NACE MR0175 Pipe and Fittings Steel pipe and related fittings which are made from the NACE material (complied with NACE MR 0175 or ISO 15156 standard). We call them NACE pipe, or NACE pipe fittings. Therefore, these products are specially used in the oil a ...

How to select material Steel materials that selected or qualified using NACE MR0175/ISO 15156 are resistant to cracking in defined H2S-Containing environments in oil and gas production, but are not nesessarily immune under all service conditions. Consequen ...

Always in pipeline systems we met the material with NACE MR0175/ISO 15156 pipe or fittings, so do you really know what is the major differences between NACE carbon pipe and normal carbon steel pipe? And how is the cost for nace material? So today we are go ...

Welded steel pipe is a seam steel pipe. Its production is to bend the tube blank (steel plate and steel strip) into a required cross-sectional shape and size by various forming methods, and then use different welding methods to weld the seams. The process ...

Heat treatment is an important link in mechanical manufacturing. The quality of heat treatment is directly related to the internal quality and performance of products or parts.There are the matters need to attention in quality inspection of heat treatment. ...

After annealing, normalizing, quenching, tempering and surface modification heat treatment, the forging may produce thermal treatment distortion. The root cause of the distortion is the internal stress of the forging during heat treatment, that is, the int ...

Heat treatment, also called thermal treatment, is a method that put materials into troubles performing medium for heating, heat preservation and cooling. Also, it is a kind of technical process to control the performance of materials through changing the s ...

In last article,we learned what is 3PE coated steel pipe.Today let’s see advantages of 3PE coated pipe. Durable lifetime 3PE epoxy coated steel pipe have good stability and anti-aging performances under the normal work temperature and pressure condit ...

With the development of coating technique,more and more client require FBE coated pipes.What is the feature and types for FBE coated pipes? FBE coated pipe Features The advantage of the FBE coating pipe is convenient to spraying, no pollution, excellent re ...

3PE anti-corrosion coating is a kind of anticorrosive coating for pipeline products. 3PE anticorrosion has three layers of polyethylene coating (MAPEC), which is composed of epoxy powder (FBE), adhesive (AD) and polyethylene (PE). It is widely used in pipe ...

ERW steel pipe is the abbreviation of resistance welding. The welding methods of ERW pipe and submerged arc welded pipe are obviously different. Pressure welding without filler metal is adopted. The skin effect and proximity effect of high frequency curren ...

In tempering, a material is heated to below its critical temperature. This heating process increases ductility and toughness of a material. However, since ductility and strength are inversely related, tempering generally reduces strength. This loss of stre ...

Annealing is a process in which a metal is heated to a particular high temperature, held there for a period of between several hours and several days, and allowed to cool. In order for the annealing process to occur correctly, this cooling process must be ...

Hot rolling and cold rolling are both steel plate or profile forming processes, and they have a great influence on the structure and properties of steel. The rolling of steel is mainly hot rolling, and cold rolling is only used to produce small section ste ...

High frequency welding principle: With the skin effect of the high-frequency current, the high-frequency electric energy can be concentrated on the surface layer of the weldment, and the proximity effect can be used to control the position and range of the ...

Both hot forming and cold forming form metal into its final shape,but what’s the difference between hot forming and cold forming.We compare them in several ways. Run Speed & Quality With hot steel, it might take 50 rolls to thin a workpiece out, ...

Hot forming process is used very frequently for casting of industrial products and parts. In this process, heat is applied to soften the piece of metal. This metal or raw material is available in the form of sheet, bar, tube or wire. Then some form of pres ...

Typically it’s a process in which the metal sheet or strip stock is placed between rollers and then compressed and squeezed. The amount of strain generated determines the hardness of the finished product. There can be numerous types of cold rolling m ...

The continuous strengthening of stainless steel sheet materials is constantly developing to meet the actual needs. There are many ways to strengthen the stainless steel plate. The strengthening of stainless steel plate can reduce the thickness of the plate ...

There are many ways of anticorrosive treatment on stainless steel pipes. By improving the surface treatment methods and processes of stainless steel pipes, many practical applications can be improved.(What is the main classification of stainless steel pipe ...
