the question “shall i use erw or seamless pipes for my project?” is coming up over and over. each of the two has different advantages and disadvantages, which should be pondered to take a proper decision:seamless pipe pros and cons

as there are many types of steels, the chance of developing a conflict is guaranteed. different kinds of steel are made of various components. besides, they are different in their use and durability. if you know the manufacturing story, you can quickly determine how it will be useful for y

roughly speaking, seamless steel pipe manufacturing process starts with a solid, round steel billet. this billet is then heated to great temperatures and stretched and pulled over a form until it takes the shape of a hollow tube. it is different from the welded pipe which is produce

one of the most common applications of nickel is to join as a major ingredient in the production of stainless steel, especially austenitic stainless steels. like chromium, nickel plays an important role and is an indispensable element of the outstanding features of stainless steel that we

alloy flange materials (chrome-moly) have higher chrome and molybdenum content than carbon steel flanges. alloy steel flange materials suit high temperature and high-pressure applications and improved resistance to corrosion when compared to regular carbon steel flanges grades.<

the term “duplex” refers to a family of stainless steels that have double structure – i.e. they are neither a fully austenitic ss structure, like 304 stainless, nor a standard ferritic, such as the 430 series.duplex stainless steel (uns s31803/uns s32205) has been deve

what is the raw material required for manufacturing seamless & erw stainless steel pipes? seamless steel pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. billets are procured both from indigenous supplie

astm a36 steel plate is one of the most common grades of steel used in structural applications. this mild carbon steel grade contains chemical alloys that give it properties such as machinability, ductility, and strength that are ideal for use in constructing a variety of structures.

washington/brussels - the united states and the european union (eu) have agreed to use a tariff-rate quota (trq) system to help resolve their three-year disputes over us tariffs on steel and aluminum imported from the eu.the united states will replace the existing tariffs on eu steel and a

while there are thousands of different alloys of stainless steel, they can all be divided into three broad categories:1. austenitic stainless steels. these are the most frequently used types of stainless steels. austenitic stainless steels tend to have a high chromium cont

duplex stainless steelduplex steel also known as duplex 2205 stainless steel is a two-phase, ferritic and austenitic steel with 22% chromium (22cr duplex) 3% molybdenum, 5 to 6% nickel alloyed stainless steel also known as x2crnimon22-5-3 used extensively in applicatio

stainless steel is often referred to as corrosion-resistant steel – it does not stain, corrode or rust as easily as normal carbon steel. it would however be misleading to say it is corrosion-proof. it differs significantly from standard carbon steel due to the amount of chromium present, w

grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. the molybdenum gives 316 better overall corrosion resistant properties than grade 304, particularly higher resistance to pitting and crevice corrosion in chloride enviro

1. grinding wheel cutting: this is the more commonly used method at present, that is, cutting with a grinder, but there will be more burrs on the pipe port after cutting out. if a fully automatic stainless steel pipe end c burr removal machine can be used in conjunction with the cost cheap

mss sp 75 is the standard specification for high-test, wrought, butt-welding fittings which covers factory-made seamless and electric fusion-welded carbon and low-alloy steel butt-welding pipe fittings for use in high-pressure oil and gas transmission and distribution systems, including pi
