Analysis: Steel-plastic composite pipe specifications and implementation standards

Steel-plastic composite pipe, the product of seamless steel pipe, welded steel pipe as the base pipe, the inner wall of high adhesion, anti-corrosion, food-grade sanitary type polyethylene powder coating or epoxy resin coating. The pre-treatment, preheating, internal coating, leveling, and post-treatment processes for the galvanized inner plastic-coated composite steel pipe are upgraded products of the traditional galvanized pipe. The steel-plastic composite pipe is generally threaded. So what are the specifications of steel-plastic composite pipes ? Are all steel-plastic composite pipes the same in size? The following table shows the general specifications of steel-plastic composite pipes.

Steel-plastic composite pipe price

The price of steel-plastic composite pipes is not static, and it is recommended that everyone choose construction materials and go to designated businesses to purchase them. Not only is the quality guaranteed, but after-sales service is also done well. Everyone can go to the internet to browse some webpages to check the prices of some building materials to determine the purchase options. They must also familiarize themselves with the national regulations on the use of building materials, meet the national requirements, and use steel-plastic composite pipe materials scientifically.

Plastic-plastic composite pipe sets what quota

1, if it is a threaded connection, you can use the "size of the galvanized steel pipe thread connection" subheadings according to the specifications, the main material is the unit price of steel-plastic composite pipe, the unit price of the pipe fitting contained in the fixed amount is calculated according to the quantity in the pipe fitting content table. Plastic composite pipe fittings price weighted average can be.

2. Now that some steel-plastic composite pipes are connected by grooves, the "steel pipe groove connection" quota shall be applied and the pipe fittings shall be counted separately.

Steel-plastic composite pipe connection

1. The steel-lined plastic pipe must be made in the production plant. The length of the pipe cannot be adjusted during the construction, resulting in inconvenient installation and high construction costs.

2. The flanges of steel-lined plastic pipes are prone to cracks due to thermal expansion and contraction, resulting in corrosion of external steel pipes.

3, the production process makes this type of pipe shorter length, more pipeline interfaces, more hidden leaks.

4, the price depends on the specific caliber and pressure requirements.

5, the former flange connection, the latter fused and flanged

Editor's summary: From the figure we can see that the size of the steel-plastic composite pipe seems to be the same as the ordinary plastic pipe and aluminum-plastic pipe, but the toughness of the foreign currency of the steel-plastic composite pipe and the smoothness of the inner wall are absolutely different from the ordinary Plastic tube and aluminum plastic tube. The smoothness of the inner wall makes it more resistant to impact, and the reduction in friction makes it more powerful. The outer wall of the steel wire composite pipe is also very beautiful. The appearance of the outer wall also adds a lot to it.
