Haihao Group Ships 08X18N10T Seamless 90° Elbows to Latvia
Haihao Group has completed a shipment of 08X18N10T seamless 90° long-radius elbows for a customer in Latvia. The order covers five sizes, from 32.0 × 4.0 mm to 325.0 × 12.0 mm, manufactured according to TU U 24.2-13419172-005-2014.
The order is notable for its combination of 08X18N10T stainless steel, seamless construction, specified bending radii, and intergranular corrosion testing requirements. Mechanical testing, hydrostatic testing, and 100% ultrasonic testing were also specified for the supplied fittings.
08X18N10T Stainless Steel Elbow Order for Latvia
The Latvian customer required 90° long-radius seamless elbows in five different dimensions. Each item uses 08X18N10T material and follows the same technical specification.
| Product | Type | Size | Wall Thickness | Material | Standard |
| 90° Long Radius Elbow | Seamless | 76.0 mm | 5.0 mm | 08Х18Н10Т | ТУ У 24.2-13419172-005-2014 |
| 90° Long Radius Elbow | Seamless | 32.0 mm | 4.0 mm | 08Х18Н10Т | ТУ У 24.2-13419172-005-2014 |
| 90° Long Radius Elbow | Seamless | 273.0 mm | 6.0 mm | 08Х18Н10Т | ТУ У 24.2-13419172-005-2014 |
| 90° Long Radius Elbow | Seamless | 133.0 mm | 5.0 mm | 08Х18Н10Т | ТУ У 24.2-13419172-005-2014 |
| 90° Long Radius Elbow | Seamless | 325.0 mm | 12.0 mm | 08Х18Н10Т | ТУ У 24.2-13419172-005-2014 |
The five 08X18N10T stainless steel elbows cover different pipe diameters while maintaining the same material and manufacturing specification. The specified bend radii are also recorded in the order, allowing dimensional inspection to be carried out against the customer’s requirements.
08X18N10T Material and Chemical Composition
08X18N10T is the material grade specified for this shipment. The customer’s chemical composition requirements include controlled levels of carbon, silicon, manganese, nickel, sulfur, phosphorus, chromium, and copper.
| Element | Requirement |
| C | ≤ 0.08% |
| Si | ≤ 0.80% |
| Mn | ≤ 2.00% |
| Ni | 9–11% |
| S | ≤ 0.02% |
| P | ≤ 0.035% |
| Cr | 17–19% |
| Cu | ≤ 0.30% |
The material requirements are particularly important for this order because the fittings were specified with an intergranular corrosion resistance requirement. The purchase information states that the products must pass the A262 E method for intergranular corrosion testing.
For customers sourcing 08X18N10T stainless steel elbows, controlling the actual material chemistry is therefore an important part of quality verification rather than simply identifying the grade on the product label.
Intergranular Corrosion Testing
The order specifies protection against intergranular corrosion and requires compliance with ASTM A262 Practice E testing.
This requirement was applied to all five sizes in the shipment. ASTM A262 practices are used to evaluate susceptibility to intergranular attack in austenitic stainless steels. For this project, the customer’s specified testing requirement was incorporated into the inspection process.
This is especially relevant when stainless steel fittings are intended for service where material condition and corrosion resistance need to be demonstrated through testing rather than assumed from the nominal grade alone.
Seamless 90° Long-Radius Construction
All products in this shipment are seamless 90° long-radius elbows. The order provides specific radius values for four of the five sizes:
32.0 × 4.0 mm — R=38 mm
76.0 × 5.0 mm — R=100 mm
133.0 × 5.0 mm — R=190 mm
273.0 × 6.0 mm — R=375 mm
325.0 × 12.0 mm — radius not separately stated in the supplied order information
The dimensional information helps ensure that the elbows can be checked not only for outside diameter and wall thickness but also for their bending geometry.
For a 08X18N10T seamless elbow, radius control is important because the fitting geometry directly affects its installation dimensions within the pipeline.
Inspection Requirements for the Shipment
In addition to material and dimensional requirements, the order specifies several inspection items:
- Mechanical property testing
- Hydrostatic testing
- 100% ultrasonic testing
- Intergranular corrosion testing according to ASTM A262 Practice E
- Verification of the specified chemical composition
The requirement for 100% ultrasonic testing provides an additional non-destructive examination step for the seamless fittings. Rather than relying only on visual and dimensional inspection, the customer’s specification requires ultrasonic examination across the supplied products.
The combination of material verification, mechanical testing, hydrostatic testing, corrosion testing, and ultrasonic examination provides a more complete quality-control approach for this Latvia shipment.
Manufacturing to the Customer’s Specification
The fittings are manufactured according to TU U 24.2-13419172-005-2014, with the product descriptions identifying the elbows as stainless steel 90° fittings made from 08X18N10T.
For international orders, Haihao Group pays close attention to the details that can affect final acceptance: material chemistry, dimensions, radius, testing requirements, and applicable technical documents.
This order is a good example of a project where the requirement is not simply “stainless steel elbows.” The customer specified a particular material grade, five individual sizes, seamless construction, bending radii, corrosion testing, and non-destructive examination.
