GOST 8734-75 Seamless Cold Formed Steel Pipe Carbon Steel Seamless Pipe 0

GOST 8734-75 Seamless Cold Formed Steel Pipe Carbon Steel Seamless Pipe

Material

GOST 8734-75 seamless cold formed steel pipe is a carbon steel seamless tube produced by cold drawing or cold rolling to achieve tighter dimensional tolerance, smoother surface quality, and better consistency than conventional hot-finished tubing. It is widely used where buyers need reliable strength, clean internal and external surfaces, and stable OD/WT control for further machining, hydraulic use, and structural/mechanical assemblies. GOST 8734-75 defines the size range, while technical delivery requirements are typically applied together with GOST 8733-74.

Specifications

Standard: GOST 8734-75
Related technical requirements: GOST 8733-74
Product type: Seamless cold formed steel tube
Manufacturing process: Cold drawn / cold rolled seamless
Outside diameter range: 5-250 mm
Wall thickness range: 0.3-24 mm
Length:
- Random length: 1.5-11.5 m
- Fixed length: 4.5-9 m
- Multiple length: 1.5-9 m
Wall classification:
- Extra-thin wall
- Thin wall
- Thick wall
- Extra-thick wall
Common steel grades: 10, 20, 35, 45, St3sp, and other agreed grades depending on end use and supply condition.

Main Features

High dimensional precision from cold-forming
Smooth, clean surface suitable for machining and coating
Seamless structure for dependable pressure integrity
Uniform wall thickness and improved concentricity
Good machinability across common carbon steel grades
Wide grade selection for strength, formability, and weldability balance
Suitable for hydraulic, mechanical, automotive, and general engineering service.

Our Advantages

Buyers worry about dimensional tolerance and fit-up consistency.
We supply cold formed seamless tubes specifically for applications where OD/WT consistency matters. Compared with hot-finished tube, cold drawn tubing offers tighter dimensional accuracy, better wall uniformity, and smoother surfaces, which helps reduce secondary machining and assembly deviation.
Buyers worry about surface quality for hydraulic and precision parts.
GOST 8734-75 products are widely selected for hydraulic systems, mechanical structures, and precision-use components because cold forming provides a cleaner surface and improved finish. This is especially useful for cylinders, sleeves, bushings, and machined assemblies where surface defects increase rework risk.
Buyers worry about standard compliance and material traceability.
We organize production around the GOST route clearly: GOST 8734-75 for dimensions and assortment, GOST 8733-74 for technical requirements, and the corresponding grade standards such as GOST 1050 or GOST 380 for chemistry and mechanical properties. This makes procurement documentation, inspection records, and material substitution much easier for international projects.
