, are added to this alloy to create important properties in combination with chromium. High temperature stainless steel is highly resistant to corrosion and oxidation. In general, with increasing chromium content, corrosion and oxidation resistance (not proportionally) gradually increases. You can find poly pipe fusion procedures in many markets.
Stainless steel tubes are used for a variety of reasons: corrosion and oxidation resistance, high heat resistance, low maintenance costs, maintaining the purity of the materials that come in contact with stainless steel. In the design of stainless steel thin-walled pipes, due to the inherent properties of stainless steel, there is no fear of failure due to corrosion. Stainless steel tubes can be manufactured in either welded or seamless form. You can buy hdpe pipe flange connections from online stores.

Best PE pipes for irrigation systems 2019
The most widely used polyethylene pipes in the world under pressure irrigation are the best and most resistant types of pipes. These pipes are either drip pipes or drip pipes that drain water at low pressure and flow through the plants. These pipes are manufactured in sheets of 400 to 500 meters and weigh from 10.5 to 21 kg. They are about 16 mm in size and have a class of 4 atmospheres.
These tubes are highly resistant to infrared and ultraviolet rays, and their color remains stable to the sun’s rays. These tubes have high flexibility and are not capable of bending, fragility, crushing, cracking, and high resistance to rot. In the vicinity of chemical fertilizers, acidic substances and nitrates such as nitrates, these pipes do not corrode and the water flows easily and without friction. Due to the smooth surface inside the pipe, it will not be possible to clog sludge and sediment.
Newest technologies for producing high quality pipe joints
The process of producing polyethylene pipes is by extrusion method. The melted material is then pushed forward by a screw (spiral rod) and then inserted into the mold after leaving the extruder. The cooked materials pass the calibrator after leaving the mold and are formed in a vacuum tank with appropriate pressure. The pipe surface is cooled by layers of cold water as soon as it exits the calibrator. The high temperature of the polyethylene melt decreases gradually after leaving the mold in the vacuum tank and then in the cooling tanks using cold water. The polyethylene pipe produced by the landing gear is gradually drawn from the vacuum and cooling tanks and registered by the marking machine, technical specifications, production date, standard mark and the trademark of the company and then cut by the cutting machine. Different and certain areas are cut. All production processes are controlled and monitored by fully automatic devices to ensure that the quality of the finished product is acceptable and within the company name and standards.

How HDPE pipes are joined?
Connecting polyethylene pipes using cross welding or butt welding is a thermophysical process. This method involves continually heating the contact surface of two polyethylene pipes until they are permanently bonded to each other. These two parts heat until they are well melted. These melted parts are then merged to form a pipe at the junction so that the flow can flow well. The two levels are controlled together under pressure and cool for a certain period of time. The uniform and ideal welding of the two tubes occurs after the cooling phase. The joint is resistant to pressure and has no pores. This section will have the same operating pressure as other parts of the pipe. Following the above steps, the polyethylene pipes will be mounted on special clamps and the contact surface will be uniformly cut using the welding tool.
At the junction and between the contact surface of the two pipes there should be no gaps or pores. Then, using a hydroelectric system, a controlled pressure is applied at the junction until the pipes begin to melt and the materials at the junction create bumps of 1 to 2 mm. During all these stages, it is important to ensure that the hot and melt surface of the pipes does not touch the heating plate. Then remove the heating plate between the two tubes and carefully melt the two parts of the tubes. This step must be performed under controlled pressure. Until the cooling surface is fully cooled, the pipes must remain under initial pressure.
What is polyethylene pipe made of?
Polyethylene is the chemical synthesis of ethylene, which is usually made from a combination of crude oil and natural gases. Some of its unofficial names are polythene or polyethylyne, also referred to as PE. Polyethylene is mostly used to make plastic compounds for pure use. Although it is used in a wide range of uses. Polyethylenes are a family of thermoplastics obtained by the polymerization of ethylene gas (C2H4). The catalyst and polymerization method of this material can control various properties such as density, melt flow index (MFI), crystallinity, branching and lattice degree, molecular weight and molecular weight distribution. Low molecular weight polymers are used as lubricants. Medium molecular weight polymers are miscible waxes with paraffin.
Is HDPE stronger than PVC?
Hollow membrane liners are very low permeability membranes that are used to prevent fluid migration in engineering projects. The pvcs have three types of thermoplastic, thermostable and hybrid polymers that pvc are thermoplastic polymers. This type of PVC is the most used PVC in the world for sealing in various uses such as landfills, buildings, tanks containing hydrocarbons and so on. The main reason for its use is its high chemical resistance (due to its crystalline structure) as well as its very good mechanical properties. The usual thickness of this type of pvc is about 1.5 mm which is available in the range of 0.75 to 3 mm thick. Due to the highly linear structure of pvc polymers, the polymer chain accumulation is very high and therefore little room for fluid penetration is available. As a result, pvc has a very low permeability so that it can be impermeable in the absence of rupture and failure.
