DN1600X2000mm Medium-sized Composite Autoclave Sent to the U.S.

The Medium-sized composite autoclave (also called composite autoclave or carbon fiber autoclave) is a pressure vessel for curing resin-based composite products, providing it with necessary heat and pressure, and is widely used in high-tech fields such as aerospace, electronics, weapons, transportation, sports equipment, and new energy sources.

At the end of 2020, we TAIAN STRENGTH received an inquiry from a US customer, requiring medium-sized composite autoclave with a diameter of about 1600mm and a length of about 2000mm. Because it is an American customer, pressure vessel design and standards must be in accordance with ASME standards, and our company has had ASME certificates and manufacturing qualifications for 4 years, and has produced more than a dozen ASME products. We have rich experience in the production of composite autoclave for American standard products

According to the customer’s requirements, the number of vacuum paths of the autoclave has been adjusted from 8 at the beginning to 12. We use sampling and separation methods for customers to increase the efficiency and accuracy of vacuuming. Customers can adjust the number of vacuum ports according to the size and number of their own materials and composite products.

Regarding the working voltage and frequency of the autoclave, we can produce 380V, 440V according to customer requirements, or customize. During the period, I repeatedly confirmed the voltage with the customer, because this factor is also a major factor affecting the price of the equipment. On the one hand, ensure that after the equipment arrives at the site, the equipment does not fail to work normally due to voltage and frequency problems. On the other hand, it can also provide customers with a relatively reasonable price. In the end, the American customer gave a voltage of 440V, 50Hz.

The customer put forward the need the human interface in English, and our PLC control system uses the German Siemens brand touch screen system, which can not only control by one button, but also display the situation in the autoclave in real time.

After fully communicating with the customer, the parameters of the medium-sized composite autoclave are finally determined as the following:

DN1600X2000mm Medium-sized Composite Autoclave Parameters

Effective diameter：1600mm

Effective length：2000mm

Pressure Vessel Column Successfully Finished and Will Delivery soon

Everywhere whole of Taian city is full of vitality in the mid-spring season.March 21, 2021 is a happy day. The pressure vessel column project for one national oil company undertaken by Taian Strength Equipment Co., Ltd. was successfully completed and passed the acceptance of the third-party inspection company SGS project team. In the next few days, the ship carrying highly anticipated pressure vessel column will delivery and set sail to the other end of the continent.

On December 10, 2020, after a one-month comprehensive investigation,one national oil company finally selected Tai’an Strength Equipment Co., Ltd. as the general contractor of the pressure vessel column project. This project contains a total of 5 spherical storage tanks, which requires 120 welded pressure vessel column with an outer diameter of 1000 mm. Design standard ASME, required material is SA516Gr70N.Steel plate thickness is 30 mm, design service life is 15 years and manufacturing cycle is 4 months . Due to its huge storage capacity, it will have very high requirements for the supporting parts.The quality of the pressure vessel column will play a vital role in the stability of the entire spherical tank.

After the project was confirmed, our quality manager and quality engineer immediately set up a technical communication team with relevant personnel of a national oil company to fully meet the specific technical requirements. Based on the higher product quality requirements for Pressure vessel column, our company has selected Wugang, the best quality steel factory in China, as the raw material supplier for this project. After the preliminary technology requirements were determined, the engineers of the two parties immediately proceeded to confirm the relevant qualifications. Based on the requirements of pressure vessel column, the welding engineers of our company have formulated WPS, WPQ, JIC and other related operating procedures according to the operating requirements.In the early stage, after the preliminary review by the customer engineers, the relevant CWI personnel of our company immediately carried out the qualification certification work on the documents. The customer engineers were also quite satisfied with this.At the same time, our company immediately started to get in touch with SGS to comprehensively check the quality of this product. Considering that the pressure vessel column products require a lot of welding work, our workshop personnel have conducted a thorough study on the construction drawings. In order to ensure the smooth progress of this work, our company purchased a large number of roller racks. The purpose of purchasing the roller racks is to ensure the deformation of the welded plate and steel pipe due to stress after welding. None of the pressure vessel column welded after the use of the roller frame has any deformation problems. SGS inspectors also highly praised this part of our company’s work.

The period after the project confirmed also coincides with the Chinese Lunar New Year and the rebound of the epidemic in some provinces, which poses a great challenge to our production work. Taking into account the relatively tight manufacturing period of the entire project, our leaders immediately started to coordinate the work of various related personnel, make each work to the individual, and the responsibility to the individual. Through the efforts of all the company staff , the efforts paid off. After two and a half months of intense production, all the welding work of all pressure vessel column was completed half a month ahead of schedule. All dimensions have also been strictly inspected by the SGS project team, and all have met the customer’s requirements.The customer is also very satisfied with it. Due to the tight schedule of the entire project, our company also got in touch with the shipping company. All products will be loaded on vehicles in the near future and deliver to Tianjin Port so as to strive to catch up with the earliest ships. I hope this project can be an opportunity for our company to cooperate with a certain national oil company and open a closer cooperation relationship between the two parties in the future.

How to Avoid Composite Autoclave Machine Accidents?

Composite autoclave machine (also called carbon fiber autoclave) is a kind of pressure vessel equipment. Users should pay special attention to the safety of related pressure vessel operation during its use, except the safety of conventional equipment. The main manifestation is the explosion or explosion caused by the of hyperpressure inside the autoclave machine or leakage accidents, so it is necessary to formulate corresponding precautions in order to safely carry out the production work of autoclave machine curing. There are related autoclave machine explosions and leaks in the past. Today, we will briefly discuss how to avoid autoclave machine accidents.

1. The operator must strictly abide by the technological process and labor discipline, and operate in strictly accordance with the safety technical operating procedures. Not only the operators, but also the management personnel of the enterprise must understand the basic knowledge of autoclave machine, related laws and regulations. The operators of autoclave machine must be trained and certified. The safety interlock alarm device can not changed on the autoclave machine at will. It is necessary to purchase composite autoclave machine products with qualifications for designing and manufacturing autoclave machine .

2. Before production, the autoclave machine must be carefully inspected and the obstacles must be removed in the autoclave machine to make sure that the tank cover is fastened during each production, and the screws should be complete and intact. The auxiliary instruments, signals, pressure gauges, and safety valves of the equipment should be checked regularly. Lubricate mechanical bearings as required. It is strictly forbidden to continue working when the autoclave machine is leaking, the pressure gauges and the safety valve are malfunctioning, or other abnormal conditions. It will need strictly control the feeding amount, speed, sequence, temperature, pressure, etc., to prevent the temperature and pressure in the tank from rising sharply and over-temperature and differential pressure.

3. When the material enters into and exitsoutthe autoclave machine, the bridge rails should be laid flat and straight, the trolley should be pulled and steadily pushed over the rails. Rapid collisions are not allowed to prevent dumping and injury. After the working process of thermo-compression curing is completed, it is necessary to confirm that there is no residual pressure before opening the middle and inlet seals, otherwise it is strictly prohibited to open the tank. Tighten the nuts evenly when the tank seamed, and there should be no air leakage. The air intake should be slow and take attention to the reading of the pressure gauge, also pay attention to whether if the pressure gauge fails. During work, if there is a strong leak in pipelines, valves, instruments and tanks should close the valve immediately and open the exhaust valve, report for repair in time.

4. When people at work, you must concentrate and always pay attention to the operation of the equipment and the surrounding safety. When autoclave machine is working, the operator should patrol the side of the autoclave machine.It is forbidden to stand in front of the tank cover, behind the machine head and the joints of the tank cover. It will also need pay attention to the valve and pipe joints to prevent the high temperature and high pressure in the tank from rushing out and hurting people. It is not allowed to leave the post while working. When filling and unloading cans, you must cooperate closely with the operators and follow the safety operation regulations.

5. At the end of the work, you should turn off the power switch, check whether all buttons and handles are in the zero position. It must close all inlet valves of the autoclave machine and open the exhaust valve. Carefully make process records and handover records. Resting and drying clothes in the autoclave is prohibited. It is strictly forbidden to bake other items in an empty.

6. It should perform regular inspections to ensure the safe and effective use of autoclave machine, safety valves, pressure gauges, and quick-opening alarm devices. Prohibit flames, and ground them well to prevent static electricity.
