In summary, flange suppliers need to have production licenses, quality management system certification certificates, tax registration certificates and other qualifications.

Hot extrusion billet of seamless steel pipe can be forged billet, rolled billet, slab, billet centrifugal casting and so on.

for the design and use of the elastic modulus of carbon steel pipelines, it is necessary to calculate according to specific stress conditions and consider the influence of the manufacturing process

The curvature of mild steel tube will also affect the resistance coefficient. The greater the curvature, the greater the resistance coefficient.

Black steel pipes are composed of carbon and iron, and have certain strength and corrosion resistance.

In short, the manufacturing process of black steel pipes includes multiple steps such as forging, hot rolling, cold drawing, cold rolling, and welding.

Especially in humid environments, the corrosion problem of black steel pipes is particularly prominent. Therefore, anti-corrosion treatment is very necessary.

piral welded pipe for water supply pipeline project is an indispensable and important part of modern urban water supply system.

Commonly used weld hardness testing methods include Rockwell hardness, Brinell hardness, Vickers hardness and rock Rockwell hardness.

The right set of tubes and tack welding is on ensuring the quality of the welding, the back of a good weld is an important factor.

ERW is a general term for resistance welded steel pipes.

Stainless steel seamless pipe manufacturing process

Although the thermal conductivity of seamless steel pipe is smaller than other materials, it is better than other materials in specific application scenarios and is a cost-effective material.

In summary, Q500C seamless steel pipe, as a high-quality seamless steel pipe, has wide application prospects and market demand.

Pipeline Construction Construction of pipelines transporting petroleum products, natural gas and solid slurries. Including pipeline engineering, station warehouse engineering and pipeline ancillary engineering.

Hot-rolled seamless pipes are compared to cold-drawn seamless pipes. Cold rolling is rolling below the crystallization temperature, and hot rolling is rolling above the recrystallization temperature.

Insulated spiral steel pipe is to insulate spiral steel pipe (SSAW pipe). The most important method of insulation is polyurethane insulated spiral pipe.

Some seamless pipes require shrinking and flaring to produce products. The shrinking and flaring of seamless steel pipes is a forming process that shrinks and expands the mouth of a preformed steel pipe through a shrinking and flaring die.

Spiral steel pipe (SSAW pipe) is a welded steel pipe made of strip steel coil as raw material, extruded at room temperature, and welded by automatic double-wire double-sided submerged arc welding process.

The Advantages of Using ERW Pipes in the Oil and Gas Industry One of the main advantages of using ERW pipes in the oil and gas industry is their strength.

What is the standard of seamless steel pipe? Mainly used for general structure and mechanical structure.

Preheating before welding and heat treatment after welding

Long steel products such as seamless pipes and welded pipes are often bent or distorted due to external forces, temperature changes, internal forces, etc.

Anti-corrosion steel pipes refer to steel pipes treated with anti-corrosion technology, which can effectively prevent or slow down corrosion caused by chemical or electrochemical reactions during transportation and use.

Normalizing is to heat steel pipes (such as seamless pipes and welded steel pipes) to 30 to 50 degrees above Ac3 or Accm, and then cool them at a slightly higher cooling rate than annealing after insulation.

Steel pipe piles and steel sheet piles are both structural members used in construction projects, but they differ in shape, use and installation methods.

The straight seam welded pipe production line is a process in which the steel plate to be welded is heated or pressurized, or both are used, with or without filling material

What is cold treatment of stainless steel pipes? Both stainless steel seamless steel pipes and stainless steel welded steel pipes can be cold processed - cold rolled and cold drawn to meet higher requirements for cold processed products.

Oil well pipes (including OCTG casing), also known as special oil pipes, are steel pipes specially used for oil and natural gas extraction. Most of them are seamless pipes, but welded pipes also account for a considerable proportion.

The site or warehouse for steel storage should be selected in a clean and well-drained place, away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed on the site to keep the steel clean
