Why is the valve always malfunctioning, is it a quality problem or an operatio……

Why is the valve always malfunctioning? In the entire process of design, manufacture, installation, working conditions, operation and maintenance, every step cannot be relaxed. Before the valve leaves the factory or complete installation, how to determine if there is a problem? This requires inspection through visual inspection and certain performance tests. Through these test results, the defects can be exposed and adjusted accordingly. Only after all the tests are qualified can they be put into use. So, what kind of details need to pay attention to appearance inspection? What are the performance tests? Let’s take a look with the little […]

How to make seamless steel pipe

How to make seamless steel pipe? The advent of rolling mill technology and its development during the first half of the nineteenth century also heralded in the industrial manufacture of tube and pipe. Initially, rolled strips of sheet were formed into a circular cross section by funnel arrangements or rolls, and then butt or lap welded in the same heat (forge welding process). Toward the end of the century, various processes became available for the manufacture of seamless tube and pipe, with production volumes rapidly increasing over a relatively short period. In spite of the application of other welding processes, […]

ASTM A519

ASTM A519 specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The seamless tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and properties. The tubes shall be furnished in the following shapes: […]

How to get high quality ASTM A333 alloy pipes

What is a ASTM A333 alloy pipe? ASTM A333 (ASME S/A-333) alloy pipes grades permit low temperature service. This specification covers nominal (average) walled pipe almost exclusively in seamless.  Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse effect on low-temperature impact properties. Main ASTM A333 alloy pipes: ASTM A333 Grade 1 Seamless Pipe ASMT A333 Grade 1 seamless and welded pipes shall be treated to control their microstructure. Tensile tests, impact tests, hydrostatic tests, and nondestructive electric tests shall be made in accordance to […]

How to get high quality stainless steel flange

What is a stainless steel flange? A stainless steel flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. stainless steel flanges are usually welded or screwed. stainless steel flanged joints are made by bolting together two stainless steel flanges with a gasket between them to provide a seal. What is stainless steel? This crystal structure makes such steels non-magnetic and less brittle at low temperatures. For higher hardness and strength, carbon is added. When subjected to adequate heat treatment these steels are […]

What are the advantages of stainless steel welded pipe with welded seam pickling

As the demand for stainless steel materials is more and more widely used, stainless steel welded pipes, as one of the applied varieties, are also widely used in various industries. As the stainless steel industry welded pipe, because of the different surface treatment, there are two kinds of welded pipe and polished pipe. Below are the principles and advantages and disadvantages of the two kinds of welded pipes. The welded pipe with welding seam is welded by automatic welding, one side welding is formed on double side, and the weld on the pipe is smooth and smooth. Because the pickling […]
