Performance Of Stainless Steel Flanges
Performance of stainless steel Flanges
Stainless steel Flanges do not produce corrosion, pitting, corrosion, easy to wear. Stainless steel is one of the most powerful materials in building metal materials. Because stainless steel has good corrosion resistance, it allows the structural parts to permanently maintain the integrity of the engineering design. Chromium-containing stainless steel stamping Flanges also set the mechanical strength and high elongation in one, easy parts processing and manufacturing, to meet the needs of architects and structural designers. All the metal and the atmosphere will be the reaction of oxygen, the formation of oxide film on the surface.
Stainless steel Flanges and other steel welded pipe fittings, forged pipe fittings and steel Flanges sales, the main products are used carbon steel, austenitic stainless steel and alloy steel and other high-quality pipe at home and abroad Flanges, elbow, tee Four-way), with (partial) heart diameter tube (size of the head), elbow, tube cap, forged socket welding and threaded fittings. The products are used in the United States standard ASME (ANSI), the German standard DIN, the Japanese standard JIS, China GB / T, JB, SH, HG and other standards, but also according to customer requirements special difficult, non-standard, Series of stainless steel pipe fittings, stainless steel Flanges and other pipe fittings.
Casting Flanges, rough shape, accurate size, small processing, low cost, but casting defects (stomata). The internal structure of a crack (inclusions) is not good (if cut, the streamline is worse);
Forged Flanges are usually more carbon free than cast Flanges. They are not easy to rust. They are streamlined, relatively compact structure, excellent mechanical properties of cast Flanges;
Inappropriate forging processes can also lead to large or uneven grain, hardening cracking, and forging costs higher than casting Flanges.
Forging is more resistant to shearing and pulling than castings.
The advantage of casting is the ability to create more complex shapes and lower cost;
In the carbon steel Flanges forging Flanges has a certain working principle, in accordance with the production process and production process and the use of carbon steel Flanges has a certain working principle, its working principle is the use of carbon steel Flanges gasket insulation gasket insulation performance High strength carbon steel Flanges insulation, carbon steel Flanges both sides of the electrical insulation Flanges factory work. Mary iron and galvanized pipe commonly used (to save iron) than steel, stronger than the strength of iron. Low carbon steel and low carbon steel, low carbon steel carbon content, easy to accept a variety of processing such as forging carbon steel Flanges processing, welding and cutting, commonly used chain, rivets, bolts, shaft manufacturing, Shape forging process. Second to buy the product: first to determine whether the control medium is oil or water.
Stainless steel Flanges connection is to put two pipes, fittings or equipment, first fixed on a Flanges, between the two Flanges, plus pad, bolted together to complete the connection. Some pipe fittings and equipment have their own Flanges, but also belong to the Flanges connection. Stainless steel Flanges are threaded Flangesd and welded Flanges, which are a kind of disc-shaped part, the most common in pipe works, Flanges are used in pairs. In the pipeline project, the Flanges is mainly used for pipe connection. In the need to connect the pipeline, a variety of installation of a Flanges, low-pressure pipe can use the wire Flanges, 4 kg above the pressure of the use of welding Flanges. Low-pressure small diameter with wire Flanges, high pressure and low pressure large diameter are used welding Flanges, different pressure Flanges thickness and connection bolt diameter and quantity is different. Stainless steel Flanges are one of the most powerful materials in the building metal materials that do not produce corrosion, pitting, corrosion or wear. Because stainless steel has good corrosion resistance, it allows the structural parts to permanently maintain the integrity of the engineering design.
Flanges can not be stored for a long time, should be checked regularly, often on the exposed surface to be clean, remove dirt, cleanly stored in the indoor dry place, is strictly prohibited or open storage. Flanges ball valve, globe valve, gate valve when used only for full open or closed, do not agree to do with the regulation of flow, so as to avoid the erosion of the sealing surface to accelerate wear. Flanges easy to draw, easy to manufacture, low cost, widely used; but the rigidity is poor, it shall not be used for supply and demand, flammable, explosive and high vacuum requirements of the chemical process piping system and height, extreme hazards. Sealing face type has a plane and auricle. Flanges structure is simple, small size, light weight; close and reliable, the current ball valve sealing surface materials widely used plastic, good sealing, in the vacuum system has also been widely used; easy maintenance, ball valve structure is simple, the seals are generally activities Of the demolition and replacement are more convenient; in full or closed, the ball and the sealing surface of the valve seat and the media isolation.
