Our relentless pursuit of product quality and technological advancement ensures that we continuously strengthen our capabilities, enabling us to wholeheartedly deliver superior products and comprehensive solutions to our valued clients.

Tailoring Excellence: Design Innovation for Diverse Needs

At Center Enamel, we understand that off-the-shelf solutions often fall short when addressing the complexities of modern industrial processes. In response to the diverse and often intricate needs of containers operating under varying conditions, our approach is rooted in high-standard design work, driven by a commitment to crafting exclusive products meticulously tailored for each customer. Our engineering philosophy recognizes that optimal performance and safety are paramount, especially under challenging operational parameters.

During the design phase, we meticulously analyze the critical factors that dictate the structural integrity and material suitability of each vessel. Temperature and pressure are paramount considerations, forming the basis for the precise determination of the required thickness of the container material. Simultaneously, the chemical characteristics of the medium being contained, specifically its acid or alkaline properties, serve as the key determinant in our rigorous material selection process. This comprehensive approach ensures that every pressure vessel leaving our facilities is engineered to deliver excellent performance, unwavering safety, and long-term reliability, even when operating under the most complex working conditions.

Precision Manufacturing: The Foundation of Quality

The quality of a pressure vessel is intrinsically linked to the precision and care taken during its manufacturing. At Center Enamel's state-of-the-art production workshop, we leverage the power of automated CNC equipment for precise cutting and forming of vessel components. This advanced technology ensures unparalleled accuracy and consistency in every stage of production. Complementing this precision machinery is our suite of professional testing equipment, which plays a crucial role in our comprehensive quality control processes. This meticulous approach guarantees that our pressure vessel products consistently meet the high standards demanded by our diverse clientele across multiple fields.

Uncompromising Quality Assurance: Meeting Global Standards

Our commitment to quality extends far beyond the manufacturing floor. Center Enamel has established a strict and comprehensive system throughout the entire testing process to guarantee that the quality of our pressure vessel products not only meets but exceeds stringent domestic and international standards. Our multi-faceted testing regime includes:

Nondestructive Testing (NDT): We employ advanced nondestructive testing methods to meticulously examine the integrity of welded joints, a critical aspect of pressure vessel safety. For butt-welded joints, local radiographic or ultrasonic testing is conducted, covering a minimum of 10% of the length of each weld. Crucially, local NDT also encompasses T-joints, ensuring the structural soundness of these complex intersections. All nondestructive testing of welded joints is carried out in strict accordance with JB4730.2 and JB4730.3 standards. For radiographic testing, we adhere to a technical level of AB with a quality level not lower than Sichuan level. Our ultrasonic testing follows a technical level of B with a quality level not lower than Level II.

Final Testing Procedures: Following the manufacturing process, each container undergoes rigorous final testing tailored to its specific application and design requirements. This includes comprehensive water, hydraulic pressure, air pressure, air tightness, or kerosene leakage tests, as mandated by the engineering drawings. These tests serve as a final verification of the vessel's integrity and ability to safely contain the intended media under pressure.

The Pillars of Our Manufacturing Excellence:

Our dedication to producing leading-quality pressure vessels is underpinned by a robust manufacturing process built on several key pillars:

Strategic Material Selection: At Center Enamel, the journey to a superior pressure vessel begins with the careful selection of raw materials. We exclusively source steel from large, reputable domestic steel mills, ensuring that the strength, toughness, and hardness of our materials consistently surpass industry standards. This commitment to using high-grade steel translates directly into more durable and longer-lasting products for our customers.

Advanced Welding Expertise: Our welding process integrates cutting-edge equipment and refined techniques, executed by highly skilled and certified professionals. This combination results in high work efficiency, smooth and uniform welds with clear lines, and ultimately guarantees the structural integrity and overall quality of our pressure vessels.

Customized Spraying Solutions: Recognizing the diverse operating environments of our pressure vessels, our spraying process is tailored to meet specific customer needs and adhere to stringent industry standards. By applying appropriate anti-rust and corrosion-resistant coatings, we significantly enhance the performance and extend the service life of our products.

Precision Sandblasting: Surface preparation is crucial for the longevity and performance of coatings. Our large-scale sandblasting equipment and advanced sandblasting process ensure that the surface of each tank is uniformly flat and optimally prepared for subsequent treatments. This meticulous preparation also results in a clean and bright finish.

Rigorous Final Testing: As previously detailed, our professional testing equipment conducts stringent sealing and pressure tests on every pressure vessel before it leaves our facility. This final stage of verification is paramount in ensuring the safety and reliability of our products for our customers.

Serving a Diverse Spectrum of Industries:

The versatility and reliability of Center Enamel's pressure vessels and normal pressure equipment have made us a trusted partner across a wide range of critical industries:

Petrochemicals: Our normal pressure equipment is essential for the initial storage and blending of crude and light oils, while our atmospheric distillation towers facilitate the crucial separation of crude oil fractions. Our pressure vessels play a vital role in storing chemical media under specific pressures, enabling processes like catalytic cracking for high-quality oil production and hydrogenation refining for impurity removal. In aromatics extraction, our vessels aid in the separation and recovery of key components.

Biopharmaceuticals: In this demanding sector, our normal pressure equipment stores biological fermentation raw materials and common medicine waves. Our liquid preparation badgers ensure the precise dissolution and mixing of drug ingredients, while atmospheric pressure storage tanks facilitate material handling. Our pressure vessels are critical for fermentation processes, creating controlled environments for microbial synthesis, and for freeze-drying to preserve the integrity of sensitive pharmaceuticals. We also provide storage and control solutions for gases used in drug synthesis.

Food and Beverage: Our normal pressure equipment provides hygienic storage for raw materials like fruit purees and sugar solutions, while our mixing tanks ensure the accurate blending of beverage components. Pressure vessels are indispensable for sterilization processes, extending shelf life and maintaining the quality of food and beverages. We also provide solutions for storing and controlling carbon dioxide in carbonated beverage production and for high-pressure steaming of food products.

Environmental Protection: Our normal pressure equipment is utilized in sewage treatment plants for flow regulation and in waste gas absorption towers for purification. Our pressure vessels are crucial for anaerobic digestion in sewage treatment, facilitating biogas production, and for the safe storage and control of high-pressure gases in advanced industrial waste gas processing.
