A threaded stainless steel elbow is the core fitting for changing the direction of the pipeline in a pipeline system. Its core purpose is to accurately connect two sections of the same specification pipeline through threads. This elbow is suitable for all kinds of stainless steel pipeline systems that need to be turned to ensure the sealing and smoothness of the pipeline turning.
It’s a chrome-plated straight joint, which is the core fitting for connecting two sections of pipes of the same specification in a pipeline system. It is suitable for water, gas, and other conventional media. Its core use is to extend the pipeline or repair a broken one, allowing the fluid to pass smoothly and adapt to the indoor humid environment for a long time. The use of thread or sleeve connections enables installation without complex tools, and manual tightening can be completed.

1. Can you provide a material traceability report for the elbow?
Special Material Customization
For special material products, we only use raw materials that meet international standards.
This includes materials such as Hastelloy C276 (ASTM B575) and Monel 400 (ASTM B164). All raw materials come with official mill certificates from the material supplier. These certificates clearly show the heat number, chemical composition, and mechanical properties, so the material source is fully transparent and verifiable.
Full Traceability Documentation
Each customized elbow is supplied with a material traceability report.
The report records the full process, from raw material purchase to finished product manufacturing, with clear batch numbers at every step.
All information can be traced back to the exact material batch and supplier.
This traceability system follows the same standard used for Plumberstar special material valves, ensuring consistency across products and making it easier for customers to manage quality control and audits.
2. What stainless steel elbows do you offer?
Plumberstar Manufacturer
As a professional valve factory focused on foreign trade, Plumberstar designs its stainless steel elbows specifically to match valve systems. We offer a wide range of materials, including 304, 316, 316L, duplex steel 2205, and 904L, to suit different valve types and working conditions.
Material selection by application
304 stainless steel
Used with standard valves such as gate valves and ball valves.
Suitable for water, air, and other neutral media in municipal projects and general industrial pipelines.
316 / 316L stainless steel
Designed for corrosion-resistant valves, including chemical ball valves and globe valves.
Commonly used in chemical plants, marine environments, and high-humidity areas.
316L offers better chloride resistance and welding performance, making it ideal for welded valve–pipe connections.
904L stainless steel
Used for extreme media valves, especially in strong acid environments.
Suitable for sulfuric acid systems and seawater desalination, where standard stainless steel cannot perform reliably.
Free matching solution
Customers only need to provide the valve model, medium type, working temperature, and pressure.
Plumberstar will offer a free “valve + elbow” matching solution, ensuring full compatibility, safe operation, and long service life.
3. What is the difference between seamless and welded elbows?
From Saliran Group
Seamless Elbow
Seamless elbows have no weld seam, which gives them higher overall strength.
They can withstand pressures of up to 42 MPa, making them suitable for high-pressure valves, such as API oil and gas valves. They are commonly used in high-pressure pipeline systems, where the valve and pipeline share the same pressure load. Because there is no weld, the risk of leakage is greatly reduced.
Welded Elbow
Welded elbows offer a clear cost advantage, especially for large-diameter pipelines.
They are suitable for DN500 and above and for medium- and low-pressure applications, such as water supply and drainage systems, and standard chemical valves.
They support both welded and flanged connections and are fully compatible with Plumberstar valve connection standards.
4. What is the stainless steel elbow pipe quality control standard?
As an experienced foreign trade factory, Plumberstar follows international export quality standards across the entire production process. Quality control is applied at every key stage to ensure stable performance and smooth customs clearance.
Raw Material Inspection
All raw materials are tested before production. This includes spectrometer chemical composition analysis, mechanical property testing, and material certificates.
Each batch is matched with a corresponding valve material report, ensuring full material consistency.
Forming Process Inspection
During forming, we check dimensional accuracy, angle tolerance, and wall thickness uniformity.
All parameters are strictly controlled to ensure perfect compatibility with valve installation dimensions.
Welding Quality Inspection (for Welded Elbows)
For welded elbows, X-ray testing and ultrasonic inspection are carried out.
This prevents hidden welding defects and ensures sealing performance meets the same standards as the valves.
Finished Product Inspection
Final inspection covers surface quality and pressure testing.
Each shipment is supplied with a complete quality control report in both Chinese and English, making customs clearance easier.
5. What information is required when customizing the elbow pipe?
To match Plumberstar valve customization, three key types of information are required. These details help us ensure full compatibility between the valve and the elbow.
Basic Parameters
We offer custom elbow specs. You can obtain non-standard angles, such as 25° and 75°. Unconventional calibers such as DN1250 are available too. Special wall thickness grades, such as SCH120, are also on the list. We can even match the elbows with specific valves. Just tell us if you need them paired with designated products like Plumberstar DN800 gate valves.
Connection Mode
Please specify the connection type between the elbow and the valve. If a flange is required, the flange standard must be consistent with the valve.
Special Marking Requests: Please let us know if you require special markings on the elbows. You can choose laser etching, such as valve matching numbers or your project codes. This small detail goes a long way. It makes sure elbows pair up right with valves during on-site installation. It also cuts down on installation mistakes.
6. Can the customer come to the factory for the acceptance of the elbow pipe?
Factory Acceptance
Customers may book a visit to the Plumberstar factory for on-site acceptance. We will arrange a dedicated staff member to assist throughout the process. During the visit, customers can verify the customized parameters, including angle, size, and wall thickness, check the surface finish, and confirm compatibility with the valve. Matching valve samples will be provided for on-site assembly testing. After all checks are completed and approved, the customer will sign the acceptance confirmation form.
Plumberstar Factory profile
7. Can you provide a “package customization scheme” for elbows？
Plumberstar offers integrated and customized solutions to help customers reduce communication and management costs.
First, the customer provides a list of valves to be matched, including the model, quantity, and installation position. Based on this information, we categorize the valves by “valve model + application scenario” and prepare a comprehensive list of elbow customizations, clearly defining the specifications, materials, and quantities for each elbow.
Next, we unify the adaptation standards for all customized elbows. Key parameters, such as flange bolt hole spacing and sealing surface type, are kept fully consistent with the corresponding valves. This avoids compatibility problems between customized products from different batches.
Finally, we provide a customized solution summary table. This table clearly shows:
The matching relationship between each elbow and its valve
The production lead time
Cost breakdown information
This makes it easier for customers to manage project budgets, schedules, and installation planning.
8. Can third-party inspections be arranged for the elbow pipe?
Plumberstar fully supports cooperation with third-party testing institutions. We work smoothly with globally recognized testing bodies, like SGS, BV, and TÜV. We also partner with domestic third-party labs designated by customers. It all depends on your needs. Test items cover every core performance indicator of stainless steel elbows.
Pre-Testing Preparation
We take the initiative to sort out all relevant documents. This includes product batch information, raw material qualification certificates, and production process records. These are ready for third-party institutions to check. We also set aside test samples. Each sample gets a clear label. We store them separately as per testing requirements. This way, they won’t get mixed up with products waiting for delivery.
During-Testing Collaboration
We assign special staff to coordinate with third-party testers. They’re with the team during factory sampling and on-site testing. These staff help solve technical coordination issues throughout the process. This keeps testing running smoothly. It also prevents any delays to your order delivery schedule.
9. How does factory-direct sourcing improve margins for the elbow pipe?
Plumberstar is a source manufacturer. We work on a factory-direct supply model. No traders, no regional distributors — we eliminate all middlemen and connect products directly to buyers.
In a traditional supply chain, every middleman typically adds a 5%–15% margin. That significantly increases the final purchase price. But with our factory-direct supply, this extra markup is gone entirely. Buyers can get stainless steel elbows at real ex-factory prices. On average, this cuts procurement costs per set by about 10%–20%.
For large-volume orders, Plumberstar also has tiered pricing based on how much you buy. The more you order, the lower the unit price. This helps customers save even more on costs and boost their profit margins.
