Seamless 316 Stainless Steel Tubing, Up To 4660 PSI

Description & Features

Application	Please review important safety & application information starting on
Note	A 6:1 safety factor is used in table below for applications where “considerable” hydraulic shock and mechanical strain are present. For applications where hydraulic shock and mechanical strain is not excessive, a 4:1 safety factor (higher working pressures) may be carefully considered. For applications where hydraulic shock and mechanical strain is severe a 8:1 safety factor (lower working pressures) should be applied. Tubing design pressures have not been de-rated for elevated operating temperatures. Contact us for application information regarding elevated temperatures. Tubing is stocked in 20 foot nominal lengths.
Pressure Rating	Based on using the more conservative Barlow formula where P=(2TxS)/O (P=burst pressure T=wall thickness S=tensile strength O=outside diameter).
Tubing Material Specifications	ASTM A269 B90 Seamless. Bright Annealed 316 Stainless Steel. Tensile strength 75,000 psi.
Warning	Refer to safety information regarding proper selection of tubing and tube fittings starting on
