Certification
All materials are strictly inspected at every stage of the production process from procurement to product shipment. Visually inspect them for compliance with ASTM, ASME, MSS, DIN, EN and JIS codes and standards. Support officially certified inspection agencies to witness product material reporting, dimensional and quality compliance. Factory inspections are also supported.
Product Description
The roundness of the reducer should not be greater than 1% of the outer diameter of the corresponding end, and the allowable deviation is ±3mm. The material of the reducer complies with SY/T5037, GB/T9711, GB/T8163, American standard ASTM A106/A53 GRB, API 5L, APT5CT, ASTM A105, ASTM A234, ASTM A106, DIN German standards and customer requirements.
Reducer (big and small head) is a pipe fitting used at the pipe diameter reduction point. The commonly used forming processes are reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing. For certain specifications of reducers, stamping can also be used.
a. Diameter reduction/diameter expansion forming
The reduction forming process of the reducer is to place a tube blank with the same diameter as the large end of the reducer into the forming mold, and by pressing the tube blank along the axial direction, the metal moves along the mold cavity and shrinks to form. According to the size of the reducer, it is divided into one-time press forming or multiple press forming.
Diameter expansion forming is to use a tube blank that is smaller than the diameter of the large end of the reducer, and use an inner punch to expand the diameter along the inner diameter of the tube blank. The diameter expansion process mainly solves the problem that the reducer with a larger diameter cannot be easily formed by diameter reduction. Sometimes, the diameter expansion and diameter reduction methods are combined according to the material and product forming needs.
During the deformation and pressing process of diameter reduction or expansion, cold pressing or hot pressing is determined according to different materials and diameter reduction conditions. Under normal circumstances, cold pressing should be used as much as possible, but hot pressing should be used when multiple diameter changes cause severe work hardening, when the wall thickness is too thick, or when alloy steel materials are used.
b. Stamping forming
In addition to using steel pipes as raw materials to produce reducers, some specifications of reducers can also be produced using steel plates using the stamping forming process. The shape of the punch used for drawing is designed with reference to the inner surface dimensions of the reducer, and the punch is used to punch and stretch the blanked steel plate into shape.
Classification
1. Divide by material:
Carbon Steel: ASTM/ASME A234 WPB, WPC
Alloy: ASTM/ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP911, 15Mo3 15CrMoV, 35CrMoV
Stainless steel: ASTM/ASME A403 WP 304-304L-304H-304LN-304N
ASTM/ASME A403 WP 316-316L-316H-316LN-316N-316Ti
ASTM/ASME A403 WP 321-321H ASTM/ASME A403 WP 347-347H
Low temperature steel: ASTM/ASME A402 WPL3-WPL 6
High Performance Steel: ASTM/ASME A860 WPHY 42-46-52-60-65-70
Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon phosphate, PVC, PPR, RFPP (reinforced polypropylene), etc.
2. According to the production method, it can be divided into pushing, pressing, forging, casting, etc.
3. According to manufacturing standards, it can be divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
4. According to its radius of curvature: it can be divided into long radius elbow and short radius elbow. A long-radius elbow means that its radius of curvature is equal to 1.5 times the outer diameter of the pipe, that is, R=1.5D; a short-radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R=1.0D. (D is the diameter of the elbow, R is the radius of curvature). 5. If divided by pressure level: there are about seventeen types, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; the most commonly used ones are STD and XS.
