The quality of P235GH steel pipe shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of p235gh steel pipe buyer, such as packaging, delivery time, etc.. On the basis of the quality of p235gh steel pipe in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of p235gh steel pipe and certain performance limit of p235gh steel pipe, etc.

Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. p235gh steel pipe, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.

The hot rolling method is to heat the p235gh steel pipe steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of p235gh steel pipe rolling process is usually called semi-finished product production, also called blank production.

It is a modern high-tech professional enterprise integrating scientific research, p235gh steel pipe production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as p235gh steel pipe process technology development, technology transfer and related technical consulting and technical services.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
