What are Nickel Alloys Pipes

What are Nickel Alloys Pipes? Nickel alloy pipes are pipes made of nickel alloy with a hollow cross section and used as a material for transporting fluids, such as nickel alloy pipes for transporting petroleum, natural gas, coal gas, water and certain solid materials. Compared with solid steel such as round steel, nickel alloy steel pipe has light weight when the bending and torsional strength are the same. Nickel alloy steel pipe is an economical section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes. Automobile drive shafts, bicycle frames, and steel scaffolding […]

What is a casing pipe?

What is a casing pipe? Casing pipe is a type of steel pipe that is typically used to enclose and surround a carrier pipe, which is installed through the center of this pipe. Steel casing pipe is most often used in underground construction projects to encase or protect utility lines from being damaged. This pipe can be used when boring horizontally or directionally under roads, rivers, lakes, or railroads. In general, steel casing pipe is extremely durable and versatile, and therefore, it can be used in a variety of construction projects as well. Casing Pipe is available in a complete variety […]

How to Choose the raw material for fasteners

What are fasteners? A fastener (US English) or fastening (UK English) is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. Welding is an example of creating permanent joints. We mainly use a fastener for a non-permanent joint. What do we mean by a non-permanent joint? A joint that can be removed or dismantled without the destruction or damage of the joining components can be termed as a non-permanent joint. A welding joint or riveted joint can […]

How to choose valves in the industrial pipeline? (II)

Selection of valves Valves are generally selected according to factors such as characteristics of media, operating conditions and valve requirements. The major Chinese valve manufacturer can manufacture various types of valves according to the above standards to meet the needs of refining and chemical production. Commonly used valves are as follows: Gate valves The wedge disc of the gate valve is driven by the valve stem and moves up and down along the sealing surface of the valve seat to connect or cut off the fluid. The gate valve has small flow resistance and is easy to be opened and […]

Review and forecast of seamless pipe market in the first half of 2018

After the ups and downs of the price of 17 years, the seamless pipe market mentality in the first half of 18 years was more peaceful, and the overall price showed a rational correction in the shock. The profitability of the pipe factory has shrunk, and traders have been more difficult under the dual pressure of capital and demand. From the middle of the year to the middle of the year, the overall mood of the industry was slightly depressed. The market’s import and export data did not perform well. Many factors affected the market. We review the following aspects: […]

What are ERW steel pipes

What are ERW steel pipes? ERW steel pipes means Electric Resistance Welded Pipes. ERW steel pipes and tubes are used. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes. Manufacturing Process of ERW Pipe Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together […]

How to choose valves in the industrial pipeline? (I)

A valve is an important component of refining and chemical pipeline systems and plays an important role in petroleum processing.Valves are used to connect and cut off the medium, prevent the medium from flowing backwards, adjust the medium’s pressure and flow rate and distribute the medium. Selection of valves The selection of valves is mainly based on the trouble-free operation and low cost. Generally, the following principles should be considered. (1) Characteristics of the transported fluid Valves are used to control fluids, and the characteristics of fluids are diverse. There are fluids including gas, liquid and steam, and there are […]

How to get seamless steel pipes?

What are seamless steel pipes? Seamless steel pipes are long, hollow tubes that are used for a variety of purposes. Raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless steel pipe. Production Process of Seamless Steel Pipe According to manufacuring process of seamless pipe,seamless pipe can be divided into hot rolled seamless tube and cold drawn seamless tube. Process flow chart of cold drawn seamless steel pipe Cold drawn seamless steel tubes process: round tube → heating → perforation → Heading → annealing […]
