A pipe bend looks like a elbow of different bending radius.The most regular pipe bends are 30 degree, 45 degree, 90 degree, the popular bending radius are 3D, 5D, 7D, 10D,here the “D” means the nominal diameter of this bend.90° pipe bend 3D is the most commonly used.
We regularly supply to one of our Europe customers. Their requirements are very strict. Commonly the thickness is guaranteed for both ends. But customer request the thickness for all the part including extrados should be guaranteed. It will cost much in this case because we need prepare much thicker material to reach their thickness requirement.
They also request pickling for the material. This is also very difficult because the volume of bend is large, and few pickling bath can accommodate it. But we overcome the difficulty and make it.
Both ends of the bends are beveled, they want the ends can be well protected, so they ask us to protect with plastic caps. And we sheath plastic film for each bend.
These pipe bend 3D are used in Oil & Gas projects.Our pipe bends help them perfectly finished the projects.
Haihao Group supply pipe bend 3D with high quality and competitive price,of course,also good service.If you have any inquiry of ASME B16.9 or other standard D, please do not hesitate to contact us.
