Explore our industrial-grade components, manufactured to strict global standards ensuring anti-corrosive reliability and constant-pressure seal integrity.
In contemporary fluid management, thermal fluctuations present a recurring challenge to traditional fastening technologies. Spring Action Hose Clamps (specifically constant-tension clamps conforming to standards like DIN 3021) are designed to provide a continuous radial tensioning force, compensating directly for the expansion and contraction of elastomers and thermal hoses.
As global automotive manufacturers pivot to Electric Vehicle (EV) platforms and complex Battery Thermal Management Systems (BTMS), the requirement for leak-proof connections under severe temperature fluctuations has expanded. Without a constant-tension spring mechanism, rigid fasteners are susceptible to "cold leaks" during thermal cycles.
From industrial HVAC loops in Germany to heavy transportation networks across the United States, spring-loaded systems ensure system reliability, prevent catastrophic pressure drops, and extend the functional lifespan of rubber and silicone fluid couplings.
Innovating connection technology since 2002. Headquartered in the strategic global transportation hub of Tianjin, China.
Mika (Tianjin) Pipeline Technology Co., Ltd. (originally established as Tianjin Jinchaoyang Hose Clamp Co., Ltd.) is a manufacturer dedicated to reliable, non-leakage seal technologies. Under the guidance of our founder, Mr. Zhang Di, who has nearly 15 years of technical expertise, the company has grown into a major supplier for domestic and international OEMs.
We hold a series of independent design patents and utility model patents. Our manufacturing operations utilize advanced precision molds, standardized processes, and quality testing equipment to deliver consistent clamp profiles that maintain uniform radial tension across temperature shifts.
Our strategic supply footprint features three primary production sites across China, facilitating fast deliveries and regional manufacturing support:
A history of scaling production capability, implementing automated processes, and obtaining certifications to support global industry standards.
Establishment: Jinchaoyang Mould Company was established, laying the foundation for our tooling design and molding capabilities.
Strategic Shift: Officially transitioned into a production-oriented enterprise focused on pipeline connection technologies.
OEM Recognition & Exports: Secured partnerships with domestic automotive companies (including GM Wuling, China FAW, BYD, and Changan). Acquired independent export rights in 2018.
Market Expansion & Automation: Expanded services to Europe, the United States, and the Middle East. Reinvested 20% of sales into automated manufacturing to increase production output. Officially renamed to Mika (Tianjin) Pipeline Technology Co., Ltd. on July 1, 2020.
Quality Certifications: Attained national high-tech enterprise recognition and obtained the IATF 16949:2016 automotive quality management system certification.
Multi-Base Operations: Opened Hebei production base in 2023 and Chongqing production base in 2024, scaling capacity to serve global supply chains.
Important considerations for raw material selection, metallurgical performance, and structural configuration in constant-tension applications.
Magnetism is not a reliable metric for evaluating stainless steel quality (201, 301, 304, 316). Cold-working is required to reach the tensile strength and hardness levels necessary for functional clamping pressure.
This cold-rolling process modifies the crystal structure of the alloy, creating a localized magnetic signature. The resulting magnetism indicates that the material has undergone appropriate hardening to function under load.
The galvanized coating on carbon steel screws serves two roles: corrosion protection and thread lubrication. For DIN3017 configurations, zinc electroplating provides a uniform surface that reduces frictional resistance.
If non-plated screws are required, wax-based compounds must be applied as a lubricant. However, prolonged storage, exposure to elevated transport temperatures, or harsh service environments can degrade wax coatings, reducing the tightening torque transmission.
T-bolt clamps equipped with helper springs are commonly used in charge air (CAC) and heavy vehicle coolant systems. The spring handles thermal expansion and contraction in the joint.
During installation, the spring must not be fully compressed (coils bound). A fully compressed spring behaves as a solid spacer, losing its ability to absorb thermal expansion and leading to excessive localized hose pressure.
Operational standards, manufacturing principles, and employee alignment that sustain our pipeline connection quality.
"Not designing unqualified products, not manufacturing unqualified products, not accepting unqualified products, and not transferring unqualified products." We implement standard process testing for incoming materials, checking hardness, tensile strength, and dimension parameters.
Our operational training framework is based on: Systematization (training throughout the career path), Institutionalization (routine training processes), and Diversification (matching trainees with specialized material training).
We practice craftsmanship in our execution, emphasizing objective, pragmatic cooperation between teams. We use precision tooling and modern testing equipment to maintain product quality standardization.
Mika products are used across critical pipeline connection sectors worldwide, ensuring leak-free performance under variable environments.

Technical guidance and sourcing information for industrial buyers.
Constant-tension clamps expand and contract dynamically in response to thermal cycles. Standard worm gear clamps apply a static radial force; during temperature drops, the hose material shrinks, which can result in cold leaks. Spring action clamps maintain constant pressure to prevent this issue.
Austenitic stainless steels (like 304 and 316) are naturally non-magnetic. However, during the manufacturing process, the steel must be cold-rolled to reach the tensile strength and hardness levels required for high-tension clamps. This process deforms the crystal lattice, causing the material to exhibit moderate magnetism.
Standard lead times range from 30 to 45 days, depending on the required material specifications (W1 to W5) and configuration. Having our tooling centers at our three production bases (Tianjin, Hebei, Chongqing) allows us to shorten pre-production tooling adjustment phases.
