HanSun Engineering产销造船，海洋设备，核动力、火力、水力发电设备的核心部件接头和阀门.

HanSun集团成立于1974年，总部位于韩国釜山，于1995年6月16日正式在KOSDAQ上市（股票代码：0025550）。经过40多年的发展和壮大，HanSun集团已成为最大的线材产品制造商，2013年实现销售额3亿美元。目前，公司拥有四个生产基地和一个欧洲子公司，其中镀锌钢丝，主要生产钢丝绳，绞合镀锌钢丝，不锈钢丝，型钢，轨道，海底电缆等。

2012年，Hansun集团100％收购Saehan Entech Co.，Ltd。成立Hansun工程有限公司。生产S-LOK系列产品。S-Lok正在尽最大努力为客户提供更好的技术和服务。

S-LOK管接头专为许多要求苛刻的应用而设计，如化学，石油，发电，纸浆和造纸以及各种制造行业。它们在所有管道连接上提供高度可靠，防漏和无扭矩的密封。 S-LOK管接头通常用于需要高质量管接头的仪表，过程和控制系统。

S-LOK管配件简介

S-LOK管接头在非常严格的质量控制下制造，以确保最可靠的性能。 S-LOK管接头无需特殊工具组装。通过简单的插入和拧紧螺母，可以快速轻松地进行连接。

S-LOK管接头专门设计用于化学，石油，发电以及纸浆和造纸厂的仪器仪表，过程和控制系统以及设备。 S-LOK管接头还可用于需要非常高质量的管接头的其他领域的广泛应用。

S-LOK管配件的结构

S-LOK管接头由四个精密部件组成;主体，螺母，前套圈和后套圈。

通过将螺母拧到主体上，螺母紧贴主体的锥形区域，并且通过向内卷曲将其边缘紧紧地压靠在管上。后套圈也位于主体和螺母之间。当前套圈滚动时，后套圈卷起并咬入管中，导致管和接头的连接以及无泄漏效应。

双套圈设计通过轴向传递通过管道的组装运动实现防漏密封。这导致管组装时没有径向移动。因此，管子没有受力并且保持了机械完整性。这是对加工中公差控制的密切监控以及S-LOK管件的每个部件的表面光滑度和硬度的结果。通过这种模锻动作，S-LOK管接头与连接的管机械地集成在一起。

Hansun Group was founded in 1974, Headquartered in Busan, South Korea, Officially listed on KOSDAQ in June 16, 1995（Stock code ：0025550）. After more than 40 years of development and growth, Hansun Group has become the largest manufacturer of wire rod products in achieving sales of $300 million in 2013. At present, the company has four production bases and a European subsidiary, where the galvanized steel wire, steel wire rope, stranded galvanized steel wire, stainless steel wire, section steel, rail, submarine cable, etc. are mainly produced. 

In 2012，Hansun Group 100% owned acquisition of Saehan Entech Co., Ltd. to set up Hansun engineering Co.,Ltd. to produce S-LOK series products. Sany Trading Company is China General Distribution of S-LOK which located in Bucheon City, South Korea. S-Lok is making utmost efforts to supply better technology and service to customers..

S-LOK Tube Fittings have been designed specifically for the many demanding applications such as chemical, petroleum, power generating, pulp and paper, and various types of manufacturing industries. They provide a highly reliable, leak proof and torque free seal on all tubing connections. S-LOK Tube Fittings are commonly used on instrumentation, process and control systems where high quality tube fittings are required.

INTRODUCTION OF S-LOK TUBE FITTING

S-LOK tube fittings are manufactured under very strict quality control to assure maximum reliable performance. S-LOK tube fittings require no special tools assembly. Connections can be quickly and easily made by simple insertion and tightening the nuts.

S-LOK tube fitting has been specifically designed for use on instrumentation, process and control systems and equipment employed in chemical, petroleum, power generating and pulp and paper plants. S-LOK tube fittings could also be used in extensive applications of other fields where very high quality tube fittings are required.

CONSTRUCTION OF S-LOK TUBE FITTINGS

S-LOK tube fittings are composed of four precision parts; body,nut,front ferrule and back ferrule.

By screwing the nut onto the body, the nut is tightened against the tapered area of the body, and its edge is compressed tightly against the tube by curling inward. The back ferrule is also located between the body and nut. As the front ferrule rolls, the back ferrule rolls up and bites into the tube resulting in the connection oftube and the fitting as well as a non-leakage effect.

The twin ferrule design achieves the leak proof sealing by assembly motion being transmitted axially through the tubing. This results in no radial movement of the tubing upon assembly. Therefore, the tube is not stressed and the mechanical integrity is maintained. This is the result of close monitoring of tolerance control in machining, and surface smoothness and hardness of each and every part of S-LOK tube fittings. Through this swaging action, S-LOK tube fittings are mechanically integrated with the tube connected.
