In the production process of ERW steel pipe

In the production process of ERW steel pipe, how to ensure that the product quality meets the requirements of technical standards and the needs of customers? An analysis of the factors that affect the product quality during the production of steel pipes. According to the statistics of non-conforming products of Φ76mm high-frequency welded steel pipe unit in a certain month, it is believed that the factors that affect the quality of steel pipe products during the production process are raw materials, welding process, roll adjustment, roll material, equipment failure, production environment, and other reasons. aspect.

Raw materials accounted for 32 .44%, below will introduce the infect of material to ERW steel pipe. The influence of raw materials on the ERW steel pipes. The factors that affect the quality of raw materials are mainly the three aspects of the unstable mechanical properties of the steel strip, the surface defects of the steel strip and the large deviations in geometric dimensions. Therefore, we should focus on these three aspects. 1. The influence of the mechanical properties of steel strips on the quality of steel pipes. The common steel used for welded steel pipes is carbon. The main brands of structural steel are Q195, Q215, Q235 SPCC SS400 SPHC, etc. The high yield point and tensile strength of the steel strip will make it difficult to form the steel strip, especially when the pipe wall is thick, the material has a large rebound force, the steel pipe has a large deformation stress during the welding process, and the weld seam is prone to cracks.

When the tensile strength of the steel strip is greater than 635 MPa and the elongation is less than 10%, the weld seam is liable to crack during the welding process. When the tensile strength is lower than 30 MPa, the surface of the steel strip is easily wrinkled due to the soft material during the forming process. China Custom Smart Drying Rack Factory It can be seen that the mechanical properties of materials have a great influence on the quality of steel pipes, and the quality of steel pipes should be effectively controlled from the perspective of material strength.2) The influence of surface defects of steel plates on the quality of steel pipesCommon surface defects of steel strips include sickle bending, wave shape, longitudinal shear bite, etc. The sickle bending and wave shape usually appear during the rolling of cold-rolled strip, which is caused by improper reduction control. During the steel tube forming process, sickle-shaped bending and wave deformation will cause the steel plate to deflect or overturn, which may easily cause overlap welding of steel pipes and affect the quality of steel pipes. Edge banding of steel strips usually occurs on longitudinal shear bands, which are caused by blunt or sharp disc blades for longitudinal shear. Due to the bite of the edges of the steel strip, this makes the steel strip easy to crack and crack during the welding process, and affects the stability of the welding quality.

3) When the width of the steel strip is less than the allowable deviation, the influence of the geometrical dimensions of the steel strip on the quality of the steel pipe reduces the extrusion pressure during welding of the steel pipe, which makes the welding of the steel pipe unstable, cracks or openings appear; When the tolerance is allowed, the extrusion pressure during the welding of the steel pipe will increase, and sharp nozzles, welding defects such as lap welding or burrs will appear at the welding place of the steel pipe. Therefore, the fluctuation of the steel strip width not only affects the accuracy of the outer diameter of the steel pipe, but also seriously affects the surface quality of the steel pipe. Before welding, the surface quality and geometric dimensions of each coil shall be checked. If the quality of the steel strip does not meet the standard requirements, production shall not be carried out to avoid unnecessary losses.

But, human beings are supposed to be the smartest creatures on the planet. Or at least they are the most creative when it comes to building a home and then heating it, supplying it with water and then wood floor registers making it last for a hundred years or more. With all of your smarts and civilization, it may be wise for you to take a nod from the animals and rely on the energy of the sun.Solar power is one of the most enduring ways that humans have found to power their world and live separate from the animals among them. Creativity in the format of modern convenience is truly a human gift.

No animal on this planet has ever been able to create a home out of concrete or brick. And, although the three pigs is a very popular children's story, there is only a very small sliver of truth to the enduring message. A house made of sticks will never stand up to the harshest conditions that mother nature has to throw at it. And, never mind that of a predator. As humans, we have the difficult task of being responsible for the environment. Where will your water come from? Where will you sleep?

Where does your food come from? A solar water heater is one such way in which a human can truly bridge the gap between living in modern society and caring for the future of the planet. Humans must utilize their instinctive talents and use what is available if they want to survive as a species. In the green world that human beings have come to live in, it is not hard to see that we are in danger of damaging the planet beyond repair. It is becoming quite clear that human beings are also among the most susceptible and sensitive species on planet earth. Humans are much more unwilling to adapt to their immediate environmental changes. Everyone knows that humans love to be comfortable. It is not in most people's nature to seek out the uncomfortable life. Truly, a modern life is a life that is protected from the elements and affords great warmth and insulation from the natural world. It is possible to be comfortable and caring of the planet at the same time with enough effort.

There are several types of

There are several types of solar water heater systems: Passive vs. Active is one of the initial decisions to make prior to considering the 2-3 systems available in each category. A solar contractor is necessary to assist in choosing the system that is a perfect fit for each customer's individual needs.A solar water heater system is a cost effective alternative to the traditional natural gas or electric water heater most homes use. While the initial investment of a solar system is higher in cost, and the installation needs to be done by a professional (standard water heaters can be purchased at a home improvement store), these appliances can save 50-80% in utility costs.The Active vs. Passive question is one of the first decisions a homeowner will need to make.

Passive is less expensive, is more reliable and usually lasts longer; but it is less efficient than an Active system. An Active system is more expensive and the choice aluminum air vent grilles between a direct circulation vs. indirect circulation system will need to be discussed (especially important for locations that experience freezing temps.) with a contractor. But these systems have proven to be more efficient than a Passive one.When building a new home, a solar water heater system should be considered, so the cost of purchase and installation can be rolled into the mortgage payment. On average, this cost breaks down to $20 per month over a 30 year mortgage when added to the monthly payment, and with a Federal tax deduction for mortgage interest for a solar system, the cost reduces the payment by $5 per month.

There are several considerations to be noted before deciding if a solar water heater is a reasonable investment. How much water does the household use each month? Is the current water heater functioning optimally? The geographic location of the home & amount of exposure to the sun is a vital piece of information that will determine if solar is the way to go. And will a backup system be required for this home?A contractor can answer any of these questions prior to scheduling the work to be done on the home.

In addition to these points, an evaluation of the site is necessary to determine time, cost and solar resources in the area. Local codes, covenants and regulations will need to be investigated for each location, and then a budget can be set for the job.Solar or Green energy is the movement toward a self-sustaining household many people dream of for their home. Going off the grid is a goal many individuals long to achieve, especially when the rising cost of fuels is taken into consideration.
