Product Description
(casing) cap Other names: head, plug, hijab, tube cover, bulkhead. English (Pipe cap) Application: welded pipe end or mounted on the pipe end male thread to cover plugging the pipe fitting. For closing the pipeline, the role of the same plugs. Close to the form of blind, but blind is detachable block, welded pipe cap is not removed. Cap includes a convex caps, cone shell, adjustable segment, flat lid and tighten port design.
Convex cap comprising: a hemispherical cap, oval pipe cap, disc and ball cap crown cap. From the perspective of the force gradually bad convex caps from the hemispherical cap, but the difficulty of making point of view, good manufacturing gradually.
Stainless steel: 304 304L 316 316L 321 2520 310,317, and other materials.
Diameter: DN15-DN1200
Thickness: SCH5-SCH160
Standard: ASME DIN JIS BS GB / T JB SH HG, as follows: GB / T12459-2005, GB / T13401-2005, ASME B16.9, SH3408,
SH3409, HG / T21635, DL / T695, SY / T0510, DIN2617
Uses: water, soft drinks, beer, food, petrochemical, nuclear power, machinery, medical equipment, fertilizer, shipbuilding, water treatment, pipelines and other
Package: wooden boxes, cartons
Dish cap of r at avoiding splicing, will thinned, high stress.
When welding seam direction requires only allowed radial and circumferential. After the large cap may cancel this requirement. Stitching distance should request greater than 3δ, and not less than 100mm (HAZ is a high stress area, and in the chemical composition of the area will be burning. So to avoid high stress area, the region and the thickness of the relevant According to experience, the stress decay length greater than 3δ, and not less than 100mm). But the cooling equipment is difficult to meet this requirement, has its particularity.
After forming the splice head, splice welds shall be 100% ray or ultrasonic inspection, qualified level with the equipment housing away. The final shape of the weld inspection level, the same as the proportion of housing and equipment, high waste. Dome head
Dome head
Example: If the equipment housing is 20% detection, III qualified. That bulkhead splice welds and final weld is qualified III, welded joint coefficient is 0.85;
If the equipment housing is a 100% detection, II qualified. That bulkhead splice welds and final weld is qualified II, welded joint coefficient of 1
Therefore, although 100 percent bulkhead splice detection, but not the same quality level, with the housing of the device away.
But pay attention to the process manufacturing process:
The correct approach is: cutting (dash) - a small board makes up the board - forming - NDT
If you do not do testing prior to molding is wrong, we can not guarantee the quality of after molding products. That means the final NDT NDT
