Special-Shaped Stainless Steel Screws Parts

Product introduction

Stainless steel sprinkler heads are made of stainless steel materials and are terminal water outlet devices that convert water flow into specific shapes through the internal structure, such as mist, cone, fan, etc. Its core value lies in utilizing the excellent corrosion resistance and wear resistance properties of stainless steel to ensure long-term reliable operation in complex water conditions and chemical environments.

 

Product design and features

The design of the sprinkler head fully serves its functional needs and has distinctive features:

Corrosion-resistant core: The main body is generally made of 304 or 316L stainless steel. Because 316L contains molybdenum (Mo), it has better resistance to pitting corrosion in chloride-ion-containing environments such as chemical industry and desulfurization. Function-oriented design: Different internal flow channel designs realize different functions. For example, the spiral nozzle can produce a solid cone spray for gas cooling and dust removal; the nozzle of the emergency shower needs to produce a soft and high-flow water curtain for rapid flushing. Precision connection requirements: In order to ensure the stability of the entire sprinkler assembly under vibration and high pressure, the connection between its internal structure, brackets and pipelines often relies on specially customized special-shaped stainless steel screw parts. These non-standard fasteners can meet the dual requirements of special installation space and corrosion protection. Easy-to-maintain structure: Some designs are designed to prevent clogging, such as spiral nozzles, or use a removable filter structure to facilitate users to clean scale.

 

Materials and application areas

304 stainless steel: general-purpose austenitic stainless steel with good corrosion resistance. Widely used in food processing, general industrial humidification, agricultural irrigation, bathroom showers and other fields

316/316L stainless steel: Contains molybdenum, which makes it more corrosion-resistant (especially resistant to chloride ion corrosion). It is the first choice for harsh environments such as the chemical industry, flue gas desulfurization, seawater desalination, wastewater treatment, and fire extinguishing.

 

Quality control and certification system

Industry and safety certifications: WRAS certification, NSF/ANSI 61 & 372, ASME A112.18.1/CSA B125.1, ANSI Z358.1, production quality control: for internal key special-shaped stainless steel screw parts and other connectors, refer to ISO 9001 and other system controls to ensure that dimensional accuracy, materials and corrosion resistance are qualified.

 

Customized services

To meet specific project needs, specialist manufacturers often offer customization services:

Size and flow customization, material and performance customization, function and structure customization, logo and certification customization.

 

FAQ

Q: What key points need to be paid attention to when customizing a batch of industrial sprinkler heads with special interfaces?

A: It is necessary to clarify: the working environment and medium (chemical composition, temperature, pressure) to determine the grade of stainless steel (such as 304 or 316L). Performance parameters (flow rate, spray angle, coverage). Mechanical interface (thread specification, installation method), which may require customized non-standard mounting brackets and special-shaped stainless steel screw parts. Certification requirements (if any).

 

Q: What is the difference between 304 and 316 stainless steel sprinkler heads? How do I choose?

A: The choice depends on the corrosive intensity of the use environment:

304 stainless steel: universal type with good corrosion resistance. Suitable for most common environments, such as home bathrooms, general industrial humidification, agricultural irrigation, urban tap water systems, etc.

316 stainless steel: With the addition of molybdenum (Mo) element, its resistance to chloride ion pitting corrosion and crevice corrosion is significantly enhanced.

 

Q: What are the main advantages of stainless steel sprinklers? Why choose stainless steel instead of plastic or copper?

A: The core advantages of stainless steel sprinkler heads are their excellent durability, safety and wide adaptability, corrosion resistance, strength and durability, hygiene and safety, and economy. Although the initial cost may be higher than that of plastic, its ultra-long maintenance-free life reduces replacement and repair costs throughout the life cycle.
