Tube sheet are usually made of a round flat plate with holes drilled into the plate to accommodate tubes in the exact location and pattern relative to each other. The tube sheet is used to support and isolate the tubes in the Shell And Tube Heat Exchanger.
A tube sheet is a plate used to support a tube in a shell and tube heat exchanger. The tubes are aligned in a parallel manner and are supported and held in place by the tube plate. A tube sheet is a round plate with holes in it so that the tube can fit through the opening. Tubes are usually made of round, flat metal sheets. Drill holes for pipe ends in precise locations and patterns relative to each other. The tube plate is made of the same range of materials as the pipe.
These are usually made of mild steel and vary in thickness according to fluid pressure. Depending on the final application (petrochemical, nuclear, oil and gas, etc.), the tubes can be clad in stainless steel or other superalloys, or even made entirely of stainless steel or superalloys.

The production scale of one-quarter and three-quarter enterprises has been reduced to a total of more than 20 small enterprises. In the first half of this year, a total of 2.5602 million diesel engines were produced, which was a decrease of 255,400 units over the same period, a decrease of 9.07%. Among the aggregated companies, only 27% of the diesel engines showed a growth trend, the proportion of growth companies fell by 8 percentage points from the first quarter, and nearly three-quarters of the company's production declined in different degrees.
In the first half of the year, among the companies in Xiaochai, which had a better growth in diesel engine production, Shandong Laidong, which saw an increase of 26.66% in output in the first half of the year, increased production by 41.400 units, followed by Jiangsu Changfa, which had an increase of 29.02% in output and increased production by 61,400 units. In Fujian Lijia and Zhejiang Shangyu, output rose by 8.1% and 8% respectively. In the first half of the year, the output of enterprises such as Changchai, Wujin, Yangdong, Weichai, and Jintan, which were among the top few companies in the industry, declined at different levels.
Second, two-thirds of the company's sales reappeared in a weak state In the first half of the year, total sales of diesel engines totaled 2.6362 million units, a year-on-year decrease of 6.85% and a decrease of 193,800 units. From the perspective of enterprises, the sales volume in the first half of the year accounted for 32% of the growth rate. The rising proportion decreased by 4 percentage points from the first quarter, and sales of two-thirds or more of the companies decreased in different degrees.
In the first half of the year, companies with better sales growth: Weichai increased 45%, increased 39,800 units; Laiwu increased 32.93%, increased 47,800 units; Sales volume increased by 15% with an increase of 26,100 units.
Third, most of the products are declining, and a few models have a market. According to the incomplete statistics on the sales of different models of more than 20 households, the sales of single-cylinder diesel engines of all grades have basically declined in the first half of the year, and some of the sales have grown in the first quarter. Due to the weakening of the pace in the second quarter, the small horsepower diesel engine also showed a downward trend in the first half of the year. According to the summary, the sales of small-horsepower diesel engines with 60-70mm bores in the first half of the year were 112,300 units, a year-on-year decrease of 5.76%, a reduction of 11,100 units; sales of boreholes of 80-85mm were 149,000 units, a year-on-year decrease of 6.63%, and a reduction of 0.89 million units. 195 models sold 70,100 units, a year-on-year decrease of 38.84%, a decrease of 44,600 units; 1100-1115 models sold 1,110,600 units, a year-on-year decrease of 25.49% and a reduction of 380,000 units.
In the first half of the year, the sales of major grades of single-cylinder diesel engines all reflected declines. This is not a good sign. From the external environment, the decline in sales was mainly affected by the lack of demand and the decline in farmers’ purchasing power. However, from another point of view, the major varieties have almost all declined. This is a rare phenomenon. Does this mean that the products have structural surpluses or that some companies have blindly followed the trend due to the market’s promising products in the previous period, resulting in new ones? What is the imbalance between supply and demand? This anomaly deserves deep thinking from the industry.
In the first half of the year, a total of 171,100 units of multi-cylinder machines were sold, an increase of 7.6% year-on-year.
4. Exports showed double-digit growth, but the export delivery value fell in the first half of the year. The company's exports of diesel engines totaled 347,500 units, an increase of 59,600 units over the same period, an increase of 20.7%, and the export growth rate in the first half of the year rose by 9.7. The percentage point indicates that the situation of Xiaochai exports in the second quarter was better than the first quarter. In the first half of the year, the delivery value of Xiaochai's exports was 442 million yuan, a year-on-year decrease of 3.52%. The physical indicators and value indicators reversed, and there were changes in the product structure. However, more influencing factors were price declines.
From the perspective of enterprises that have export business, 57% of the companies’ exports have increased in different degrees, and 43% of the companies’ exports have declined. Among them, the enterprises with better export growth are: Shandong Laiyun's export volume is 41 800 units, an increase of 92.31%, an increase of 20,100 units; Shandong Juling exports 132,000 units, and Ningbo Sanhuan exports 26,900 units, an increase of 68.3%. Increment of 10,900 units; Danyang exports 0.43 million units, an increase of 5.5 times; Jiangsu Yangdong exports increased by 40.2%, an increase of 0.14 million.
V. The sharp decline in profits, the decline in the quality of economic operations is affected by the dual impact of the decline in the scale of production and sales, and the continuing low prices. As a result, the sales income of aggregated companies has declined, and profits have fallen substantially. The economic efficiency of Xiaochai industry has continued to decline.
In the first half of the year, total sales revenue of the consolidated enterprises was 4.469 billion yuan, a year-on-year decrease of 10% and a reduction of 496 million yuan. From the perspective of enterprises, 64% of the manufacturers' sales revenue decreased, accounting for 36% of the company's sales revenue growth, among which the better-rising companies had Fujian Lijia growth of 24%, an increase of RMB 13 million; Jiangsu Changfa increased by 17.6%, increased revenue. RMB 0.5 billion; Shandong Laiwu’s growth was 16.35%, with an increase of RMB 0.68 billion.
In the first half of the year, the company’s loss-making face was 27.3%, up 4.6 percentage points over the same period. Enterprises achieved a total profit of 140 million yuan, a year-on-year decrease of 34.82%, and a decline in profit was 24.8 percentage points higher than sales revenue. The significant decline in profits was due to the decline in the scale of production and sales on the one hand, and the continuous price wars on the other. The data from various companies showed that the ex-factory prices of almost all manufacturers in the first half of the year showed a downward trend, ranging from 2% to 5%, and more than 10%. The continuous escalation of price competition has led to a decline in the profits of most enterprises, which has affected the profit and taxation rate of corporate funds, the profit margin of cost expenses and the profit rate of sales revenue by 0.69, 1.24 and 1.2 percentage points respectively from the same period.
VI. Enlightenment of star enterprises In the first half of the year, although about 70% of the manufacturers’ production and sales volume declined, there are still a few big players and successes supporting the development of the industry. Among them, there are more outstanding players, giants, and regular players. And other companies.
In the first half of this year, Shandong Laidong’s adverse environmental impacts, including the improvement of marketing management and internal reforms, resulted in total aggregate output, output value, exports, income, profits, etc., and major economic benefits. Compared with the same period of time, the index production shows a relatively large increase. This growth contrasts strongly with the downward trend of the industry, indicating that the company has achieved remarkable results in the first half of the year, and its uniqueness, successful experience and practices in its operations. It is worth learning and learning from companies in the industry.
Shandong Juling’s export performance in the first half of the year was very significant. The export proportion of Xiaochai’s products was as high as 65.9%, not only a 25 percentage point increase over the same period, but also accounted for 38% of the total export volume of the aggregated companies, ie one-fourth The company occupies a third of its export share. Giant Ling products have such a high export share in the first half of the year, which is amazing and difficult, and it is a role model and role model for Xiaochai companies. Especially in the current weak domestic market, it is wise to shift the marketing focus to the international market as much as possible and try to explore the marketing strategies of the international market. JuLing's successful experience in developing the international market is indeed worthy of deep thinking and learning by the industry. .
In the first half of the year, Jiangsu Changfa's total production and sales volume of diesel engines exceeded 270,000 units, an increase of 29% and 30.8% year-on-year respectively, and the scale of diesel engine production and sales ranked third in the industry, a rise from the same period. Jiangsu Changfa has overtaken many state-owned large and medium-sized enterprises in a few short years, and continued to maintain a relatively rapid growth in production and sales in the first half of the year. This extraordinary growth rate, apart from With the flexible private mechanism and strict management as the backing, it is inseparable from the “short, flat, fast†and hard innovation in product development. Therefore, efforts to develop marketable products and accelerate the pace of new product development is half the company's success.
In the third quarter, there will be no significant improvement in demand in Xiaochai, and the competition among enterprises will become more intense. Therefore, it will face a more severe market situation. First, Xiaochai companies must have new developments and actions in technological innovation and product development. Adjust product structure, develop marketable products, improve product quality to open up markets and win customers. The second is to make great efforts to reduce costs and strengthen management, improve internal strength, and enhance competitive strength. The third is to take the path of asset restructuring and seek new and better ways to survive and develop. (Mechatronics)
Analysis of Production and Sales of Small Diesel Engine Enterprises in the First Half of the Year
In the second quarter of this year, although the single-cylinder Xiaochai market recovered and improved somewhat from the first quarter, due to various factors such as the limited production of the Xiaochun crops and the overall lack of demand in the agricultural machinery market, the Xiaochai market was still in a relatively weak state, resulting in the majority. The scale of production and sales of enterprises has declined, production capacity has been partially released, and the economic benefits are in a dilemma of continuous decline. According to the statistical analysis of some key Xiaochai companies, the operation of smaller industries in the first half of the year has the following characteristics:
