Hur får man tag på högkvalitativa rörlock?
Pipe cap acts as protective device and are designed to protect pipe ends of various shapes. The main purpose of using pipe caps is to waterproof the connections. They are also used to close the the ends of hydraulic or pneumatic pipes and tubes. They are used in the plumbing apparatus of domestic, commercial and industrial water supply lines, machinery and processing equipment etc. They are also fitted on water pump lines with the sole purpose of removing air blocks. Pipe caps are highly demanded as an important category of pipe fittings. If a solvent-weld cap is used to provide for a future connection point, several inches of pipe must be left before the cap; when the cap is cut off for the future connection, enough pipe must remain to allow a new fitting to be glued onto it.
Pipe Cap is directly welded to die at the end of the pipeline; at the end of the pipeline can also welding flange, then with a blind flange to death, when necessary can open the blind flange, pipeline check inside.
The conventional cap holder with pressure pressing made by thick wall; forging; by spinning large diameter.
The need for maintenance or even after the connecting line, with blind, not later, with a pipe cap. With the blind plate has the possibility of leakage, there is a long time, and screw rust died, as useless, the heat pipe is not very easy to heat insulation.

Common Shapes of pipe caps:
Pipe caps are available in various shapes. Having an intense knowledge about the shape of pipe cap would be beneficial for the buyer. Some of the common shapes of pipe caps are:
- “U” Shape Cap
- “I” Shape Cap
- Hex Cap etc.
Features of pipe caps:
There are several important specifications that the buyer should consider before making bulk purchase of pipe caps. The important specifications that needs to be considered are:
- NPT (National Pipe Thread ) size: This feature is applicable for round shaped caps, wherein the object that has to be protected has a male NPT thread.
- BSP (British Standard Pipe) size: This size option is applicable only for round shaped caps, wherein the object to be capped has a male BSP thread.
- Diameter: Diameter is an important dimension that is applicable only for round caps and plugs. In case of fittings having straight threads, the most important feature to be considered is the major thread diameter. However, this dimension is not an important consideration when cap, plug or object to be capped has a tapered (NPT or BSP) thread.
- Shape: The dimension and shape of pipe caps are also very important points to consider. Pipe caps of different shapes have different features.
Some features are:
- A.Round Caps: Popular features of round caps are: flange, slotted head, knurled or faceted head, retaining head, and tear tab. A flange is meant for easy removal or additional protection of pipe or tube surfaces. Flanges also help to prevent accidental pushing away of the plug through the opening. Slotted caps can be easily installed or removed with the help of a screwdriver. Knurled or faceted heads are usually designed for threaded caps and plugs only. Knurls or facets offer hassle free installation and removal. Pipe caps provided with a tear-tab or strip are easy to remove.
- B.Square or Rectangular Cap: For square or rectangular caps, length and width are the most important dimensions to consider. For rectangular caps, the width is the smaller cross sectional dimension, whereas for square caps, the length and breadth are the same dimension.
Types of pipe caps:
Pipe caps come in many different types and the type vary according to the application. However pipe caps also vary depending on their construction features and it is very important for the buyer to know the right type of pipe cap. Based on construction, pipe caps are of the following types:
These caps are female threaded. The thread can be either straight or tapered, also referred as NPT. Generally, caps have a female thread and plugs have a male thread.
These caps have tapered sides, which offers a close fit. Some of these fittings can be used either as a cap or a plug. Tapered caps and plugs are multi-functional and go well with male and female NPT threads, straight tubes and bars; and male straight threads. These fittings have a tapered body to provide a secure and firm friction fit while facilitating easy removal. The tapered caps are designed to provide protection for all internal and external, threaded and non-threaded fittings against damage, dirt or moisture that can occur.
These caps are round in shape with a slightly square end. This prevents pipes and tubes from rolling.

The weight of pipe cap
I believe that when many people hear the word “rörlocks” for the first time will be tiny one leng. What is the pipe cap? What did it look like? What is the use? But for the mechanical workers this pipe cap is more common than the. In fact, the pipe cap is also called plug, head, pipe cap, bulkhead, the name of good let people understand. The pipe fittings are welded on the pipe end or are arranged on the outer thread of the pipe end to cover the pipe. Used to close the pipeline, the same role with the pipe blocking the same.
Blind in the form of a close, but the blind is blocked can be removed, and the welded pipe cap is not removable. The pipe cap includes the design of convex pipe cap, cone shell, reducer, flat cover and tight mouth.
The convex pipe cap includes a hemispherical, oval disc pipe cap, pipe cap and spherical pipe cap. From the stress angle convex pipe cap from the hemispherical pipe cap is not good, but from look on the manufacturing difficulty, has good manufacturing. And pipe cap from the use of classified material generally can be divided into several common copper pipe cap, iron pipe, stainless steel pipe cap, plastic pipe cap, pipe cap!
The pipe cap on the market are very much, because the industry is also very much, at present in many petrochemical, nuclear power, machinery, medical equipment, chemical fertilizer, shipbuilding, waterproofing treatment, pipe, water heating, solar water heaters and other industry need use to pipe cap!
pipe cap according to the classification of the pressure for about seventeen, and American Standard pipe pressure rating is the same, sch5s, sch10s, sch10, sch20, sch30, sch40s, STD, sch40, sch60, sch80s, XS; sch80, SCH100, sch120, sch140, sch160, XXS. The most commonly used is two kinds of STD and XS. pipe cap in the construction industry not very common, necessary pipe cap just in the end of the pipe for closed pipeline, and the blind plate uses basically the same is blind plate installed can be disassembled, but pipe cap can not disassembled, pipe cap is welded on the top of the pipe, and the blind plate in the form of very close to.
Above is the pipe cap of general use, actually a little attention point can see pipe cap can be divided into many types, so can not be generalized and pipe cap with the head on the literal meaning almost, in fact distinguish is not small: head for devices to a container under the (vertical) equipment part or left and right ends (horizontal) pipe cap are generally outside diameter, pipe caps can be screwed directly in the pipe, does not need other Rördelar.. So use pipe cap introduced today is here.
