Spiral steel tube and T-welded steel tube are basically the same raw materials used for steel pipe, but they are very different in the production process. Spiral steel pipe: the spiral seam steel pipe is made by automatic double silk and double submerged a ...

What’s the casing pipe? The shape of the casing section is round, in large diameter pipes and is inserted into the oil well, fixed with cement to protect other equipment that is mostly made of iron and steel. The oil well must be designed to withstan ...

Seamless pipes and welded pipes are widely used piping products.Seamless pipes means the pipes have no welding or seam,but welded pipes have welds on the surface.Now i’ll tell you the difference between them,let’s see: Seamless pipes don’ ...

Spiral wound gasket is components of metallic strip,filler,and guide ring (outer and inner ring). Strapping material could be stainless 304,304L,316,316L or other materials as request. Filling Materials are flexible graphite,or PTFF,filling thickness usual ...

Flange gaskets are the important part in the piping system,which are used to connect flanges and play a sealing role.If the flange gaskets selection is not suitable,so that the pipeline often damaged will cause economic losses to the enterprise production, ...

EN10216-1 is the European Union standard for seamless steel pipes. Applications EN10216-1 seamless steel pipe is mainly used for boiler water pipe, smoke pipe, superheater pipe, air preheating pipe, etc. It is also utilized to produce pipeline, equipment, ...

The seamless carbon steel pipe is formed by perforating a steel ingot or a solid tube blank, and then hot rolled, cold rolled or cold drawn. Seamless carbon steel pipe plays an important role in steel pipe industry. The raw material of the seamless carbon ...

Closed die forging is also known as impression die forging.It is a forging process,and it involves two or more dies that contain a precut profile of the desired component.Forging in which the material is fully constrained in the cavity created by the upper ...

Open die forging is an important technique for many types of forging manufacturing.It allows rough and finishing shaping of metal, most commonly steel and steel alloys. It takes heated metal and compresses it between two dies. The metal is worked at temper ...

Warm forging is performed with the workpiece heated to a range that is generally above the work hardening temperature and below the temperature at which scale forms. The process fills the niche between the closer tolerance, but sometimes expensive cold for ...

Cold forging is one variation of the forging metal-shaping process that involves forming or shaping metal parts through a process of applying powerful, localized compressive forces. Cold forging is carried out with the metal generally kept at or slightly a ...

Hot forging entails the heating of a workpiece to about 75% of its melting temperature. This allows for the flow stress and energy required to form the metal to lower,effectively increasing the rate of production (or strain rate). Hot forging aids in makin ...

Press forging may be defined as the process of shaping a metal that is placed between two dies by applying mechanical pressure or hydraulic pressure. Press forging is usually done on a forge press – a machine that applies gradual pressure on the forg ...

Forging is the most commonly used process for pipeline products.When forging,an initially simple part, the billet, is plastically deformed between the two dies to obtain the desired final shape.In order to better understand and optimize the forging process ...

Forging process provides uniformity of composition and structure. Forging lead to metallurgical recrystalisation and grain refinement due to thermal cycle and deformation process. This strengthens the resulting steel products, especially in terms of impact ...

Both forging and casting are metal-working processes commonly used in industry. They are often not restricted to metals.The main operations of the two processes are different.In the case of forging, when a metal is in a solid state, it is treated with comp ...

Forging and casting are the processes of forming metal components with complex shapes through the deformation of metal materials, but the methods are different.Casting is a process in which metal is heated until molten stage and pour this liquid metal into ...

Forging is the application of thermal and mechanical energy to steel billets or ingots to change the shape of the material when it is in a solid state.Steel forgings are usually made by a series of compression processes under extremely high pressure, with ...

Galvanized steel pipe is steel that has undergone chemical processing in order to make it corrosion resistant,it refers to steel pipe coated with zinc. This coating protects steel from corrosion and extends the life of FPSO ships. The advantages and disadv ...

According to different production methods,the seamless steel pipe applied in FPSO can be divided into hot rolled pipe,cold rolled pipe,cold drawn pipe and extruded pipe.Here is a detailed description of these methods: Hot rolling seamless pipe is generally ...
