The difference between pipe nipple and pipe coupling

What is a pipe nipple? Pipe nipple is a length of straight pipe with male threads on both ends. It is one of the most popular category of pipe fittings. It is a connector or a coupling threaded on both ends. Pipe nipples are used to allow plumbing to be connected to a water heater or other plumbing. They are used to fit straight end hose or pipe. A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam.  The length of the pipe […]

The difference between NPT and BSP seals

Thread: noun. a helical ridge on the outside of a screw, bolt, etc. or on the inside of a cylindrical hole, to allow two parts to be screwed together. Pipe threads are either straight (parallel) or tapered, while both options have a couple of design options themselves – threads may be according to national piping standard or british standard; be right-handed (RH) or left-handed (LH). Neither NPT, nor BSP is superior to the other one and the selection is driven by a number of factors, including geographical location, equipment size and industry. Pressure systems on board of ships use BSPP […]

The production process of stainless steel pipe bend

According to the different manufacturing methods, the stainless steel pipe bend can be divided into three types, namely, the bending pipe, the punching pipe and the welded pipe. Which can be divided into two types of bending bending and bending. When the stainless steel tube for bending the pipe along the longitudinal direction under pressure, leading to pipe wall thickness of the pipe is shortened, the lateral pipe subjected to tensile, elongation, wall thinning and tube; center without force, deformation will not occur. The cross section of stainless steel tube is changed from round to oval. Bend in the production […]

What is Pipe fitting?

What is Pipe fitting? Pipe fitting is the operation of repairing or installing tubing or piping systems which convey gas, liquid, and solid materials occasionally. It also involves selecting and preparing tubing or pipe, joining it by several means and location and repairs of leaks. Fitters work with various tubing and pipe materials such as copper, aluminum, steel, plastic and iron. Pipe fitting is not referred to as plumbing although the two are related, but have separate trades. Stainless steel pipe fittings are made of stainless steel, so it is made of stainless steel pipe fitting, which contains: stainless steel elbow, stainless […]

The cutting processing technology of stainless steel pipe

Without influence on the surface of the stainless steel pipe, how to quickly cut stainless steel pipe? One way is to use a grinding wheel cutting, this is now use most a way of cutting, is actually with grinding wheel as the cutting tools for cutting stainless steel pipe, this way of cutting cost is the cheapest, but it is easy to produce many burrs after cutting, lead to later also need to add deburr process, if there is no requirement, some manufacturer of burr then this method is one of the most practical, the lowest cost. There is a […]
