Haihao Group Supplies Seamless 15X5M/P5 Pipe Fittings to Latvia

Haihao Group has completed a shipment of 15X5M/P5 seamless pipe fittings for a customer in Latvia. The order includes 90° long-radius elbows, concentric reducers, equal tees, and reducing tees manufactured to the specified GOST standards. The fittings are supplied as seamless products, with welded alternatives specifically excluded from the order requirements.

The combination of 15X5M/P5 material, seamless construction, and GOST dimensional requirements makes this order suitable for pipeline systems where material consistency and controlled fabrication are important.

15X5M/P5 Seamless Fittings for the Latvian Order

The supplied fittings cover several common pipeline configurations. The 90° elbows are specified as 3D long-radius elbows with a radius of 1.5DN, while the reducers and tees are produced according to their respective GOST standards.

For this project, 15X5M/P5 seamless fittings were specified without welded construction. This requirement was applied to the elbows, reducers, and tees in accordance with the customer’s purchase specifications.

Material Requirements for 15X5M/P5

The supplied material is 15X5M, corresponding to the P5 material designation used for the order. The customer’s specified chemical composition requirements include:

• Carbon (C): ≤ 0.15%
• Silicon (Si): ≤ 0.50%
• Manganese (Mn): ≤ 0.50%
• Chromium (Cr): 4.5–6.0%
• Nickel (Ni): ≤ 0.60%
• Molybdenum (Mo): 0.45–0.60%
• Phosphorus (P): ≤ 0.03%
• Sulfur (S): ≤ 0.025%

These limits were part of the technical requirements for the 15X5M/P5 seamless fittings supplied for the Latvian project. Maintaining the specified alloy composition is important when fittings are purchased for systems requiring controlled material properties.

GOST Standards and Dimensional Control

Different fitting types in the order are covered by different GOST standards.

The elbows are manufactured according to GOST 17375-2001, with the supplied products specified as 90° long-radius, 3D fittings. The 159.0 × 6.0 mm elbow has a radius of 225 mm, while the 219.0 × 8.0 mm elbow has a radius of 300 mm.

The concentric reducer follows GOST 17378-2001, with a size transition from 426.0 × 12.0 mm to 325.0 × 10.0 mm and a specified length of 220 mm.

The tees are manufactured according to GOST 17376-2001. Both equal and reducing configurations are included, covering sizes from 108 mm branch dimensions up to 325 mm main dimensions.

For projects requiring 15X5M/P5 seamless fittings, matching the fitting geometry with the applicable GOST standard is just as important as selecting the correct material grade.

Haihao Group’s Manufacturing and Inspection Approach

For an international order involving 15X5M/P5 seamless fittings, Haihao Group focuses on the requirements specified in the purchase documentation rather than treating the fittings as standard off-the-shelf items.

The production and inspection process covers key points such as:

• Material grade and chemical composition requirements
• Seamless construction
• GOST dimensional requirements
• Elbow radius and fitting geometry
• Reducer dimensions and length
• Tee branch and run dimensions
• Surface condition and final dimensional inspection
• Identification and documentation before shipment

The fittings are supplied for a Latvian customer with the technical information clearly defined by product type, size, material, and applicable GOST standard.

Why Choose Haihao Group for GOST Pipe Fittings?

Haihao Group supplies industrial 15X5M/P5 seamless fittings and other carbon steel, alloy steel, stainless steel, and special-material pipe fittings for international pipeline projects.

For customers purchasing fittings under GOST or other international standards, the practical requirements often extend beyond simply specifying a nominal size. Material grade, seamless construction, dimensional details, manufacturing standard, and inspection requirements all need to match the project documentation.

Haihao Group can support customers with customized fitting specifications, including elbows, tees, reducers, and other pipeline components. Send us your size, material, applicable standard, quantity, and technical requirements to request a quotation.
