To change from one to the other, half the surrounding bolts need to be removed and the Spade or Spacer is swapped over. We therefore assure that all products we supply are tested rigorously to each of our client’s specifications. Buttweld fittings are defined in the ASME B16.9 standards, with light-weight corrosion resistant fittings made to MSS SP43 specifications. JavaScript is disabled in your browser. Forged fittings can withstand higher pressures in more extreme conditions, Forged fittings have a longer and typically more reliable life expectancy than casted fittings, Forged fittings are usually less expensive than casted ones. A Raised Face Flange has a very specific purpose; To concentrate more pressure on a smaller gasket area and therefore increase the joint’s ability to contain the pressure. Our extensive range includes ERW, LSAW, DSAW, Spiralweld and Seamless steel pipes, so you can be sure that whatever your project requirement or timing, we can provide you with exactly what you need. Service was professional and the cost of materials competitive. This means that as long as a welded pipe’s specified tolerances for temperature and pressure aren’t surpassed, there is no reason why is shouldn’t perform just as well as a seamless pipe in a wide array of sectors. Speak to one of our global sales teams today. This is because they give the ability for the flange to swivel around and to align bolt holes which simplifies the assembly of large diameter or unusually stiff piping. Similarly, for added corrosion protection, different coatings can be used such as galvanising, aluminising and claddings. For smaller spades and spacers, it is common for the spacer to have a hole in the handle and the spade to have no hole. Spectacle blinds, spades and spaces are a cheap and robust alternative to valves. All the buttweld fittings that Special Piping Materials sources and supply meet the requirements of the oil, petrochemical, water treatment and other allied industries. This, in turn, creates a an extremely tight and leak-proof, metal-to-metal seal. Crosses: As you would expect, crosses are a 4-way fitting. This process means that a welding filler material isn’t required.

Special Piping Materials is able to source the best precision-engineered weld-neck, blind, slip-on and lap joint flanges from manufacturers across the world. The Submerged Arc Welding (SAW) process of creating a welded pipe is often used in industries where thick steel sheets are involved or where long welds are required. Ends can be socket welded (SW) or threaded (MPT/BSPT). In many applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the substance inside must differ from the substance outside in composition or pressure. For more information about our range of welded pipes, contact your SPM sales office. Welded Stainless Steel Pipe – UNS S31600 / S31603 / 316/L; Welded Duplex Steel Pipe – UNS S31803 / S32205 /1.4462; Welded Super Duplex Steel Pipe – UNS S32760 / S32750 / SAF2507 / 1.4501 / 1.4410; Welded 6% Moly Pipe – UNS S31254 / 1.4574 / N08926 These are often key components of clients’ orders and SPM prides itself on its ability to be able to deliver them quickly and to the required specification. Seamless pipes are thought to be able to withstand higher pressure, higher temperatures, higher mechanical stress and a corrosive atmosphere. The production of our seamless steel pipes is tightly regulated and all of the pipes we stock have been fully tested to international standards to ensure we only supply the highest quality products. This is especially important if you are flanging together different metals, for example stainless steel and carbon steel. A welded system uses comparatively less space that the other alternatives. We specialise in manufacturing structural and precision RHS, CHS & SHS tube and pipe. Here at Special Piping Materials we supply many different types of flanges, some of which we have detailed below. Here is a full list of the spectacle blinds, spades and spacers that we stock, in a range different material: Our spectacle blinds, spades and spacers come in pressure ratings of: Special Piping Materials’ spectacle blinds, spades and spacers are manufactured in accordance with the American Society for Testing & Materials (ASTM) Standard as follows: The dimensional standard of the spectacle blinds, spades and spacers we supply are in accordance with the American National Standards Institute (ANSI): *We can also quickly source and arrange delivery of sizes up to 72” (DN1800). Also, the exchange rate between AUD and USD plays a factor in Australian metal trading. All our products are packaged according to an engineering or project specification and short delivery times can be met where required. Therefore we offer only high-quality products meeting ISO Standard international quality standards. These operations include the following: The wide range of applications demonstrates the robustness of a buttweld fitting and how much this particular type of fitting is relied upon. This also means it is self-actuating – so the sealing pressure increases as the process pressure increases. Duplex Bar is not often used as simply a straight length of bar (although sometimes it can be). Cost effective compared to the counterpart fittings in the threaded or socket weld varieties. They have one inlet and three outlets or vice versa and allow for four pipes to meet together. For added corrosion protection, different metallic coatings like galvanising, aluminising and claddings can be used. They are generally considered to be the most robust welding fixture, no matter what industry is using them. ASSDA could not continue without the valuable support of its sponsors and more than 180 member organisations who work with ASSDA to grow the market for stainless steel. A benefit of using a Ring-Type Joint Flange is that the groove within the flange ensures the ring centres itself when the bolts are tightened. We are a well known manufacturer, supplier and exporter of top quality of Stainless Steel & Carbon Steel Flanges, Buttwelded Pipe Fittings, Pipes and … There are many advantages of forged fittings as opposed to casted fittings. Spectacle blind, spades and spacers are mainly used to provide flexibility during operation and maintenance. When the bolts connecting the flanges are tightened, the gasket is compressed between the flanges into the grooves. Instead of using a gasket between connecting flanges, Ring-Type Joint Flanges have grooves cut into their faces with steel ring gaskets. They are also heat treated to remove residual stresses and to achieve specific mechanical properties. As a leading supplier of stainless steel and alloy welded pipes, we can supply our clients with the following: Welded pipe manufacturing techniques are thought to have greatly improved over the past few years. It is not unusual for a Blind Flange to block off a nozzle for pressure tests in a plant, or simply because not all of the nozzles within the piping system are required at all times. To allow this to happen, they are specifically manufactured so that their inside diameter is slightly bigger than the pipe’s outside diameter. We can provide Stainless Steel, Nickel Alloy and Duplex Round Bars in the following diameters. They come in different head types, such as hex, square, and round. In stock in our warehouses around the world, we have the following size available: We can also quickly source and arrange delivery of sizes up to DN 1000mm. Rather, it is usually cut to an appropriate size and ‘worked’ to make nuts, bolts, flanges, reduction couplings or even complete valve housings.

Edcon Steel Australia's leading steel and metal … They work to the most exacting standards to ensure the quality of the products that they forge. While it is correct that the seam in a welded pipe makes it theoretically weaker than seamless pipe, manufacturing methods and quality assurance procedures are far more superior these days. Welded tubes and pipes are generally more cost effective than the equivalent seamless versions as well. h._hjSettings={hjid:206556,hjsv:5}; Sizes, Materials and pressure ratings the following diameters being joined to this... we have a Long life.
