Closed die forging is also known as impression die forging.It uses two or more dies,each die contains an impression of the desired shape.Forging in which the material is fully constrained in the cavit...

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 comp...

Forging is a metal shaping process by application of compressive forces.According to the temperature at which is performed, forging is classified in “hot”,”warm” and “col...

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 ca...

Hot forging process 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 th...

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...

Both the cap and the ellipse head are used to seal the pipe. But there is a slight difference.
The cap is generally used for the end of the pipe, and the head is used for the upper and lower parts or ...

Marine pipe cap is a kind of pipe fitting which is welded on the pipe end or installed on the external thread of the pipe end to cover up the pipe. Marine cap is not only used in the manufacture of sh...

The cap is a pipe fitting installed on the external thread of the pipe end to cover the pipe. It is used for sealing the pipe, which has the same effect as the plug, but the cap can be directly screwe...

Insulated joints are also considered as an insulating material. They are special accessories for natural gas and chemical pipelines, which meet the requirements for sealing and electrical insulation o...

Insulated joints are usually produced in accordance with customer requirements, material, size, coating and inspection… For example,the following drawing requirements.
Monolithic Insulating Join...

Seamless steel pipe has hollow section, which is widely used as pipeline for fluid transportation, such as pipeline for oil, natural gas, gas, water and some solid materials. Compared with solid steel...

Wear resisting coating is a kind of coating with friction resistance  for steel pipes,pipe fittings and flanges. Its application in FPSO ships can effectively reduce the wear and tear of pipelines and...

3PE coating is a kind of anti-corrosive coating for pipe fittings, steel pipes(seamless steel pipe, spiral steel pipe and straight seam steel pipe) and flanges. 3PE anticorrosive coating refers to 3-l...

A polyurethane coating is a layer of polyurethane (a type of polymer) that is applied to the surface of material in order to protect it.It can protect the base material from corrosion,weathering,abras...

The welded steel pipe used in FPSO is made of steel plate or strip after being rolled and formed.
Straight welded pipe production process is simple, high production efficiency, low cost, rapid develop...

According to different production methods,the seamless steel pipe applied in FPSO(Floating Production Storage and Offloading) can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and...

With the continuous development of global economy, shipbuilding industry plays an increasingly important role in the process of economic construction. The demands of shipping trade and warship constru...
