Description

Khớp nối dùng để Kết nối nhanh đường ống thay thế cho các phương pháp Kết nối đường ống truyền thống như Mối hàn và Mặt bích

Ưu điểm:

– Thời gian kết nối cực nhanh

– Nhẹ hơn nhiều so với Mặt bích, giảm khối lượng tổng hệ thống

– Không gây phát sinh tia lửa trong quá trình thi công nối ống

The NORMACONNECT® pipe coupling is a reliable connection for thick- and thin-walled pipes which conforms to the latest Standard DIN 86128.

Feed and return lines for liquids, gas and solids (for mechanical engineering and construction, civil engineering, shipbuilding, pipe line construction, power stations, mining, filters, water technology, etc. ) are joined quickly, easily and safely usingNORMACONNECT® pipe couplings.

NORMACONNECT® pipe couplings are an economical alternative to conventional pipe joining techniques for both plastic and metal pipes. All plain-ended pipes can be joined easily by hand. The ready to fit coupling is pushed over the pipe ends and then aligned and rotated to any fitting position. Tightening the two bolts alternately with a torque wrench is all it takes to make a safe fitting.

  • Sealing reliability is also ensured under the condition of slight axial misalignment, angular deflection and even gaps between pipe ends of up to 35 mm.
  • Pressure surges, vibration and related noise are absorbed to a considerable extent.
  • Economy is guaranteed due to short assembly times without the necessity of prior pipe alignment or treatment of pipe ends; in addition, the pipe couplings are reusable.

1. Double-lip Sealing System

The patented double lip seal (Fig. A) of the NORMACONNECT® pipe connection offers double safety; it provides maximum tightness at both low and high operating pressures. When the bolts are tightened sealing lip 1 is pressed on sealing lip 2 in such a way that also at low system pressures (gas) at vacuum or at high loads acting on the joint an excellent sealing effect is achieved (Fig. B).
Due to the special design of the sealing lips the sealing effect is even stronger when the internal pressure rises. With the increasing system pressure (P) the sealing lips are pressed more firmly onto the pipe surface (Fig. C).

2. Standard Strip Insert

All NORMACONNECT® pipe couplings are factory equipped with the standard strip insert (2). The strip insert protects the sealing sleeve from increased mechanical and chemical loads. It also prevents the sealing sleeve from moisture expansion and allows larger gaps between the pipe ends to be connected.
Furthermore, it allows larger angular deflections and misalignment.With the strip insert the couplings can also be used for both vacuum and high pressure applications without any problems. The strip inserts are made from plastic material or stainless steel and should be chosen depending on the application and the pipe material.

3. Heavy-duty Lock Bars

For NORMACONNECT® pipe couplings we use lock bars (3) with a larger diameter. Thus the rigidity of the coupling is increased and the engagement of the threaded end of the locking bolts is considerably improved.

4. Anchoring Ring with conically stamped teeth

The anchoring ring (4) with conically stamped teeth indents into the pipe surface and provides safe and stong axial restraint. Owing to the special design the coupling is able to withstand even high vibration loads.

5. Protection Ring

The protection ring (cf. FLEX / FLEX E) protects the sealing sleeve from UV rays, fire, etc. and increases the flexural strength of the coupling.
