Common flanges include flat welding flange, butt welding flange, socket welding flange, threaded flange. A new type of flange called anchor flange, anchoring flange is an engineering component. In places with less pressure can be replaced with a short tube with a thrust ring, or known as wall bushing, buried underground or life-long non-maintenance fixed pipe connection, and require a larger pressure, the conventional method Lan, can not ensure the safe and reliable work of high pressure pipe....
First of all, a paper mold (or plastic film mold) in which one section of a two-section 90-degree elbow with a diameter of 300 is developed is affixed to the steel tube and can be scored and cut. The dimensions of the unfolded drawing can refer to related sheet metal manuals. If there is no sheet metal manual, you can use CAD to draw the unfolded drawing. The methods are as follows: 1. Draw two sections of 90-degree elbows on the left for a total of one section, and draw 10 in the radial...
304 stainless steel tube full name SUS304 stainless steel tube SUS304 stainless steel tube belongs to the US grade material stainless steel tube, domestic brand equivalent to 0Cr19Ni9 stainless steel tube, usually with 0Cr18Ni9 instead. The mechanism of stainless steel rust prevention is that the alloy elements form a dense oxide film, which blocks oxygen contact and prevents further oxidation. So stainless steel is not "stainless." The rust phenomenon of 304 materials may be due to the...

Piping material selection mainly depends on process conditions such as Fluid it transports; at what temperature at what pressure it transports. Let’s try to understand this condition in depth. 1st, Process condition that will impact the selection of material is type of fluid it transport. For corrosive fluids, you have to go for higher corrosion resistance material as compared to non-corrosive service Corrosive fluids such as – crude oil, Sea Water, H2S, Ammonia, Acids etc. required high...
Long Weld Neck Flanges The Long Weld Neck Flange is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the Steel flange. The Long Wn Flange are the best designed butt weld pipe fitting of those currently available becuase of its inherent structural value. It is expensive because of the design. Details of Asme B16.5 Socket Weld Pipe Fitting flange 1. Socket Weld flange 2. Filled weld 3. Pipe X =...
introduction For the requirements of the outer diameter accuracy of hot-rolled steel pipes, the current national standard GB 3087-82, GB 5310-95, GB 8163-87 and American standard ASTM A 53-93a are greater than or equal to ±1.0% of the nominal outer diameter of the steel pipe. The ellipticity of the hot rolled steel pipe (ellipticity = (Dmax - Dmin) / Dm, Dmax, Dmin - the maximum and minimum outer diameter of the same section of the steel pipe, Dm - the nominal outer diameter of the steel pipe)...
1. Counterfeit pipes are prone to collapse. Folding is a variety of fold lines formed on the surface of the steel pipe, and this defect often runs through the entire product. The reason for the folding is due to the high efficiency of the shoddy manufacturers, the large amount of reduction, the generation of ears, and the folding of the folded products. The folding products will crack after bending and the strength of the steel will drop. 2. Counterfeit steel pipe surface often has pockmarked...
Step 1: Construction Staging Areas & Storage Yards In order to construct a pipeline, staging areas and storage yards are cleared, strategically located along the planned right-of-way. These areas are used to stockpile pipe and to store fuel tanks, sand bags, silt fencing, stakes, and equipment parts. They provide parking for construction equipment, employee trucks, and locations for office trailers. Staging areas are cleared and covered in rough stone gravel, often reinforced with large...

ELBOWS: Mandrel method (Hot Forming) One of the most common elbow manufacturing processes for manufacturing Elbows from the pipe is mandrel method which is kind of hot forming methods. In this method, a pipe is cut in pieces and push with the help of hydraulic ram. Induction heating coil heat the pipe and, it is pushed over a die called "mandrel" which allows the pipe to expand and bend simultaneously. This method can be used to manufacture a wide range of the diameter of elbows. In this...
Grooved pipe fittings have been widely recognized by customers for its convenient installation and good performance. There are many product manufacturers selling grooved pipe fittings on the market, and the product quality is also uneven. When consumers purchase grooved pipe fittings, they have to What is a good way to identify? 1. Tap the surface of the grooved pipe fitting by hand to check the toughness of the pipe. If you tap the outer wall of the pipe, the surface of the pipe will have a...

One of the butt welded pipe fittings is a pipe fitting made of welded pipe. For the pipe fitting manufacturer, the forming process using the welded pipe is basically the same as that of the seamless pipe, and the forming process of the welded pipe fitting does not include the welding process; the other is The welding process required for the pipe fittings to complete the pipe forming is one of the flanged pipe fittings. It is widely used and promoted in different fields and industries. The...
National pipe thread American National Standard Pipe Thread standards, often called national pipe thread standards for short, are U.S. national technical standards for screw threads used on threaded pipes and pipe fittings. They include both tapered and straight thread series for various purposes including rigidity, pressure-tight sealing, or both.[1] The various types are each named with a symbol and a full name; examples of the symbols include NPT, NPS, NPTF, NPSC, and others. MIP is an...
3LPE Coated Pipes 3LPE Coated Pipes consist of 3 layers for pipeline coating. Layer 1 consists of Fusion Bonded Epoxy. This later provides protection against corrosion and is fusion bonded with the blasted steel surface. Layer 2 is a copolymer adhesive which has excellent chemical bonding to the inner layer and the top layer of polyethylene. Layer 3 is the layer of polyethylene used for protection against any physical damage of the pipes. The 3 layer polyethylene coated pipes are the preferred...
When selecting fastener materials for flange connection, factors such as pipe operating pressure, operating temperature, media type, and gasket type should be considered. The type of gasket, as well as the operating pressure and operating temperature, directly impose requirements on the strength of the fastener material. For example, the flange connection of a low-pressure, highly toxic medium pipe sealed with a wound gasket, although the operating pressure and temperature of the pipe are not...
Steel Pipe Knowledge: 4 Ways to Keep Straight Seam Steel Pipes 1, choose the appropriate venue and warehouse (1) The site or warehouse where steel pipes are to be stored should be located in a clean, well-ventilated area away from factories and mines that produce harmful gases or dust. Remove weeds and all debris on the site to keep the steel pipe clean (2) In the warehouse, it is not allowed to pile together materials that are corrosive to the steel, such as acid, alkali, salt, and cement....
