Press-fit Adjustable Stroke Fire Base

During the construction of fire sprinkler and fire hydrant pipeline networks, the traditional fixed base has many drawbacks such as inability to adjust height, difficulty in adapting to ground height differences, and the need for welding and flame ignition during installation. The fixed base cannot fit the uneven ground surface on site, making it difficult to make minor adjustments to the pipeline later; welding operations pose safety hazards due to open flames at the construction site, and the threaded connection is prone to interface leakage and loosening over a long period of pressure, affecting the safety of the entire fire protection system operation.

The Press-fit Adjustable Stroke Fire Base is made of high-load carbon steel, with the surface electroplated to form a uniform anti-corrosion protective layer, significantly extending the service life in outdoor and humid basement environments. The product integrates two core structures: standardized compression connection and continuous adjustable stroke. It does not require welding or tapping, and can be quickly fixed and sealed for the pipeline by using common tools; on-site, the support height and horizontal position can be freely adjusted to easily adapt to complex installation conditions such as uneven ground, narrow pipe shafts, and ceiling voids.

Technical parameters

Base material anti-corrosion and load-bearing structure advantages

1. High load-bearing carbon steel integrated molding

The Press-fit Adjustable Stroke Fire Base is made of high-quality thickened carbon steel through forging. The overall mechanical strength is high, capable of withstanding the self-weight of filled water fire pipes, additional loads from valves, and long-term pressure without deformation or bending, meeting the load requirements of fire support and hanger standards.

2. Electrostatic painting full coverage anti-corrosion treatment

The entire workpiece undergoes a complete electrostatic painting process, with uniform and fine paint film. The inner cavity and edge gap can be completely covered. Its salt spray resistance and rust prevention ability far exceed those of ordinary spraying processes. It is not prone to rust and corrosion in damp basements, underground garages, etc.

3. Integrated structure without weak connection points

The base support and compression connection parts are processed as a whole, without splicing weld seams, and will not break or crack under long-term water flow impact and slight vibration.

Core advantages of compression welding-free connection

1. No open flame operation throughout the process, avoiding fire hazards

Abandoning traditional welding and thread wrapping with raw material tape processes, no open flame is required at the construction site, eliminating the safety risk of welding sparks igniting surrounding building materials. Indoor decoration and sealed machine room construction can be carried out safely.

2. Standard tools for rapid assembly to enhance construction efficiency

Press-fit Adjustable Stroke Fire Base, combined with industry-standard compression tools, can complete pipeline connection. A single person can quickly complete the fixation and sealing, without the need for multiple people to cooperate in welding or threading, significantly reducing the construction time at each point, and batch fire protection projects can effectively reduce labor costs.

3. Compression bonding sealing eliminates pipeline leakage

After compression, the connection part between the pipe material and the base is tightly bonded, forming a permanent sealing structure. Under water pressure fluctuations and alternating cold and hot conditions, the sealing state is stable, and there will be no leakage or water seepage hazards, ensuring the sealing performance of the fire protection system.

Adjustable stroke offers flexible construction advantages

1. Highly adjustable on-site to accommodate height differences

With a unique adjustable stroke structure, during the construction process, the support height can be freely adjusted. This easily resolves the unevenness of the ground and floor base surfaces, eliminating the need for additional pad installation to raise the level. It simplifies the on-site construction steps.

2. Flexible adjustment of horizontal position to adapt to complex piping systems

The support point position can be slightly shifted for adjustment, suitable for restricted installation spaces such as ceiling voids, narrow pipe shafts, and densely installed equipment areas. Without changing the pipeline layout, stable support and positioning can be achieved.

3. No need to dismantle the base after completion for minor pipe adjustment

If the pipeline needs to be slightly offset or the elevation needs to be adjusted later, simply loosen the adjustment structure to re-calibrate the height and position. There is no need to remove the entire pipeline. This significantly reduces the maintenance and renovation workload.

Multi-scenario adaptive application scope

1. Civil building sprinkler pipe network support

Suitable for supporting the automatic sprinkler fire extinguishing system pipes in residential buildings, office buildings, and shopping malls. It can also be used for concealed ceilings and underground garages. It is compatible with the common civil fire protection construction standards.

2. Indoor and outdoor fire hydrant pipe installation

As a dedicated support base for fire hydrant vertical pipes and horizontal branch pipes, it meets the load-bearing requirements and has rust-proof performance suitable for long-term use in outdoor corridors and semi-open fire lanes.

3. Factory industrial fire protection network

Suitable for industrial fire pipe systems in factory workshops and storage warehouses. It can cope with humid, dusty, and slightly corrosive medium environments in the workshops, meeting the acceptance standards for industrial fire engineering.

Factory-wide quality control testing standards

1. Multi-dimensional sampling batch testing

Before each batch of Press-fit Adjustable Stroke Fire Base is shipped out, a full inspection is conducted, including load-bearing testing, compression connection sealingity water pressure testing, and electro-coating corrosion and salt spray verification as the three core testing procedures to screen out non-compliant products.

2. Complete production testing records are archived and retained

All data throughout the process from raw material entry verification, molding processing, surface coating, and final product testing are uniformly archived and saved to achieve full traceability of quality from raw material processing to product shipment.

3. Complete compliance qualification documents are provided for delivery

At the same time, material testing certificates, factory load and sealingity test reports, and product fire safety qualification documents can be provided to meet the dual requirements of domestic engineering supervision acceptance and overseas project customs clearance.

Installation and Usage Precautions

1. Requirements for foundation treatment during installation

The support points of the base should be set on the load-bearing structure of the building, and must not be fixed on areas with insufficient load-bearing capacity such as lightweight partitions or ceiling decorative panels; before installation, remove the debris and dust from the base surface and ensure that the base fits smoothly.

2. Specifications for carding operation

The carding operation must be completed using the matching standard carding tools; it is prohibited to directly strike the carding interface with a hammer; after the carding is completed, visually inspect the bonding position to confirm that the pipe material is not offset and there are no gaps at the interface.

3. Specifications for adjusting and locking operation

After adjusting the height and horizontal position of the base support to complete positioning, the adjusting and locking fastener must be tightened to prevent the base from sliding down or the support from shifting due to the self-weight load of the pipeline when the pipeline is filled with water.

4. Limitations on environmental use

In special chemical workshops that are exposed to strong acid and alkali corrosive media for a long time, auxiliary anti-corrosion protection materials must be provided simultaneously; the base cannot be used to support high-pressure special fluid pipelines with pressures exceeding the conventional water pressure in fire protection.

5. Key points for completion and acceptance inspection

After all the pipeline installation is completed, check the locking state of the base and the integrity of the carding seal point by point; during the water filling and pressure test of the entire pipeline, pay special attention to observing whether there is leakage or structural deformation at the support points of the base.
