316L Stainless Steel Compression fitting to tube socket welding head

The 316L Stainless Steel Compression Fitting to Tube Socket Welding Head is a high-performance connection element designed specifically for demanding industrial piping systems. Its design combines the advantages of compression fittings and tube socket welding heads. The compression fitting section uses a nut and double inner tube rings to achieve a tight clamping and sealing of the pipe. Some models can also be equipped with fluororubber or PTFE sealing rings to enhance sealing performance, making it particularly suitable for high-pressure or high-purity media environments. The tube socket welding head section uses a high-precision welded sleeve, forming a high-strength mechanical connection to the pipe end via TIG or MIG welding processes. The internal weld seam design features a smooth transition, effectively reducing fluid turbulence and media buildup, making it suitable for systems with high cleanliness requirements.
