Please advise the difference between pipe cap and head

Pipe cap is generally used for the end of the tube, the head is used for the upper and lower (vertical equipment) parts of the container equipment or the left and right ends (horizontal equipment) pipe cap is generally the size of the outer diameter, such as 219, 273, 325 and so on. Pipe cap is also known as the plug, cap, pipe cover, muffler, mounted on the pipe end of the external threads to cover the pipe fittings. Used to close the pipeline, the role of the same with the pipe plug, but the cap can be directly screwed on the pipe, do not need other fittings. Generally used in the tube is not the end of the sampling port, sampling is completed, to screw on the cap, in special circumstances, unscrew the cap, you can silk mouth connected to the tube, temporary continuous sampling or pumping.

The use of pipe caps is generally lower in the case of pressure, easy to dismantle the maintenance, high school pressure is generally not used in the case of pipe caps. Pipe cap including convex cap, cone shell, reducer section, flat cap and tight mouth design. Pipe cap parameters: stainless steel: 304304L316316L321 diameter: DN15-DN1200 wall thickness: SCH5-SCH160 standard: ASMEDINJISBSGB/TJBSHHG.

Pipe cap and head shape is almost the same, the material for the stainless steel is more, the size of the cap is relatively small, can be forged; head size is a little bigger! Generally pressed with steel plate, pipe cap is generally used for the end of pipe, head is used for the upper and lower (vertical equipment) parts of container equipment or left and right ends (horizontal equipment). Convex caps include: hemispherical caps, oval caps, disk caps and crown caps. From the point of view of force convex pipe cap from the hemispherical pipe cap gradually bad, but from the manufacturing difficulty, gradually good manufacturing.

Generally speaking, the head is the inner diameter, such as 1 meter, are referred to the inner diameter of the pipe cap on the transition part did not make the requirements (not like the standard oval), the general handbook can only be found in the diameter and length, and the straight side of the part of the longer. Pipe cap is just a pipe plug, DN more than 300 should be replaced by head, if pressure, to carry out strength calibration. Pipe caps are used in water, beverage, beer, food, petrochemical, nuclear power, machinery, medical equipment, fertilizer, shipbuilding, waterproof treatment, pipelines, etc. Packing: wooden crates, cartons Service: provide technical advice, guidance on installation, etc. Disc-shaped pipe caps at r to avoid splicing, will thin, high stress.
