Pickling and passivated  thread 304 stainless steel seamless pipe 
stainless steel seamless pipe  in about (6 & 3) meters lengths of Stainless Steel 316L to ASTM
A312/530 properly annealed and passivized of DN 6 5/8” with 7.11 mm (0.27992 inch) wall thickness.


Both ends of the pipe shall be threaded to API 5B buttress threads. One side provided with a seamless 

coupling to ASTM A 451 grade 316L mounted hand tight with 3/8" taper in one foot (1/32" in one inch) to reduce the make up torque.


The threads shall be treated by copper plating for anti-galling by a qualified and nominated factory which will guarantee the make and break of the joint of ten times.
