Issues with drilling holes in stainless steel pipes
Thread Content
A DN300 stainless steel main pipe needs to have a hole made in it to install a DN250 branch pipe. Is it difficult to make a hole in a stainless steel pipe? Will cutting with a welding rod be very labor-intensive?
A few thick ones, will plasma work?
Can acetylene cut stainless steel? That can’t be right
If under pressure, it is recommended to install a reducing tee joint. Direct drilling results in large welding deformation and high stress. Plasma cutting is feasible; it’s difficult to remove slag from inside the tube. Use cutting blades for cutting, be careful for safety, and clean the area before welding.
Use an angle grinder to cut it – just cutting it at a beveled edge is the most convenient approach, and it results in fewer weld seams
Due to the large opening, it is necessary to install a reducing tee. Angle grinder disc for pipe cutting. Other methods can easily result in slag that is difficult to clean.
It’s not easy to cut stainless steel with acetylene gas
