BPE Pipe Fittings Series
Hope BPE pipe fittings using online solution technology, stainless steel surface bright, strong toughness, no intergranular corrosion phenomenon, smooth weld, not easy to crack, good corrosion resistance.
Hope produce ASME-BPE and ASTM A270 S2 specifications tubes,We only use Outokumpu Material for ASME BPE products.
All of these tubes are polihsed both in ID AND OD.
It is possible to control the sulfur content in the steel pipe to 0.005-0.007, which is more conducive to orbital welding.
Hope can provide 1/2 inch to 8 inch ASME BPE tubes in 6 meter or 6.1 meter.

Additional Information
Our advanced clean pipeline adopts the international leading hydraulic test system
Mechanical performance test system
Crystal phase analysis system
Strict control of pipeline size
Strict control of tolerance size
SPECIFICATIONS
Hope uses Outokumpu material to ensure the mechanical properties of the material, tensile strength, corrosion resistance, at the same time, Hope do the polishing of the steel pipe will exceed the BPE standards, the polishing requirements of our SF1 will generally reach about 0.4um, the appearance will be less than 0.6ra. Roughness are measured per ASME/ANSI B46.1, And we only use mitutoyo to measure the roughness.
ANNEALING
Tubing is hydrogen bright annealed in line to 1900°F (1040°C) minimum and rapidly quenched.
CLEANING
A270-BPE high purity tubing ID and OD will be cleand in the factory
PACKAGING
To ensure the cleanliness of the tubes, we use plastic bags and caps to prevent subsequent dust ingress.SURFACE FINISH
