DN800 steel pipe installation how long is an expansion joint

1. The length of the expansion joint of DN800 steel pipe installation is about 400mm.

2. Expansion joints can also be called pipeline expansion joints and expansion joints.

Compensators, retractors.

Expansion joints are divided into: corrugated expansion joints, sleeve expansion joints, square natural compensation expansion joints and other major types, among which corrugated expansion joints are more commonly used, mainly to ensure the safe operation of pipelines.

3. The development of steel pipe production technology began with the rise of bicycle manufacturing, the development of oil in the early 19th century, the manufacture of ships, boilers and aircraft during the two world wars, and the Second World War.

The manufacture of post-thermal power boilers, the development of the chemical industry, and the drilling and transportation of oil and gas have all strongly promoted the development of the steel pipe industry in terms of variety, output and quality.

1. The expansion joints used for pipelines are all molded products, and there are generally two types of products in China, 1 is stainless steel bellows type, and 2 is rubber bladder type.

2. The expansion joint is a kind of pipe fittings, and it has two important indicators: 1) The nominal diameter (that is, the dn you have given) is the nominal pressure pn, and you have not given it.

3. According to my estimation of your 800 tube, the general pressure will not be very large, I will give you an estimate of less than 8kg, the length of this expansion joint is about 400mm.

Expansion joints, also known as expansion joints, are used to compensate for the displacement caused by thermal expansion and contraction of pipelines.

There are many types of expansion joints, and the expansion joints in the form of carbon steel are also called flange loose sleeve expansion joints.

Expansion joints in the form of rubber are also called rubber flexible joints.

The expansion joint in the form of stainless steel is also called the stainless steel corrugated compensator.

Different products have different expansion joint lengths.

How long is the specific DN800 steel pipe installed This problem varies by different factors such as the temperature change of the product, the internal pressure of the product, and so on.

Gongyi Jiankun Water Supply Equipment Factory produces expansion joints all year round.

This depends on the temperature of the medium in the pipeline, the installation distance is close if the temperature is high, and the installation distance is farther if the temperature is low, and the installation distance is about 200 meters.

Summary. If it is a horizontal pipe, it needs to be connected with the steel pipe when setting. If the length exceeds meters, then a telescopic joint should be installed every 3 meters.

Pro, DN200 steel pipe 4 meters to install expansion joints.

There is a riser, when it is installed, it can pass through the floor part and play the role of fixing and supporting. If the length does not exceed 4 meters, each layer of the light should be equipped with one should be set. In addition, the maximum spacing between expansion joints should be 4 meters, and one should be set every 4 meters.

If it is a horizontal pipe, it needs to be connected with the steel pipe when setting. If the length exceeds meters, then a telescopic joint should be installed every 3 meters.

Expansion joints are widely used in gas pipelines, because gas has a certain amount of heat, in order to reduce the change in temperature, it is necessary to set up a friendly contraction joint, so as to alleviate the push and pull force caused by thermal expansion and cold contraction of the pipe chain.

DN600 steel pipe can be set with 2 4 expansion joints. An expansion joint should be installed at each end of the steel pipe, and whether the expansion joint is set in the middle depends on the situation. DN600 steel pipe can be installed with nominal diameter DN200 expansion joint, Changxiang smile degree of 210mm, axial compression of 25mm, axial stretch of 14mm, horizontal lifting shed displacement of 15mm, deflection angle is 15°.

DN200 expansion joint.
