At present, China's American standard high-pressure socket stainless steel tee industry still has some problems. For example, China's American standard stainless steel tee enterprises are mainly low-level, small-scale, family workshop-style enterprises. In terms of products, due to repeated investment and insufficient technology introduction, the leading products of China's American standard stainless steel tee enterprises are still low-quality public products. At present, the various American standard stainless steel tees produced by Chinese enterprises generally have shortcomings such as external leakage, internal leakage, low quality appearance, short life, inflexible operation, and unreliable valve electric and pneumatic devices. At the international level in the early 1980s, some American standard stainless steel tees required for high temperature, high pressure and key equipment still depend on imports.
