Analysis of stainless steel head
The stainless steel head is coated with anti-corrosion material, and then the storage life of the anti-corrosion material is tested. The whole process must be careful of the actual operation and wipe the symmetry.
According to the requirements, the stainless steel conical head should be infiltrated and tested before the original factory. Before using penetration detection, warm reminder to clean the top surface of the head.
In addition, according to the specifications of the stainless steel head manufacturer, the appearance of the stainless steel head design is beautiful and generous, the structural reliability is high, can bear the corrosion of a variety of chemical substances, the surface moisture and rust treatment, the service life is increased by 3 times.
The shape of the head must be checked with full pattern.
Shape tolerance: external convex is not greater than 1.25%Di, concave is not greater than 0.625%Di.
The inner radius of the ITD shall not be less than the value specified in the drawing.
