FAQs of Boiler Safety Connection Group Holder

1. What is the surface treatment of the boiler safety connection group holder?

Plumberstar boiler safety connection group holder comes in nickel and chrome finishes. They’re made to meet different boiler room conditions and application needs.

Nickel plating uses an 8μm-thick nickel layer. It can effectively isolate air and water vapor. This reduces the risk of metal oxidation and corrosion in high-temperature, humid environments. It delivers stable and reliable protection. This process balances durability and cost control. It’s perfect for most residential and commercial construction projects.

Chrome plating has a mirror-like silver-white shine. It looks more high-end. It’s ideal for projects where equipment is installed and exposed, with high appearance requirements. It also has good wear resistance and corrosion resistance.

All surface-treated products must go through a salt spray test. We put them in a salt spray test chamber. It simulates the humid, dusty boiler room environment and high-corrosion coastal conditions. The test lasts at least 48 hours. We can provide the corresponding test reports.

Before leaving the factory, each product is individually inspected by 150 quality inspectors. These inspectors have an average of over 10 years of experience. They make sure there’s no missing plating, no pitting, no blistering, and no scratches. This ensures the delivered products meet the standards for appearance and process quality.

All surface treatment processes have passed quality verifications. Things like adhesion tests and salt spray tests. They comply with ASTM/EN standards. This guarantees reliable durability and consistent quality performance in different application scenarios.

2. How compatible is the boiler safety connection group holder?

We guarantee the compatibility of the boiler safety connection group holder from two aspects. This ensures the products are safe and reliable in real applications.

Thread Standard Compatibility

Pipe thread standards vary by region. We’ll confirm the interface specifications with you at the start of the project.

• European market: BSP thread. It can accurately match local common pressure gauges, exhaust valves, and safety valves.
• North American market: NPT thread. It meets local piping system connection specifications.

Interface Layout Compatibility

We can flexibly adjust the position and direction of interfaces based on your specific needs. We also support adding or removing interfaces. Just provide a simple sketch or explain your functional requirements. Our engineers can complete the structural design and include it in the production plan.

3. Do you offer component matching for the boiler safety connection group holder?

Yes, we offer component-matching services.

• When you order the boiler safety connection group holder, we’ll reach out to you during the order confirmation process to discuss your application and the required specifications.
• For part matching and selection support, you just need to provide the required features and key specifications. Plumberstar’s engineering team will select the best-matching, cost-effective components for you. We’ll also provide a complete part matching list within 24 hours.
• Based on your requirements, we can pre-assemble the entire support system. We’ll carry out system pressure tests and tightness tests on the assembled components. And we’ll issue corresponding test reports.
• All boiler safety connection group holders come with a 3-year warranty. If there’s a mismatch or quality problem, we’ll respond quickly. We’ll provide replacement services to make sure your project schedule isn’t affected.

In addition, we offer brand customization services. This includes laser engraving logos on brackets, customizing pressure gauge dial styles, and more. Help you strengthen brand recognition in your end market.

4. What tests does each boiler safety connection group holder get before shipment?

Every boiler safety connection group holder from the Plumberstar factory must pass four strict quality inspections. Only those that pass all of them can be shipped out.

1. Raw Material Chemical Composition Test: Before brass or stainless steel bars are put into production, we use a spectrometer to analyze their chemical composition. We focus on checking the content of key elements, such as lead and zinc. This avoids cracking and corrosion issues caused by abnormal material composition later on. It also ensures the raw materials meet corresponding international standards.
2. In-Process Size and Thread Inspection: During key machining processes, quality inspectors use professional measuring tools, such as calipers and go/no-go gauges. They check core dimensions—such as installation hole spacing, interface thread specifications, and bracket thickness. This ensures products strictly follow design drawing requirements. It also guarantees assembly compatibility and stability of boiler safety components.
3. 100% Air Tightness and Water Pressure Test: First, we seal all bracket interfaces. Then we inject compressed air or clean water from the main inlet. We pressurize it to 1.5 times the rated working pressure and hold it for at least 30 minutes. This test can effectively detect potential defects, such as tiny sand holes and cracks. It prevents leakage risks in actual use.
4. Batch Consistency Verification: Before shipment, we check each product’s batch number against its corresponding quality inspection records. We confirm that the same batch of products is consistent in process parameters, size accuracy, and performance. At the same time, we issue a complete inspection report. It’s delivered together with the goods to ensure quality traceability.

5. How are boiler safety connection group holders packaged for bulk shipping?

Our packaging process goes like this:

1. Each product gets independent protection. We wrap them in EPE pearl cotton bags or non-woven bags. For products with complex structures, we use custom blister trays or pearl cotton liners to fix them in place. This stops them from shaking around during transportation.
2. Then we put the wrapped products into corrugated inner boxes. We add cardboard partitions inside these boxes—no more product-to-product collisions.
3. Next, we pack multiple inner boxes into high-strength five-layer or seven-layer corrugated outer boxes. We lay a moisture-proof film inside the boxes before sealing them up. This handles the dampness that comes with marine shipping.
4. Finally, we stack all the outer boxes neatly on international-standard fumigation-free pallets. It makes overall handling and customs inspection way easier.

6. Do you offer ODM service for the boiler safety connection group holder?

Of course. Plumberstar is a professional valve manufacturer.

You need to come up with an idea. Our engineering team will communicate with you in depth. We’ll analyze the solution’s feasibility based on the actual use environment. We’ll also give you professional optimization suggestions.

After your requirements are confirmed, we’ll turn your ideas into standard CAD engineering drawings. Then we’ll send them to you for review.

Once the drawings are confirmed, we’ll make samples using CNC machining. We’ll run comprehensive tests on these samples. After testing, we’ll provide you with a detailed test report. When the samples are sent to you, you can also do your own installation and performance verification. This makes sure your requirements are fully met.

Only after you confirm the sample test results and sign off on them will we officially start mass production.

7. Does the boiler safety connection group holder support LCL?

Plumberstar’s boiler safety connection group holders are fully compatible with LCL transportation.

If your order quantity isn’t enough to fill a standard container, we can mix these holders with other pipes and valves from the same batch, heading to the same port. We can ship them by sea, air, or land flexibly. This helps you cut down logistics costs.

We provide full logistics tracking throughout the whole transportation process. We also support separate customs declarations and destination port allocation. This ensures goods arrive at your designated location safely and efficiently.
