1. Stainless steel 316 hex bolts are often used in quieter operating conditions. The petrochemical industry is commonly used in public works pipelines such as cooling water and air with low pressure temperatures.
Studs are divided into full-threaded studs and equal-length studs, of which full-threaded bolts have a higher load carrying capacity. There are some statements about the use of bolts in some industry regulations.
Basically, it is selected according to the pressure. The lower pressure can use hexagonal bolts, and the double studs can be used regardless of the pressure.
2. GB/T5782 hex head bolts and GB/T901 studs are used in non-toxic, non-combustible media and non-violent cycles. Hex head bolts can only be used where the nominal pressure rating is less than or equal to PN16.
, studs can be used for applications where the pressure rating is less than or equal to PN40.
The full-thread studs of the Ministry of Chemical Industry, the studs of the mechanical department, and the unequal-length studs of the national standard can be used in harsh conditions. Can be seen in the manufacturing process. The double-headed stainless steel 316 hex bolt has a much better compression resistance, because the hexagonal one must go deep into the material and then pull out when the knife is closed. There will be no double heads.
