SPIRAL SAW PIPE

Spiral Saw Pipe (also referred to as SSAW Steel Pipe) is intended for fluid transportation and pressure applications and is also acceptable for ordinary is steam, water, oil & gas pipeline. It is made by Spiral Submerged Arc Welding Process.

SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, SY/T5037-2000 standard. These pipes mainly used in petroleum and natural gas industry as well as piling pipe.

In addition, we can also produce ERW (electric resistance welding) and LSAW (Longitudinal Submerged Arc Welding) Steel pipe, you can take a look of them and then decide which type ie better for your construction project.

Package of Spiral Saw Pipe

Plastic plugs in both ends, Hexagonal bundles of max with several steel strips, Two tags on each bundle, Wrapped in waterproof paper and sackcloth. Or according to customers; requirements.

RAW MATERIALS

THICK STEEL PLATE

We use thick hot rolled steel sheet as raw material of SSAW / HSAW steel pipes.

WELDING PROCESS

Spiral Submerged Arc Welding

We use double-side spiral submerged arc welding technique.

CHAMFERING PROCESS

CHAMFERING

We have chamfering machine imported from Germany.

HYDRAULIC PRESSURE INSPECTION

PRESSURE INSPECTION

Before SSAW pipe completed, there must be an necessary test measures-Hydraulic pressure test to avoid Defective goods.
