1. The large-caliber water supply pipe is light in weight, convenient to transport, convenient to load and unload, and the construction cost is relatively low. The construction of seamless steel pipes is strong, and because of its relatively large weight, cranes and other aids are often used for construction. The density of pe pipe is much lower than seamless steel pipe, according to statistics, its density is less than 1/8 of seamless steel pipe.

2. In terms of connection, the installation of pe pipes should be simpler. Seamless steel pipes need to use welding rods when connecting, so the welding time is relatively long and the cost is relatively high. Under normal circumstances, the welding of pe pipes can be carried out according to the instructions, and the operation is convenient, while the welding of seamless steel pipes requires highly professional technical personnel to operate. When steel pipes are accepted, tools produced according to professional specifications are required. If the construction distance is long, the construction is complicated and the construction period is long because of the large number of connections. However, pe pipes can be easily and quickly socketed and connected with only a small fuser, and the construction period and cost are much lower than the former.

3. In terms of service life, everyone knows that steel has poor corrosion resistance, so seamless steel pipes must be anticorrosive, and the service life is generally about 30 years. The pe pipe has relatively strong corrosion resistance and does not require anti-corrosion treatment, and its service life is generally about 50 years.

4. The inner wall of the pe pipe is smooth, and the water delivery volume is relatively large, and the roughness value will not change much due to the long use time. The seamless steel pipe is relatively rough, and the longer the use time, the greater the roughness value.
