Stainless steel head

Stainless steel head is a kind of used to seal stainless steel tube products.After the end of the pipe or over a period of two on the two ends of the pipe welding head do containers with a product.Similar products are blind flange, pipe cap, plug, etc.

Stainless steel head the other way: stainless steel straight edge sealing head, side of barrel screw, elliptical head, dished head, light head, all kinds of size head spin, and the size of the stainless steel head spin while, flat, hemispherical head spinning, spherical sealing the top.

Specification: Ф 32 MM - 6000 MM

Thickness: 1 mm - 60 mm

Use the standard

The size of the stainless steel head organization stress and the cooling speed of workpiece in the martensite phase transformation area, shape, material chemical composition and other factors.Stainless steel head organization stress change of the end result is that the surface tensile stress, heart of compressive stress, just opposite to the thermal stress.Practice has proved that any artifacts in the process of heat treatment, as long as there is phase change, the thermal stress and organization stress will occur.Only the thermal stress in the organization transformation had produced stainless steel head, and organizational stress is produced in the process of organizational change, in the cooling process, a result of the combined action of thermal stress and organization stress, is the real stress in the workpiece.

Commonly used criteria:

JB/T4746-2002

GB25198-2010 gb/T12459-2005 gb/T13401-2005

SH3408-1996.

Range of application

Stainless steel head application range: petroleum, chemical, pharmaceutical, electronics, heating, sewage treatment, textile, food, machinery, building, nuclear power, military industry, aerospace, pressure vessel industry, etc.

Matters needing attention

Stainless steel head attention

1, measuring head circumference.If the cylinder processing in advance, please ask factory is scheduled to head the size of the outer circumference;

2, please send head circumference quartiles, and seal the head in the barrel and marking;

3, will head and cylinder position welding, positioning welding anchor point please customers according to the diameter and thickness are optional;

After the completion of the 4, anchor point position welding, welding.
