Is there any solution to the issue that the steam inlet pipe of the heat exchanger is too close to the plastic pipe from which the material is being heated?

The steam inlet pipe of the heat exchanger is too close to the plastic pipe that contains the material being heated (the plastic pipe can withstand temperatures of around 80°C, while the steam has a temperature of around 150°C). Is there any solution to this issue?
Replace the section of plastic pipe that is close to the steam with a steel or stainless steel pipe.
It’s mainly that plastic flange; why are the flanges at the tube ends of the plate heat exchanger arranged in an interlaced pattern, so close to each other?
Steam pipes should be covered with insulated aluminum sheeting lined with insulation material to provide better protection.
It seems that switching to stainless steel would be more appropriate
Heating medium: 2% hydrochloric acid, temperature 50 degrees Celsius
As expected, the part of the pipe near the steam pipe has been changed to a material identical to that of the equipment. Plastic pipes are still used after moving away from the steam pipes. It avoids wasting materials and solves the problem at the lowest possible cost.
Is such a plastic tube okay? We still often use steam to clean such pipes here, and nothing goes wrong.
Insulate the steam pipes, and replace the section of pipe from the plastic flange to the elbow with stainless steel
