3. Product Overview
3.1 Custom Pipe Fittings
Our pipe fittings include:
- Tees, elbows, reducers, couplings, and flanges
- Material choices: iron (carbon steel) and stainless steel
- Applications: hydraulic systems, chemical processing, oil & gas pipelines, and OEM machinery
Why choose custom fittings? Standard parts may not fit every system’s specifications. Our custom solutions allow for:
- Precise dimensions and threading
- Tailored pressure ratings
- Optimized surface finishes for corrosion resistance
- Special tolerances for industrial safety
3.2 Hex Socket Plugs
Hex socket plugs are critical for sealing, assembly, and maintenance of industrial systems. We provide:
- Standard and custom sizes
- Material options: iron and corrosion-resistant stainless steel
- Applications: pipeline sealing, high-pressure systems, and industrial machinery
Advantages include:
- Precision fit ensuring leak-free connections
- Durability in high-pressure or corrosive environments
- Long-term reliability, reducing maintenance costs
4. Customization Process
Our workflow ensures each component meets client specifications, from initial inquiry to delivery:
| Step | Description |
|---|---|
| 1. Enquiry | Customer send drawing to us , we check the technical drawing and confirm if we could satisfy the demand. |
| 2. Material study | We will switch from overseas to domestic material grade, then ask for the quantity. |
| 3. Quantity | Based on the quantity and drawing , we will give the best way to choose blank . Economy design is more easy to cath order from customers. |
| 4. Approved price | Customer accept price , for custom pipe fitting , must place a sample order for test customer quality demand , customer also want to test pipe fitting manufacuturer production power . |
| 5. Quality Inspection | Material inspection ,Dimensional checks, pressure testing, surface inspection, approve the sample order |
| 6.batch production | After approve the sample order , then customer will finally place small batch order , factory and customer will start big cooperation then quality is keep steady and good . |
This step-by-step process ensures customized, high-quality industrial components suitable for demanding applications.
5. Practical Case Study: Hex Socket Plug Production
Let’s look at a real-world example illustrating how we approach industrial decision-making.
Project Details:
- Product: Hex socket plug
- Drawing Specifications: Inner hex 0.25 inch, small size
- Quantity: 5,000 pieces
- Thread: PTF (tapered thread requiring tight seal)
Industrial Challenge:
- Based on drawing and size, the plug would ideally be produced using cold heading (cold forging). Cold heading ensures strength and excellent surface finish.
- However, the order quantity (5,000 pieces) was too low to make cold heading cost-effective. Additionally, the small internal hex made cold heading difficult to guarantee precision.
Decision-Making:
- Abandon Cold Heading: For this small batch, cold heading is not economical and may risk quality.
- Optimal Production Method:
- Punching the blank: Start with drilled holes in the raw material.
- Forming the hex socket: Use a press to stamp the internal hex shape accurately.
- Threading Consideration:
- PTF threads are tapered and require precise hard sealing.
- Rolling threads is the most economical and practical option for this batch.
- Requires experienced technicians to ensure the taper and sealing meet industrial standards.
Outcome:
- Produced 5,000 pieces with accurate internal hex and fully sealed PTF threads.
- Maintained tight tolerances, leak-free assembly, and minimized cost.
- Delivered on time to the client in Taizhou, China, ready for industrial integration.
| Parameter | Cold Heading | Punch + Press + Roll |
|---|---|---|
| Batch Size | Not cost-effective | Economical for 5,000 pcs |
| Hex Accuracy | Hard to guarantee | High precision |
| Thread Method | Integrated | Rolling threads (experienced operators required) |
| Cost | High | Optimal |
| Time | Longer setup | Faster for small batch |
This case illustrates how industrial expertise guides process selection, balancing cost, precision, and material properties.
