Straight-type Steel-Plastic Transition Fitting
Our Straight-type Steel-Plastic Transition Fitting connects PE plastic pipes to steel pipes. It works well for city gas and water projects. We have made these fittings for over 30 years. We learned from coastal areas that high humidity causes rust and cracks. So we added a thicker anti-corrosion coating on the steel parts. This coating stops rust and leakage. Many coastal gas companies now use our Straight-type Steel-Plastic Transition Fitting without any issues. This fitting solves a common problem in the industry.

Reliable Transition Solution
Our Straight-type Steel-Plastic Transition Fitting connects PE plastic pipes to steel pipes. It works well for city gas and water projects. We have made these fittings for over 30 years. We learned from coastal areas that high humidity causes rust and cracks. So we added a thicker anti-corrosion coating on the steel parts. This coating stops rust and leakage.

Strict Quality Control
We check every product three times during production. First, we check the first piece. Then we do random checks during the run. Finally, we check every piece before it leaves the factory. For this Straight-type Steel-Plastic Transition Fitting, we focus on two key points. One is the bonding strength between steel and PE plastic. The other is the coating integrity on the steel surface. We run a pull test and a leak test on each fitting before shipping. These tests stop the pipe from pulling apart or leaking later. Our quality system keeps the product safe and reliable.
Full Size Range and Support
The table below shows all sizes we offer. The main sizes go from DN20 to DN400. For example, size 110×89 (Order No. SW110/89) has D=120mm, total L=480mm, and steel end L2=240mm. These numbers help workers weld and position the pipe on site. We also give full warranty service. If you have trouble during installation or testing, our team gives you technical help right away. We want your project to go smoothly from start to finish.
