District Heating Industry Expansion Joints
Introduction:
This is widely used and most economical type expansion joints. Since 1993 years, thousands pieces of expansion joints were widely and huge quantity used in district heating industry. And we had designed and manufactured burying expansion joints, external expansion joints and slide expansion joints applied in district heating industry. And the expansion joints we designed and produced with big movement (200mm axial), lower pressure thrust, corrosion resistance and high cycle life. And we had gained customers' agreed trust and good reputations.
Specification:
| Burying bellows expansion joints |
| Diameter:DN15mm-DN1200mm |
| Pressure rate:0.6Mpa,1.0Mpa,1.6Mpa,2.5Mpa |
| Material:Bellows and Inner sleeve adopt SS304,SS321,SS316L.Outer cover, weld ends (flanges) and tie rods adopt carbon steel. |
| Connection Type:Flanges or weld ends |
| Mainly used for absorbing in-line direction axial movements caused by heat expansion and contract. It has the ability of soil pressure resistance, self-direction. And this product have the limited devices while 100% pushed and pulled. And we can also do the corrosion treatment if customer requested. |
| Filler slide expansion joints |
| Diameter:DN80mm-DN1200mm |
| Pressure rate:0.6Mpa,1.0Mpa,1.6Mpa,2.5Mpa |
| Material:Carbon steel, Flexible graphite packing, PTFE packing, Flexible graphite, antioxidant, sealing oil etc. |
| Connection Type:Flanges or weld ends |
| It is contact-type sealing. Fill elastic seal material between outer tube and inner tube. The filled seal material will be compressed onto the surface of the inner tube when there is any axial force effected. It can avoid the leakage of the medium by the transform of the seal material, and until now the filler had developed from single type to be combination type. |
| Machinery sealed slide expansion joints |
| Diameter:DN80mm-DN1200mm |
| Pressure rate:0.6Mpa,1.0Mpa,1.6Mpa,2.5Mpa |
| Material:Carbon steel, FKM O ring, FKM Y ring |
| Connection Type:Flanges or weld ends |
| Three high precise sealing, no leakage, avoid frequent repair of common type slide expansion joints. |
